Digital Music Corp. Voodoo Labs GCX Guitar Audio Switcher Customized #37890

Availability: In stock




BRAND: Digital Music Corp. / Voodoo Labs

MODEL: GCX Guitar Audio Switcher

FUNCTION: Guitar Signal Routing Interface

PRODUCT DESCRIPTION: This listing is for a Digital Music Corp. Voodoo Labs GCX Guitar Audio Switcher Interface. Please note that this has been customized:

This unit has a custom chip that disables loops 3-8. If you buy a standard chip and install it the unit SHOULD be fully functioning.In other words, I don’t think the unit is “broken” it’s just customized to only work a specific way. On older units if you wanted to use more than one, DMC had to install a chip to designate each successive unit in the chain. Since then they’ve updated firmware in the ground control units so that this is not necessary anymore and thus any unit can be place anywhere you want without having to have the signal chain being essentially hardwired via chip upgrade. In any case, this unit also has some upgrade/potential issue where only 2 loops work and the rest are disabled. Would need a new chip to undo all that.
