( Due to people taking advantage of eBay / Reverb return policies; wanting to “try out and/or pilfer parts”  we can no longer take returns on used gear unless it arrives damaged. Sorry for this inconvenience. We test and guarantee all gear to be 100% working unless stated otherwise )

Come play this gear in our shop!
