Product Description

Oberheim OB-X with Midi for sale.

Has a filter modification which is very useful.

Information from the owner on this mod:
This OBX is an 8 voice model and it also has a fantastic mod that taps out all the other filter modes that are already on the voice boards (much like the original sem and 4/8 voice) but not used: Band Pand and High pass.. it has a three way knob on the pitch bend / mod wheel section that toggles between the modes. This mod does not in any way alter the sound of the OBX... in Low pass mode it sounds exactly like any other OBX, but now you also have the benefit of High pass and Band pass modes which is really great.

Previous service work included:
