I have an original Yamaha DX7 synth that I scored new in Feb 1987. I'm pretty sure Brent used one at one time or another during the mid 80s. It's been sitting around or the last 20+ years or so not doing too much - Thought I would offer it up here first if you guys know anyone who maybe interested. $300 with the 2 extra sound cartridges it came with. Local to Philly or within 100 miles or so. Probably better off w a new Nord or even Casio - but if you are looking for that FM synth sound this is it.
