1: INPUT: Connect your guitar here using a shielded instrument cable.
OVERDRIVE Gains:
2: TUBE GAIN: This serves as the gain control for the Overdrive Channel's Tube preamp section, giving you con-
trol over the compression and overdrive characteristics of the GT-80DSP's input tubes. Use this control along with
the Overdrive Channel's volume control (#15) to create a wide variety of sounds at any volume level. (Some sug-
gested settings can be found on page 12.) With the control to the full-left position, no signal passes through. As
you bring the control towards center you increase the signal level and the tube compression, with maximum tube
distortion towards the full-right position.
3: OVERDRIVE LED: This LED glows red when the Overdrive Channel is chosen, and along with LED #14 gives
you a visual sign that the Overdrive gains, tone controls and volume control are active.
4: SOLID STATE GAIN: This serves as the gain control for the Overdrive channel's Solid Sate preamp section.
Use this control along with the Overdrive Channel's volume control (#15) to create a wide variety of sounds at any
volume level. (Some suggested settings can be found on page 13.) With the control to the full-left position, no sig-
nal passes through. As you bring the control towards center you increase the signal level and compression, reach-
ing maximum distortion in the full-right position.
5: CHANNEL: Select either the Overdrive channel (switch in the IN position) or the Clean Channel (switch OUT)
with this pushbutton switch. The channel indicator LEDs (#3 and 14 for Overdrive, #9 and 19 for Clean) work with
this switch as a visual guide.
NOTE: When a footswitch is connected to the Channel Select footswitch jack (see #29, rear panel) the front-panel
switch will have no control over which channel is selected.
6: TUBE/SOLID STATE: Select either the Tube preamp (switch IN) or the Solid State preamp (switch OUT) for
either channel with this pushbutton switch. The Tube LED (#7) works with this switch as a visual guide: it glows
when the tube section has been selected.
NOTE: When a footswitch is connected to the Channel Select footswitch jack (which also serves as the Tube/Solid
State select; see #29, rear panel) the front-panel switch will have no control over which preamp section is select-
ed.
7: TUBE LED: This tube-shaped symbol glows orange when the Tube preamp section is selected, giving you a
quick visual reference as to which preamp section is active.
CLEAN Gains:
8: TUBE GAIN: This serves as the gain control for the Clean Channel's Tube preamp section, giving you control
over the compression and overdrive characteristics of the GT-80D's preamp tube. Use this control along with the
Clean Channel's volume control (#20) to create a wide variety of sounds at any volume level. (Some suggested
settings can be found on pages 12 and 13.) With the control to the full-left position, no signal passes through. As
you bring the control towards center you increase the signal level and the tube compression, with a bluesy tube
crunch coming to life as you approach a setting of 8 and thicker tube distortion in the full-right position.
