This M-Audio Black Box Guitar / Mic Interface (Needs Service) it powers up and display shows all is functional, but it doesn't seem to pass signal (to headphones) We did not connect it to a computer, so it may be fine. We just don't know. Selling it as is no return or refund.

Reverb "Poor" Poor condition items have clear functional problems that will generally require repair. Examples of items in Poor condition include a guitar in which the action is too high to be playable and a keyboard with lots of broken keys.
