Roland GKP-4 GK parallel box with GK cable. If you’re reading this, you pretty certainly know what this bit of kit does and is for. It came to me as part of a big lot of processors and effects and I’ve no need for it, so selling on. Appears to be in good order and comes with the cable as shown. Cable is approx 1m in length. Drop me a line if you have any questions and I’ll do my best to answer.
