FRONT PANEL FEATURES
LEFT TO RIGHT (Right to Left on head version)
“TUBE DRIVE" SWITCH — Selects either TUBE DRIVE (Channel 1), or CLEAN (Channel 2). Red LED
indicates Channel 1 is on. Footswitch jack insertion (rear panel) cancels the operation of this switch.
CH. 1 & 2 SWITCH — When this switch is in the "up" position, both channels may be paralleled and will
be heard together when the Tube Drive switch is set to the Tube Drive position (up). With Ch. 1 & 2
switch up and Tube Drive switch set for Clean channel (down), only the clean channel will be heard.
When Ch. 1 & 2 switch is in the "down" position, the Tube Drive switch will select separately between
Tube and Clean channels,
INPUT JACK — Extremely wide-range input allows plenty of headroom for all types of guitars.
TUBE DRIVE — Adjusts the amount of gain for overdrive tube. Careful attention has been given to pro-
duce the most overdrive/sustain possible without creating unnecessary noise and feedback.
RED LED — Indicates that the Tube Drive (Channel 1) has been selected.
TUBE MASTER — Adjusts the amount of output volume from the Tube Drive channel.
HI, MID, LO — Classic, passive 3-band E.Q. to enhance the ProValve 60's unique tonal response.
Frequencies: HI ........... 3.5 KHz (upper shelving)
MID......... 800 Hz (center)
LO.......... 150 Hz (lower shelving)
CLEAN GAIN — Adjusts gain level of clean channel. Classic, extremely warm and tubey tonality is pro-
duced. Lows are especially well-balanced.
HI, MID, LO — Identical operation and frequencies to Tube Drive (Channel 1), however the over-all
baseline E.Q. has been optimized for clean and rhythm styles.
REVERB — Adjusts amount of reverb signal is mixed into the output. Reverb can be cancelled anytime
by the footswitch, or by turning the control to "0."
STAND-BY — Turns on or off "B+" voltage to the power tubes. This enables the tubes to remain warm
while disabling the power output.
POWER — Supplies main power to the amp. Be certain that the proper voltage is supplied to the amp.
The proper voltage for your unit is indicated just below the fuse holder on the rear panel.
