and tweaked the model until I thought it sounded like one. Hopefully that was a series of flukes though that the guy I'm talking about had. Within that article he mentions Ty Tabor being a favorite player of his. Made from Baltic Birch, and handcrafted with pride in the USA this is a sturdy build that can be relied upon on stage or the road. Too much causes excessive even-order harmonics which makes things fuzzy and indistinct. The model defaults the Depth to match this. If you want "active" EQ you need to set the type to Active. This occurs because the Legacy has so much negative feedback (12 dB, which is the highest of any amp I've ever modeled). You are using an out of date browser. ", "A 5150 uses a fixed bias with no adjustment. The Gear Page is the leading online community and marketplace for guitars, amps, pedals, effects and associated gear. You then have the separate graphic EQ to further tailor the sound. ", "Based on a Fender AA964 Princeton. This can lead to further damages to the innards and potentially even be a dangerous thing to do. Or you can lower the Harmonics value which reduces the asymmetric distortion. The seperate eq and the tube driven effects loop were added for that situation. Unfortunately the bias points aren't exposed to the user. ", "The bright cap on the X99 Clean is not across the Drive pot. ", "The reason they clean up when you back off the volume is because the OT is so overmatched. If anything it should be linear. ", "If it isn't Mid Gain then it's Harmonics. After three decades as an amplifier guru to the stars, Dave Friedman knows a thing or two about classic British rock tone and claims there's plenty of life left in the 100-watt amplifier head. With everything at noon the tone stack looks like a highshelf with a good amount of high frequency cut. Over the decades, the company faded in obscurity, but some veteran rockers, such as Neil Young, still retained Magnatones in their backline. ", "The amp has no hi-cut circuit therefore the control won't do anything. ", "All these amps have the same basic circuit with minor differences. No it isn't. ", "Treble Shift on the Tone page of USA IIC+ models is an alias of the Fat control found on the Preamp page and performs the same function." The capacitor on the cathodes charges up and shifts the bias point. For a better experience, please enable JavaScript in your browser before proceeding. For now note that V1/V2 refer to the newer amp and represent the position of the Voicing switch. It's the IIC+ model with different tapers. Of course the power amp adds to the harmonic content, but it adds very little overdrive. "The previous model wasn't based on any real amp. Turn down the Preamp Bias Excursion to reduce it. ", "Yeah, it's a cool little amp. ", "I can nail the sound of my Triaxis now by setting it (Bright) around 9:00 - 10:00. ", "Combines the best features of the British (Marshall) and USA (Mesa) crunch models. Friedman Amps. ", Lead mode, Preamp Bypass ON (tone controls bypassed), "It's very smooth but there's this unique chirp or something that I've never heard in an amp before. He checked and, sure enough, 12AX7A in V1. ", "The CA3+SE model is basically an OD100. ", "The Badger doesn't have a Bright switch. He found himself working at Andy Breuer Studio Rentals, one of the biggest gear resources for studio musicians on the scene, where he quickly developed a reputation as a tech. Copyright 2022 Friedman Amplification. At the time I paid $50K for both. Sort of a Fender-meets-Vox thing. ", Rhythm channel with Crunch switch engaged, "I have a "holy grail" Block Letter 5150 (supposedly). It's basically a brief explosion of noise. Bear in mind that its function and tone that the average player is looking for, not a particular design architecture. Why they chose a log taper in the 5150 is a mystery. Small grid stoppers or bypass caps on the grid stoppers, no plate caps, etc. This means the amps are biased somewhat cold to begin with and shift to very cold as soon as overdriven. Totally different model. The new BE-100 Deluxe, like its little brother the BE-50 Deluxe, takes this BE circuit to a whole new level, This new BE-OD Deluxe pedal employs the exact same circuit but adds another channel and dual midrange controls. I don't like it in the middle. Therefore, the Bass/Mid/Treble controls when using Authentic Tone Controls are mapped to the Graphic EQ. Probably because it's so nasty with it in. ", (Def Leppard) "The amp model you are looking for is "JMPre-1 OD1". He also said that this "other" company made other company's amps as well. Nasty, spitty, Neil Young-esque blocking distortion and all. The foot controller and bias monitor are two of the wonderful features of the actual amp, but are both moot in the modelunless Cliff wants to model the effects of real world mains power fluctuations from place to place, but the 'green zone' of the bias monitor is 62-65% plate idle dissipation power and it measures and compensates for plate voltage and screen power , which means the real amp runs best at a slightly cooler bias. With PAB active this lowers the lowcut frequency. IOW all over the map. Looks like it was that way from the factory. For me I would rather focus on that tone in a Plexi Marshall, but who knows what the original guy he modified this for wanted. ", "The Buttery model was REPLACED by a Budda Twinmaster model. The amp model, regardless of how accurate it is (and it's probably grossly inaccurate as I never compared it to any actual amp) is very popular and that's why it was never matched to any real amp. The model matches that particular amp very well. You can find out more about him here. Our model is based on the Canadian one. ", (differences between Peavey 5150 and 6505) "There are differences. If you do this on a Bogner it's like turning the treble way down on a Marshall. Don't mess with extended parameters, basically don't try and redesign it. Some distortion pedals also do this. (firmware 22), (from Metallica engineers) "This model is part of our live sound. Los Angeles, California friedmanamplification.com Joined September 2014. This is not exposed to the user though (there's a hidden shared/split switch). Handmade in the USA its a premium amp with an incredible broadcasting volume that can come as a surprise. For all the hoopla surrounding Trainwrecks they're actually pretty bad designs. ", (fuzzy lows) "That's what those amps do. ", "Maybe the best clean model IMO. If you turn it up too high it will flub out really quick. It is similar to the previous versions but voiced a bit different. A friend told me that there was a video somewhere of Mr. Friedman saying that he didn't want (to pay) employees so there's another company that makes the majority of their amps, with exception to a few that are still handwired in the USA. It has a boatload of gain and sounds more like a Plexi than a Fender. ", "The "Treble" knob on the Chietain model is actually Preamp Presence. The model is based on using the matching cab. ", "The real amp has Overdrive Volume (sometimes labeled Ratio) and a Master Volume. When you hit the note there's this blast of high end that rapidly decays so it has an almost vocal quality. ", "If you want more clarity in the low mids from the BE/HBE reduce Negative Feedback. Whether you require it for your profession, passion, or hobby, youve purchased it to enjoy and so protecting it from the point of purchase can be invaluable. ", "Rips my head off here. For a better experience, please enable JavaScript in your browser before proceeding. ", "The Master Volume in a Blues Jr. is linear taper. Takes the guesswork out. There's a single fixed tube screamer circuit at the input of the amp. ", "People think Bogners are dark but they really aren't. I've reduced the default for Quantum 2.03. Negative feedback linearizes the amp and reduces the crossover distortion (at the expense of gain). ", "That's based on my favorite Plexi. "I begrudgingly dragged the amp out of storage today (as it weighs a metric ton) and repeated the measurements and did some A/B tests. To simulate the lower gain input simply set Input Trim to 0.5. Sound great though. Furthermore, Friedman personally inspects, plays, and even signs every single amplifier before shipping! ", "Our reference amp is a head with matching 1x12 cab. Check Price It has cathode bypass caps giving it more gain. EVH ostensibly liked his amps biased cold to get some crossover distortion. AB. ", (Gain) "It's a ganged pot so it behaves strangely. This causes a lot of distortion and also a lot of bias excursion before the drive control with no way to control it. Whether or not the model matches any particular Dumble is unknown as we have not been able to procure a non-HRM Dumble yet. For instance, Splawns are all built in house by 3 guys and are half the price on most models, but they are not sold in Guitar Center's throughout the country. This is a topic that comes up frequently on this board with lots of strong opinions in tow. ", "The BE has very light power supply filtering like old Plexis. Here are some thoughts from Dave on his Tone Talk podcast. That's why the buzzing went away when you increased negative feedback. ", "It has a master volume. ", "A typical Recto cabinet has a resonant frequency a little over 100 Hz. If you don't push the power amp all you are hearing is the preamp which is voiced to be trebly. S-taper will give you approximately linear-in-dB. Friedmans amps guts I've seen are nicely made, but nothing to write home about. Simple circuits with minimal frequency shaping. As such there's a lot of bass going into the power amp. Great amp and punches well above its (used) price point. This bypasses the EQ for more gain. Famed for his exacting and innovative amp building, modding, and repairing, Friedman finally branched out and developed his own line of amplifiers. We earn a commission if you make a purchase, at no additional cost to you. ", (negative feedback) "I've seen JTM45s with 27K off the 16-ohm tap. ", "I have a 1974 Hiwatt DR-103. ", "I always used the Fat switch with the real amp." If you turned the treble up to 8 or 9 it would sound a lot like a Plexi but humans are reticent to turn the knobs to extremes. It's got six (!!!) Friedman Amps In the world of vacuum tubes, pentodes, and transformers, Dave Friedman is a legend among legends. ", "The actual amp has no tone stack and a single tone control. Jodie fell in love with the guitar at a young age, but has hit a lot of bumps in the road with her journey. That's one of the "mods". Then there's shared vs. split cathode. Consider a pro cover insurance plan at the point of sale this will often include replacement amps, or unlimited repairs, for up to 5 years. ", "The unique thing about a Dual Recto tone stack is that the Presence control is part of the tone stack. Tons of blocking distortion in the PI. ", "All the Fender models except the 59 Bassman and 5F8 Tweed don't have cathode followers. Trainwrecks have plate suppressor diodes for just this reason. Now, if you like, put a Zen drive in front on the BludoClean amp.or a boostand listen to how that clean channel wakes up fast for grittier leads and touch-responsiveness. ", "The reference amp used for our model is a Canadian Export version (with the "bat handle" power switches). I really liked the idea of driving the tonestack from a common cathode stage as opposed to a cathode follower like a Marshall because it got rid of some of the artifacts I don't like with say a JCM-800. The Vibrato Lux model is based on the same model and year amp used on the eponymous album. ", "Just finished matching this modded 65 Bassman that Dweezil sent me. This type replicates the active EQ used in the JMP-1 preamp. They exist solely in the virtual world. Personally I hate the 39K resistor. ", "The amp has a Hi Cut but it's labeled Brilliance. big caps filtering the B+. Firmware 19.02 and later for the Axe-Fx III: Added JMPRE-1 Output EQ type to Amp block. ", "The model is extremely accurate and is based on a 1966 Blackface Twin Reverb. Neither will the Depth. For anyone that has played a number of real Dumbles, there is a certain thing (I hear it more in the clean channel) that is uniquely his signature. Negative feedback linearizes the amp and reduces the crossover distortion (at the expense of gain). As was indicated in the release notes you can dial out this behavior by decreasing the PI Bias Shift. But even with the snubber cap corrected it's still very dark and boomy which made me question as to whether there are other components that are incorrect. So the output impedance is lower. The real amp does the same thing but you wouldn't normally use a subwoofer with one. Our world famous amplifiers. ", "The Pull Bright on the Volume knob is the classic "Bright Cap" which engages a capacitor across the potentiometer. With the Presence Shift on the JP IIC+ will be very similar to the Mark IV with its Presence Shift on. Clean channels only: the passive tone stack itself, however, is adjustable. ", "The Depth knob is inactive on that amp model. The model's Presence knob is therefore the Power Amp Presence. The 2:90 power amp is basically the same as a MarkIV and does have a presence shift but it's accessed through a jack on the back (Voicing). AC-30's are very sensitive to the tube type and part tolerances. The preamp has about +/- 8 dB for each tone control while the model has the standard +/- 12 dB. The Tucana falls in to this category. As you keep raising the MV the source resistance then starts to decrease as you get above 50% of the pot value. Often called the best amplifiers in the online guitar world, Friedman amps have an excellent build quality, high and low inputs, awesome loop and master, and are fun to play, requiring minimal tweaking. If it is too bright, you can adjust the various tone controls and parameters to reduce the brightness to your tastes. J. The way I see it, if you have something like a simple 1-2 channel amp then yeah, maybe handwired is fine. ", "What you are hearing is output transformer high frequency resonance. ", "I intentionally limited the midrange notch since, IMO, it's a design flaw in that tone stack. Both with the Lead 1 Red board. ", "IMO the designs are poor because wait for it they exhibit a papery buzz. The Axe-Fx III is precisely linear-in-dB. I found the 12L emulation did a pretty good job. I just tuned it by ear. ", "The model was matched to Dweezil's amp. ", (firmware Ares 14.00) "The Tube Pre model has been changed so that the power amp is off by default. ", "I did the Buttery model by ear. ", "SV's personal settings are: Drive: 7.5, Bass: 6, Mid: 4, Treble: 8, Presence: 8. Main reason I can't get along with them. ", "The JVM has a huge plate resistor on the cathode follower, the JS does not. It biases the stage much too cold for my tastes. The worst amp in this regard is the Badger 18. You can also try reducing the Master Bias Excursion but that won't get rid of the pre-drive control distortion. Totally different preamps and, therefore, different sound. Once the power amp starts clipping the tone will change. ", "You have to be very careful with the Master Volume. The reason they seem that way is the pot tapers. Fryette Power Station would be nice but I'm not wanting to drop that much. Always been that way. I always use the Presence Shift. This reduces the signal level substantially and lessens the amount of blocking distortion.". After a rigorous burn in process, Dave inspects, tubes, plays and signs the chassis of every amplifier before shipping. ", ("Cygnus" amp modeling) "The 5E3 model is now "jumped" so it has both Normal and Bright drives. ", "The Mid switch, sometimes labeled "Deep", shorts out the 390 pF cap in the tone stack (which is in series with a 2 nF cap). No other amp has anywhere near the amount of treble boost. It's a unique compression and the amp "opens up" at the same time and crossover distortion increases. To simulate this lower the negative feedback by 1/sqrt(2). This causes lots of crossover distortion (papery buzz). Not sure about an effects loop. The loop send is taken right off the MV which means the output impedance is very high. On a Mark V the tapers are different so you get more midrange and treble for the same settings. The model defaults to the bright cap in the circuit. Friedmans innovative designs and meticulous construction have made him legendary in the world of professional touring musicians while earning him a loyal clientele from all over the world. Our model is based on a 1981 2204 Master Volume JMP. Just listen to Pete Thorn's demo of the Pink Taco 20-watt head - "no pedal required" indeed! The Preamp Tube Type parameter only affects the tubes after the input buffer. For a better experience, please enable JavaScript in your browser before proceeding. This is ridiculous as it makes it very difficult to find the sweet spot. ", "Reference amp is a Slash AFD100 Signature Special Collector's Edition #76. Negative feedback linearizes the amp and reduces the crossover distortion (at the expense of gain). Thats common knowledge, I've talked about it in depth many times. Regularly give the amp a wipe over, with a damp soapy cloth, to prevent a build-up of mold or mildew. The Runt-50 combo houses the responsive and articulate G12M 65 Creambackspeaker, which delivers classic British tone with a warm body and distinctive growl. That's low but it does affect subharmonics due to intermodulation. Classic American Clean sound To a classic British crunch. The preamp is virtually identical to a Twin Reverb but 6V6s break up earlier than 6L6s. I.e. Otherwise it's too flubby. Crude. It has the feedback of the 4-ohm tap whereas I've heard later versions have the feedback off the 8-ohm tap. . The causes the power tubes to clip much sooner. It recaptured the legendary sound of Celestions 1970s, due to its Celestion Greenback 10 inch speaker, yet with a deep tone that can come as a surprise. Otherwise you would just engage the Bright switch under the Treble knob. al. Too high and will get muddy. Otherwise things are pretty similar. This particular amp is an early CBS Silverface but still using pre-CBS design and components. dave coleman author meet the writer amp discover his work "Resea del editor cryptozoology (n.) . Despite it's name, DV is just an EQ. If you like the SLO-100 model you might want to try the Recto models too. Lower values are looser. The Atomica is essentially a slightly modified JCM800 with a Jose-style zener clipper. ", "The feedback circuit is responsible for the behavior of the Presence and Depth controls. Not sure why. ", "I used the power amp models from the XTC. This results in a negative feedback value of 3. Many JTM45s did not but I think they sound better with one. When you do this the low notes get very muddy. ", "A signal divider, which is more correctly called a voltage divider, is calculated by taking the resistance to ground divided by the sum of the resistances. Always consult the official Owners Manuals first! ", "As with the real amp I dial in quite a bit of Hi-Cut. It's supposed to be a 12AY7 but many clones have a 12AX7A in V1." 7.02 is faithful to the actual amps whereas previous firmwares were more idealized. There are even some amps that have circuits to intentionally generate crossover distortion. All of the saturated, complex harmonic overtones are still lurking inside, as well as the AC30-like cleans. We are a community of guitar players, and enthusiasts and we want to spread the love for music to anyone with the heart to play. Over the past 25 years, Dave Friedman has built, tweaked and modded guitar amps for some of the world's most renowned players. ", "It's unique character comes from the PI. ", "I bought a Budda Twinmaster, pulled it apart and traced the circuit since I couldn't find a schematic for it anywhere. ", "The input to the second 12AX7 is a summing node. With varying prices and different functions, there can be significant differences between Friedman amps. This was a happy accident when originally modeling the Carr Rambler in the beta version of this release. The information also partly applies to the previous generation of modelers (Axe-Fx II series and AX8). They sound different.

I think it was probably a mistake but then they said "Hmmm, but it sounds good so don't fix it". Most Friedman amps are hard-wired, which, in short, means they take longer to create and are done so by hand offering more longevity, reliability, and durability over mass-produced, machine-made amps. As soon as I changed the model to split cathode it was spot on. My Runt 50 is far and above the best sounding amp I've ever owned. You can learn more About Us here. When you run a pentode (or beam tetrode) in triode mode you connect the screen to the anode which effectively defeats the screen. ", (about moving Master volume to the post phase inverter) "It's called PPI MV or the "Lar-Mar Mod". ", (firmware Quantum 7) "The USA Pre models now all use a MarkIV power amp model. It uses a inverting summing amp to sum the Normal and Bass inputs. Reducing the MV or MV Trim will simulate the lower gain. To see our data use policy, opt out, or contact us please view our. They're much brighter so I turn the treble down quite a bit. Personally I think the AC20 is a better amp. I based the model on information I've collected over the years about the mods that were done. Clean to "Cinammon Girl" with the volume knob. This is the amp used on Dire Straits eponymous album. One sounds amazing, the other not so much. You can try increasing the Variac. The Axe-Fx triode models incorporate feedback so if there is a virtual cathode cap the stage is less linear in addition to having more gain. As you increase the Master the highs get muffled. When mounted in a typical cab the resonance will be in the low 70s. Everything on 7. This particular model is based on Keith Urbans #1. A Deluxe Reverb breaks up easily since it has 6V6 power tubes. The V1 and V2 are based on Mark Day's BE100. The Axe-Fx model of the JMP-1 is "better" in the sense that the tone controls control the tone stack rather than a graphic EQ. With every aspect of the amp being so carefully checked, theres little you could find wrong upon receiving your amp. The corner frequency is around 30 Hz. We earn a commission if you make a purchase, at no additional cost to you. ", "AC-30's have a poorly designed cathode follower. ", (Class A) "Turn up Power Tube Grid Bias. QA on Friedman solder joints is pretty terrible from what I hear. It's got some different component values than the Leeds which gives a different vibe. Another thing to try is to increase the Grid Clipping value which will add a little headroom. If you turn off Bright you're effectively clipping the bright cap. ", (Cygnus) "Carvin Legacy 100.
