Korg PS3300 (early model), Roland System700 and two Electrocomp 400 Sequencer at The Synth Sanctuary Recording Studio in New York City, all refurbished by us. We're looking to buy or trade for a full System 700 and a later model PS-3300 - please email us if you know where we can find either of these. It's ok if they're broken - we refurbish them.
