Vintage original 4-button foot switch for the Acoustic Control Corp model 330 amplifier head. Probably the rarest of all Acoustic footswitch of any kind. The cable-end connector is the proper Jones plug for the 330. Provides foot control of the 330's A&B preamp channels and for turning on/off the Reverb, Master Volume, and Graphic EQ.
Only with a footswitch can you select. "Channel-B Only" in switched mode and completely turn off (bypass) the Graphic EQ on both channels simultaneously. Pedal has normal wear from age/use, please see pictures. Can also be used with certain other 3rd Generation Acoustic amplifiers that use the Jones plug interface.
Since Acoustic always used the same plug pin number for a specific function regardless of model, this 330 pedal could also be used with single-channel models 124, 125, and 230 to control just Reverb, Master Volume and Graphic EQ with the 4th button (A/B) simply doing nothing. Similarly, it could be used with a two-channel model 320 to just control A/B Channel and Graphic EQ with the Reverb and Master Volume buttons doing nothing.
