It's a Roland SH-2000 monosynth. My headphones have a quarter inch adapter
so I just listened through line out (that's all there is).

I don't have an amp on hand right now, but the last time I hooked it up I
needed to turn the volume WAY up to hear anything.


As this is a 70's synth, you may have some resistors that have increased way
out of tolerance. Would be a good idea to check the electrolytic caps as
well on a unit this old.
