DEPTH 

– Boosts low frequencies from the power amp simulation by varying the negative feedback frequency 

response. The 

DEPTH

 control is set by default to an appropriate value when the amp 

TYPE

 is selected, but this 

setting may be overridden. 

MASTER

 – The almighty 

Master Volume

 is a very important control. It determines the amount of distortion 

contributed by the power amp simulator, and its setting is key to an amp’s sound. As the Master is turned up, 
the entire character of the amp will change. The tone controls will have less influence on the sound, and the 
sound will have more “bloom” and touch sensitivity. To prevent volume jumps when changing models, Virtual 
“master” settings don’t necessarily correspond to knob positions on the amp being modeled.  

With a little experimentation on your favorite Axe-Fx II amps, you will learn to appreciate the qualities of 
different 

DRIVE

 and 

MASTER

 settings and how to find the great tones offered by different combinations. 

 

If a real amp doesn’t have a Master, begin with the Axe-Fx 

MASTER

 at or close to maximum when using 

that 

TYPE

.  Lower settings can also be used, and can sometimes reduce “harshness.” 

 

For “Cranked Amp” sound, set the 

MASTER

 to  3 o’clock and then slowly bring the drive up until the 

desired tone is achieved. At high Master settings, less drive is usually required, especially for high-gain 
types. If the Master Volume is set high, reducing the drive control is usually required for “best” results.  

 

Amps designed for preamp distortion will typically sound better with the 

MASTER

 set low to prevent the 

tone becoming muddy or excessively noisy. This includes the USA Lead types, SOLO 100, and others. 

 

Amps with negative feedback (damping greater than zero) tend to have a “crunchier” power amp 
distortion, which can get “raspy” if driven too hard. You can experiment with the interactivity of 

DAMPING

 

(see 

Advanced Parameters

, below) and 

MASTER

 to achieve desired power amp distortion timbres. 

 

Setting 

SAG

 (see below) to zero will 

disable

 Power Amp simulation, at which point the 

MASTER

 becomes a 

simple level control with 40 dB of range. 

LEVEL

 –

 

This is a copy of the 

LEVEL

 control on the MIX page for easy volume adjustment without page-

flipping. It has no effect on the inherent sound of an amp. 

POWER AMP VOICING

 – Voices the amp to a variety of tonal styles, taking the guesswork out of mix 

engineering by automatically adjusting the overall tone. Choose “Neutral” for the raw amp sound or choose 
one of the other voicings for a quick “mix-ready” tone. 

Speaker Page 

These parameters shape the virtual speaker impedance curve and the resulting resonances in the virtual power 
amp. Amp- Speaker interaction causes an increase in power amplifier response at certain frequencies, affecting the 
tone. Note that the power amp frequency response will not equal the speaker impedance if the 

DAMPING

 is 

greater than 0. This is because negative feedback flattens the response curve.  

LF RESONANCE, LF RES FREQ, LF RES Q 

– Guitar loudspeakers have a low-frequency resonance, 

typically about 100 Hz. This shifts up slightly when the speaker is mounted in an enclosure. This resonance 
causes an increase in the power amplifier response due to the finite output impedance of the power amp.  

MID RESONANCE, MID RES FREQ, MID RES Q 

– While most speakers don’t have a third resonance, 

this parameter allows you to fine-tune the edge-of-breakup profile for “hyper-realistic” tones. For authentic 
response, set MID RES flat (0.00).
