The FM9 offers the same amp modeling as the Axe-Fx III. The FM3 also provides the same amp modeling, but due to its lesser processing power, some features are not available. (FM3) "We removed all the superfluous stuff (bias tremolo, dynamic presence/depth, etc.) in order to get the core amp modeling to run on the slower processor."Ĭertain features were removed to allow the algorithms to run including the bias tremolo, input dynamics processing (.)." (comparing the FM3's amp modeling to the Axe-Fx III) "They are the same quality. (FM3) "The Axe-Fx III contains various algorithms that allow you to enhance the amp modeling that don't exist on a real amp. These were removed to allow the core amp modeling to run on the lower-powered processor." dynamic presence/depth, input dynamic processing, etc. "We model things that other products simply cannot as it requires more CPU power than available. The Axe-Fx III dedicates an entire 1GHz DSP to just amp modeling. And this DSP is 2-4x more powerful clock for clock than typical DSPs. We even model esoteric things like the bias excursion in the phase inverter. Many that I can't talk about because they are secrets." There's dozens of other little things like that. The same applied to the earlier hardware generations (AX8 vs Axe-Fx II).Īll current amp models are listed on the Amplifier models list page. Yek's Guide to the Fractal Audio Amp Models (PDF) provides additional in-depth information. Most amp models are showcased in the Factory presets page.įractal Audio's progressing modeling techniques are listed in the Firmware Release notes. While Fractal Audio's processors also provide state-of-the art digital effects, the amp modeling is the flagship feature. Why your amp doesn't sound like Fractal Audio's Amp modeling is part of the firmware but each generation of Fractal Audio's has a name: G3, Ares, Quantum, Cygnus. "The models in our products are based on our in-house reference amps. If a model doesn't sound like your version of that amp it won't sound like our reference amp either. The components used in tube amps are low-cost, consumer-grade parts. They typically have tolerances of 10% or more. Over time the value of these components drifts. If your amp is old chances are it doesn't sound like it did when it was new. All our old reference amps are given a thorough checkup prior to modeling with any out-of-tolerance parts replaced.Ī typical consumer potentiometer has a tolerance of up to +/- 20%. That's huge and that's end-to-end accuracy. On top of that the midpoint accuracy can be another +/- 20%. So if you have a 1M pot it could be as low as 800K. If it's linear it's midpoint should be 400K but could be as low as 360K. Now your 1M pot that should be 500K at halfway is only 360K. Potentiometers come in a variety of tapers: linear, 30A, 20A, 10A, etc. 30A) denotes the value of the pot at mid rotation. For example a 1M, 10A pot would be 10% of its value at "noon", or 100K. Manufacturers are constantly changing the taper of the pots in their amps. Sometimes the designer changes the taper as customers are reticent to turn knobs much away from noon. Sometimes the manufacturer changes the taper due to availability concerns.
