ULTRA VOLUME (12)
Controls the overall volume level of the channel. The final level adjustment should be made after the desired sound has been achieved.
ULTRA GAIN CONTROL (13)
Controls the input volume level of the channel.
ULTRA GAIN SWITCH (14)
Boosts the overall system gain of the Ultra channel. Depress to the “in” position to activate.
CRUNCH GAIN SWITCH (15)
Boosts the overall system gain of the Crunch channel. Depress to the “in” position to activate.
CRUNCH VOLUME (16)
Controls the overall volume level of the channel. The final level adjustment should be made after the desired sound has been achieved.
CRUNCH GAIN CONTROL (17)
Controls the input volume level of the channel.
HIGH, MID, & LOW EQ (18)
Passive tone controls that regulate the high, mid, and low frequencies.
BRIGHT SWITCH (19)
Provides a preset boost to treble frequencies. To activate, depress the switch to its “in” position. The bright function affects only the Clean channel.
