Tom Oberheim is know for creating some of the best analog synthesizers.

Oberheim synthesizers are known for the warmth and thickness of their

oscillators as well as their creamy smooth filters.

The classic Oberheim is the SEM. A beautiful synth. The OB-X and the

OB-Xa carried on the tradition of the Oberheim sound and finally the OB-8.

And then of course the Xpander and Matrix 12 were new machines with new powers.

Another design that Tom Oberheim developed was the Marion Systems MSR-2.

An amazing piece of analog gear in a single rack space.
