Both in mint condition. So the output impedance is lower. Otherwise it's a shrill mess. Check Price This amp was removed when the new MKII models were added and firmware updated. The best you can do is turn Bass and Treble to zero and Mid all the way up. Mesa knew this and the Lead 2 modes on the Triaxis all had the treble shift engaged by default. Not sure why they did it that way but it is what it is. The OD-2 is not the best amp for those tones, I totally agree with you, but a Dumble or clone doesn't really do fast dampened power chords like the OD-2 will do either. You have the Drive at 10 which means your power amp is at full blast. Turn it down and you are actually boosting bass and reducing treble. Throw a boost or Zen drive on that, if you like", "The tone stack in the PAB models is a neutral tone stack which is the same as lifting the ground. I would say it's a very functional layout and fair job, but I miss some attention to detail I can see in other similar priced amps (Germino, Metropoulos). The models are based on the higher gain input (the "1" input). Jodie fell in love with the guitar at a young age, but has hit a lot of bumps in the road with her journey. ", "The power amp in a Rockerverb has very little negative feedback so it will boost the highs more than most power amps. If it is too bright, you can adjust the various tone controls and parameters to reduce the brightness to your tastes. If you want the Channel 1 sound with an Axe-Fx use the Brit JM45 Jump model and turn the Treble Drive knob all the way down. It's just my idea of what 80's hair metal might sound like. Incidentally, anyone have any Twin Sister gut-shots? The 2C and 2D models have lower output because of the Sat switch position. It can fill arenas and venues of any size and requires minimal handling for fantastic, on-the-spot results. Dave Friedman is an amp-whisperer to the stars. This causes lots of crossover distortion (papery buzz). For a better experience, please enable JavaScript in your browser before proceeding. All Rights Reserved. I put it back in. 5.0 for left position (default). The original Herbert is too dark, fuzzy, compressed and muddy IMO. This reduces the gain and acts as a sort of compressor. If you like the base Dumble sound but want a little more gain without the fuzziness of a Fuchs try the Carol-Ann models. Our contributors use and test each instrument, accessory, or service in their real lives and we never recommend anything we wouldn't use. Not sure why. It was modded by Roy Blankenship. After 7 the treble increases rapidly. I would say it's a very functional layout and fair job, but I miss some attention to detail I can see in other similar priced amps (Germino, Metropoulos). ", "All these amps have the same basic circuit with minor differences. Well to all those guys who bash Mesa amps, they have their own factory. It does require a bit more thought than just moving the pots as the ranges of those trimmers Dumble used is impractical when used as front panel controls (which they were not really intended to be). There are topology differences and the amps don't sound the same. ", "So I was testing the next beta and selected the AC-20. been wanting one for years, but I thought he wasn't making them any more. This is accomplished typically by putting a capacitor in parallel with the plate resistor(s) which rolls off around a few kHz. The Bright channel model is selected by turning on the Bright switch. ", "You don't need to crank the real amp to get a ton of overdrive. We have two JCM800s and this particular amp sounds way better than the regular one with the rocker type power switches. You can reduce it by turning on the Plate Suppressor diodes. Legend II is channel 3 from the Legacy 3. That's due to the cathode follower. Pink Taco (Direly immature.) Friedman amps are known for their phenomenal response and their ability to pick up every fine detail. So if you use a 16-ohm speaker you get more feedback (and much more bass) than if you use an 8-ohm speaker. Friedman probably realized this and that's why there's no bright cap on the BE as the BE is very similar to the Atomica. He's modded amps and built rack systems for everyone from Jerry Cantrell to Eddie Van Halen to Steve Stevens, and he's still the guy Slash calls to set up his pedalboard. Or in the case of an SLO100 it is intentional. We have chosen 5 Friedman amps to explore below, based on; popularity, top sellers with different retail prices, so that every reader can look further into a Friedman amp that applies to them. The AFD100 amp that Marshall produced years later (that was supposed to be a #34 copy) has nowhere near the amount of treble boost and has a huge snubber cap on the PI (which rolls off the treble). The model is MIMIC'd and is extremely accurate. I asked if it could be ported for Q3 as I was having a difficult time migrating to the updated firmware and retaining our earlier work. Our model is based on a 1981 2204 Master Volume JMP. . ", "The normal channel on a Vox would be closest to the Morgan. Coupled with the right cab the emulated model does a good job of representing the basic tonal signature of the amp". ", "Maybe the best clean model IMO. ", "The amp has a Hi Cut but it's labeled Brilliance. ", "This model is my interpretation of the ideal modern metal tone. My JJ could be made on the moon for all I care =D. Friedman has squeezed the iconic features of Cantrells flagship amp head, renowned for its exquisite high-gain tones, into an affordable and compact combo and with impressive results. For an amp designed to be pushed hard in to power tube overdrive, this should be omitted as all bets are off in the feedback loop when you hit the rails. ", "When you dime the controls and whack a big chord the sound "goes away" a bit just like the real amp and then comes back a bit later. 2.2 nF would mean less bass. Go up/down from there to get the desired power amp overdrive. When players talk about Friedman amps, the BE-100 is always at the top of the list. It can be switched in via relays which are controlled by the channel switches. Most issues I have seen involved the shipping company punting these amps around like footballs. The biggest change, IMO, was changing the PI resistors to 47K which gives you a little less gain in the PI. Iconic sound in a compact, manageable format. Switches: Bright, Mid (not modeled), Rock/Jazz (not modeled). The power amp then compresses the highs and the sound gets fatter. Dean Friedman Music Website. Just like with the actual amp. In fact all stages in a Dumble typically have an AC load-line that's different than the DC load-line due to the load resistance being significant in relation to the plate resistor. ", "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. The amp is much more abrupt since it uses linear taper (should use 'S'-taper). 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. No other amp has anywhere near the amount of treble boost. In 2017, Fridmann became the director for the Western New York Alumni Drum and Bugle Corps, where he plays the bass drum. The particular amp used for the models was John Petrucci's personal recording amp. The model is the Plexi version. Steve Stevens and Jerry Cantrell turn the bass way up too. They're relative to the particular model. ", "IMO the designs are poor because wait for it they exhibit a papery buzz. The Gear Page is the leading online community and marketplace for guitars, amps, pedals, effects and associated gear. It may not display this or other websites correctly. I've reduced the default for Quantum 2.03. We now have a 20th Anniversary Shiva (with KT88s) and the new models are based on that amp. It is one of the Harry Joyce, Hylight era models. Check Price With all controls at noon the tone stack is equivalent to the real amps fixed tone stack. Custom Fractal Audio model. In the actual amp the Treble control is re-purposed as a Negative Feedback control. The default bias point is based on Mullard ECC83 tubes. Sort of like a Fender preamp into a Marshall power amp. ", The new DC-30 model may have dethroned the mighty AC-20 as my favorite "Class A" model., "Dr. Z is the quintessential country amp. He gave up his role as a touring member of the band in 1993 to concentrate on producing other artists. This allows the most flexibility. Zero worries. To my ears (and my measurement equipment), the Axe-Fx models are spot-on. 7.02 for the Recto Master is ridiculous and will sound like crap. The loop send is taken right off the MV which means the output impedance is very high. Fixed bias is just that, the bias point is fixed so the amp doesn't shift into Class B operation when overdriven (not as much anyways, depends on the bias circuit, grid stoppers, etc.). In the past, having Friedman build or modify your amp required a certain level of notoriety, but now his sonic wizardry is available to everyday players. al. Single notes can form an almost perfect square wave which will sound like a synthesizer. To simulate this lower the negative feedback by 1/sqrt(2). The amp will sound tighter and clearer in the low mids. This is not a problem with our virtual amps though. For cleaner sounds it tends to be objectionable. Regularly give the amp a wipe over, with a damp soapy cloth, to prevent a build-up of mold or mildew. The Axe-Fx II modeling includes a variety of general purpose filters that I can place anywhere in the signal path. Adjust LF Res, Freq and Q to get desired response. A tiny change in the bias point can make a big difference. Crude. For example, on the normal channel of a Plexi most people turn the bass way down. ", "A DR is numbered 1-10 so 3 on a DR is around 2.2 on the Axe-Fx. This stage clips, because of all the local negative feedback, quite hard. Is that better? Tone stack effectively has fat switch on. ", "The Ruby Rocket is not the same as an actual Trainwreck Rocket. Friedman's designs are a bit odd in that he takes the feedback off the speaker jack rather than off a transformer tap. Don't be afraid to turn them way up or way down. Part of this is due to the tapers on the tone pots. If youre wanting a show-stopping guitar amp then the Buxom Betty is an expensive, but excellent choice. It's called a Rockerverb not a Metalverb. ", (about the MESA Rectifier) "Personally I hate the 39K resistor. A prime example are Bogner amps. In the virtual realm we can have lifted tone stacks that actually still work. That would allow a hotter bias with longer tube life at the expense of slightly less volume but JCM800s are ungodly loud anyways so", "Based on the Santiago #34 modifications. There is no right or wrong. All that is left then is the 2 nF cap. ", "The Hook Clean 1 is a Fender style tonestack which has a lot more insertion loss than the others. AC-30's are very sensitive to the tube type and part tolerances. You can un-mod the model by turning down the MV Trim to around 0.5. The biggest difference is in the behavior of the Presence Shift. David Melech Friedman (born August 8, 1958) is an American bankruptcy lawyer and the former United States Ambassador to Israel. ", "A typical Recto cabinet has a resonant frequency a little over 100 Hz. In later versions of the Boogies (TriAxis for example) they changed the taper so that noon was equivalent to 1 on earlier models because people are reticent to move controls very far from noon for some weird reason.". ", "Our take on the ultimate British-sounding amp. ", "The 1987x doesn't have the 0.68uF cap on the last triode. This particular amp is known for sounding big despite being relatively low power. Cathode caps are very common in tube amps. They just call it treble. ", (Class A) "Turn up Power Tube Grid Bias. Thanks to the Synergy Friedman HBE preamp module, the exact tone and feel of the HBE-boosted BE-100 can be at your fingertips. I should revise to not say that it is not terrible QA, but that bad cases slip through. Before I get to that, let me lay out my understanding of the Friedman hierarchy, if this is wrong, please correct me here. So it's a high-gain Dumble. That's due to the cathode follower. Not sure if you watched the video, but Dave says that the Runts (which are PCB) have less issues than the rest of his line. Lowering the Cathode Resistance reduces the crossover distortion as it keeps the amp in Class A operation longer but the tubes run hotter and don't last as long. Presumably this was done to counteract treble loss in the loop. 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. ", "An OD100 is the head version of a CAE 3+. It biases the stage much too cold for my tastes. Twin Sister (Oh, clever. It stays in climate controlled storage otherwise. The real amp has a more British overtone to it due to the fact I am British and I designed it. To get the most range out of this amp, experiment with Master Volume and listen how it interacts with low or high Drive settings, similar to the real amp. [7] Discography [ edit] As producer [ edit] References [ edit] This was requested by Metallica's engineers after the main IIC+ models were updated, and it's part of Metallica's live sound. turn the Mid, Treble and Presence way up; turn Norm Drive and Bass down a bit. Capable of producing many styles of music from blues to classic rock and heavy rock to metal by just adjusting the gain, master controls and new added switches. We earn a commission if you make a purchase, at no additional cost to you. ", "The circuit is slightly different than the original 5F1. The treble cap is still in the circuit path. Totally different model. Vibrato effect, a so-called "real vibrato", which actually pitch-shifted the guitar signal rather than just creating rhythmic volume fluctuations. The amp is modeled assuming a 16-ohm load. The newer amp is brighter and tighter. ", "It's not a super high gain amp. It's probably an SLO100 power amp too but I'd have to check. As you increase the MV the source resistance increases which decreases both of these things. Change the Bright Cap value to 1 nF to emulate B2. This model is unique in that it uses a Baxandall (sometimes called a "James") tone stack. For cleaner sounds it tends to be objectionable. [3] In 2001, Fridmann was included on MOJO's 100 Sonic Visionaries list and was described as "the Phil Spector of the Alt-Rock era". As you increase gain you want less bass into the distortion stages so the idea is you turn the bass down. ", "Brit Super model is based on the Marshall AFD100. Etc. All nasty and spitty and full of "artifacts". ", AC-30 Bright: Normal channel, Brilliance input, AC-30 Hot: Top Boost channel of AC30HW, in "Hot" mode (no Bass / Treble), AC-30 TB: Top Boost channel of AC30HW, in "Cool" mode, "Note that the particular AC-30 used for the model has this scratchy high end. ", "Note that the Orange Modern and Red Modern models have no negative feedback and therefore the Presence control is a Hi Cut control. Having listened to audio samples, this amp works well across the genres but particularly so for country and blues, although here it shows what it can do for Billy Idol, The Who, and David Bowie. I've debated changing the taper or adding a pad between the preamp and power amp but, in the end, I decided to keep things authentic. Pristine condition. There is no NFB in the Modern Red mode so the Depth knob won't do anything. Was hearing a lot of ghost notes compared to the old algorithm (in the debug build I can select between algorithms with a hidden parameter) and figured that couldn't be right. (IIC+), "On a Mark IV (at least on our reference amp) all three controls have a Log10A taper.
