GX-40C+/40D Amplifier

THE DSP SECTION (GX-40D only):

The DSP’s 32 position Mode control allows you to instantly access the exact type of effect you want – from classic rever- beration to radical “backwards sounds – for any of the Channel/Chorus combinations. The setting of the Mode control will determine the type of effect for whatever Channel/Chorus combination the amp is set to at the time you adjust the Mode con- trol. Once set, the GX-40D’s non-volitale memory retains the setting until you reset it.

EXAMPLE: Plug in your guitar and turn on the amplifier. Set Channel Select to the Clean channel. Now set the Mode con- trol to “12” (gated reverb, medium). Strike a chord on your guitar and listen to the sound of the effect. Press in the Channel switch to choose the Overdrive channel, then set the Mode control to “27” (large hard surface echo). Strike a chord and listen to the results. Now press the Channel switch 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.

THERE’S MORE: With the Channel Select and Chorus being switchable, you can program each of the four Channel/Chorus combinations with their own Mode settings. If you want to control Reverb on/off with the Chorus footswitch, for example, set the Mode to “0” (bypass), hit the footswitch and set Mode to “5” (large hall, bright). 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 channel selections, for the most flexibility and versatility possible!
