Functional Condition — IMPORTANT DISCLOSURE

Neither component has undergone verified functional testing for this sale.

The correct power supplies and MIDI cables were unavailable, so proper testing could not be completed. This does not necessarily indicate a defect; operation simply could not be verified.

We cannot confirm whether either unit powers on, whether the Ground Control Pro display and footswitches operate or transmit MIDI commands, whether the GCX responds to MIDI commands or has functioning audio loops, whether phantom power works, or whether the two units operate together correctly.

They are being offered as untested equipment that may function normally or require service or repair. No claim of successful operation is made. The conservative Reverb Fair category reflects unverified functionality, not a diagnosed defect.

Please review Reverb’s current refund and return policies before purchasing. Buyers may contact us with questions.

Power Requirements & Connection

GCX Guitar Audio Switcher:

- Requires a compatible 9VAC power supply

- Four-pin DIN power connection

- Original-specification 9VAC / 1A supply recommended

- Confirm connector wiring and compatibility with Voodoo Lab before use

Ground Control Pro:

- Supports independent operation with a compatible 9VAC adapter

- Can receive phantom power from the GCX through a fully wired five-pin MIDI cable
