The Digital Sound Processor’s 32 position Mode control allows you to instantly access the exact type of
effect you want - from classic reverberation to radical “backwards” sounds - for any of the preamp or channel
settings. The diagram below illustrates where each “family” of effects is located. Use this diagram along with the
table on the facing page to familiarize yourself with the locations of the many different sound effects possible
from your GT-80D.
The setting of the Mode Control will determine the type of effect for whichever preamp/channel combination
the amp is set to at the time you adjust the Mode control. Once set, the GT-80D’s non-volatile memory retains the
setting until you reset it.
Example: Plug in your guitar and turn on the amplifier. Set Channel Select to Clean, Tube/Solid State Select
to Tube. Now set the Mode Control to “12” (medium gated reverb). Strike a chord on your guitar and listen to the
sound of the effect. Press in the Channel Select switch to choose the Overdrive Channel, then set the Mode
Control to 26 (large hard surface echo). Strike a chord and listen to the results. Now press Select again to get back
to the Clean Channel and strike a chord - even though you haven’t changed the setting of the Mode Control, the
amplifier “remembered” that you had programmed in setting “12” and kept the effect as you left it.
Theres more: When a Reverb footswitch is used, you can program each of the four channel/preamp combi-
nations with two Mode settings. If you want to control reverb on/off with the footswitch, for example, set the Mode
to “0” (bypass), hit the footswitch and set Mode to “5” (large bright hall). Now you have the ability to switch the
reverb on and off with the footswitch.
With the footswitch you have a choice of two reverb settings for each of the four preamp/channel combina-
tions, for the most flexibility and versatility possible!
