This 1/4" jack is designed to accommodate most any guitar output signal. Input signal gain can be adjusted by the
GAIN controls on both the Ultra and Rhythm channels.
(2) Ultra Channel—Activation LED
This indicator illuminates when the Ultra channel is selected. Channel changing can also be accomplished by the 2-
position toggle switch (19) or the included footswitch. Each model comes with a different footswitch. Please read
the Footswitch section in this manual for operation.

type) and allows 15 dB of boost or cut.
(6) BODY

(peak/notch type) and allows 15 dB of boost or cut.
(7) EDGE
This control, on the Ultra channel, varies the high frequency response of the amplifier. It is an active control
(shelving type) and allows 15 dB of boost or cut.
