TOP ROW BOTTOM ROW INPUT DRIVE – Also known as Drive, Volume, Gain, etc. It is the knob closest INPUT TRIM – A clean, linear gain applied at the input to the amp block that to the input jack. In many cases it has a bright cap so the frequency response adjusts the relative gain of the preamp.

TOP ROW BOTTOM ROW LOW RES FREQ/Q/RESONANCE – Guitar loudspeakers have a low-frequency XFORMER LOW/HIGH FREQ – These set the output transformer bandwidth. resonance, typically about 100 Hz. This shifts up slightly when the speaker XFORMER MATCH – One of the most powerful controls in the amp block. It is mounted in an enclosure and is typically lower for open back cabs.

TOP ROW BOTTOM ROW SUPPLY SAG – Controls power supply impedance. Higher settings simulate PREAMP SAG – OFF replicates the behavior of separate preamp and power higher power supply impedance, causing greater tube plate voltage (B+) amp. ON replicates the behavior of an integrated tube head or combo amp. “droop”...

TOP ROW BOTTOM ROW PRESENCE SHIFT – Only available on Mesa Boogie Mark IV’s with a “Pull Shift” on NEGATIVE FEEDBACK – Controls the amount of negative feedback in the power the Presence knob (USA LEAD and USA RHYTHM). When engaged, it normalizes amp.

TOP ROW BOTTOM ROW LOW CUT FREQ – Reduces the amount of low frequency (10-1000Hz) before the TONESTACK TYPE preamp input. Use this is to tighten up a tubby bass end. Somewhere between ACTIVE – Gives each tone control ±12 dB boost/cut making them more 10-150Hz is generally where it will sound best for standard guitar tones.

TOP ROW BOTTOM ROW TREMOLO FREQ/DEPTH (bias tremolo) – Works by varying the bias of the virtual INPUT SELECT – The Amp block processes audio in mono. This control power tubes, resulting in a particularly “organic” sound. Most importantly, determines how incoming stereo signals will be processed. the tremolo is “self-ducking”...

TOP ROW BOTTOM ROW CAB – Loads a cabinet impulse response (IR). The older FAS and RW cabs were MIC – Don’t feel that you have to add a mic unless you want to add EQ, which recorded with neutral mics. OH, Kalthallen, and the Mix/Producer Pack series is basically what you would be doing.
TOP ROW BOTTOM ROW PREAMP TYPE – Preamp simulation menu selections recreate the sound of PREAMP MODE – Selects either Economy or High Quality modes. In High overdriven channel strips, preamps, tapes, etc. Quality mode oversampling is employed to prevent aliasing but this results in higher CPU usage.

Volume then allows the user to control the volume of the amp. The Master Volume in the Axe-Fx II, as well as on real amps, is probably the singular most powerful control in the amp block. As the Master Volume is increased the virtual power amp begins to distort. The virtual power amp also begins to sag and all sorts of beautiful magic occurs.
