CHx: Selects your channel and GAINx , BRIGHT switch, and VOLx.

GAINx: Overall gain control.

BRIGHT: 3 way high frequency boost that becomes less active as GAINx control is increased.

VOLx: Channel volume control to balance output between other channels. It affects the SEND levels of the FX LOOP. 

TSS: 3 way switch that shifts the frequency point of the tone stack to better match the amplifier to different speaker types and room sizes. 

BASS: Passive interactive low frequency equalization for CHx.

MIDDLE: Passive interactive midrange frequency equalization for CHx.

TREBLE: Passive interactive high frequency equalization for CHx. 

DEPTH: Power amp control of low frequency interaction between amplifier and speakers. Dedicated to row of controls for CHx selected. 

PRESENCE: Power amp control of high frequency variable feedback. Dedicated to row of controls for CHx selected. 

TIPS: For the Clean Channels 1 and 2, obviously keeping the gains lower and bringing up the channel volumes will yield the clean tones and vice versa 
for dirty tones. For channels 3 to 6, make sure to have the channel volumes 2-3 o'clock or more to have the correct amount of body on the tone. Then 
just make the channel volume adjustments to balance the loudness between the channels. All the channel volumes are pre FX loop so after you balance 
all the loudness levels between all the channels, you only have to set your loop up once. After that when going to gigs or rehearsals, only the overall 
master volumes have to be adjusted as everything else stays as is.
