# Oberheim OB-SX
“Hello… Up for auction is my Oberheim OBSX. It is the original Black and Gray version. Upgraded to 56 patches at some point. It is a SIX voice version. As you can see from the pics. The cosmetics are in very, very good condition for it’s age, no dents, scratches etc. All the LED’s, Inputs and Outputs, Levers, Keys etc work as they should. I am selling this incredibly fat sounding Oberheim because we have an ongoing major upgrade to our studio. This will help fund some new recording gear purchases. Otherwise, i’d never let this baby go. It does sound warm, fat, sweet, and huge! It comes loaded with ALL SIX voice cards, the max offered on this model. All the voice cards work, and three were refurbished my an oberheim tech several months ago, New Trimmers were installed on those three cards. One of the old cards can be a little off tune wise, but as directed by the original manual, upon power up, press the AUTO button to tune all voice cards. All cards work, sound and tune as they should, but I suggest a voice calibration after shipment as trimmers can drift in transit. Tuning the voice trimmers is very easy and I can supply schematics on the trimmers if you request it. The Keybed works perfect, all the keys trigger with no issues. Due to the age of this synth, This is sold as is, no returns, for any reason. I tested this OBSX at length this morning. It is in the condition I have listed above. Another great feature is you can press the UNISON button and play this baby as a KILLER fat sounding mono synth to which it sounds massive! It’s kinda like having an SEM mono synth.” Link
