"Here's the legendary Oberheim OB-X, 8 Voice.
The OB-X has Oberheim S.E.M. filters while subsequent OB synthesizers have Curtis ladder filters which have a somewhat different sound. The OB-X is purely Oberheim.
Fully functional, with only one exception. It doesn't seem to want to load patch data from tape in. The memory locations do work and hold patches though. There's a new battery in there too.
This is a temperature sensitive synth, let it warm up, and it is warm."
