Crumar Bit One

Released in 1984

The Bit One is a two-DCO 6-voice analog polysynth, somewhat similar in specs to the Roland Juno-106. But the Bit One has a velocity-sensitive keyboard, and the ability to split or layer two programs.

We stock both NEW and USED parts; all used electronic parts are tested and guaranteed working.

This listing reflects our current inventory and is updated in real time. If a part is shown as Out of Stock, we typically don't know when or if we might have it again - but click on the part for more info, and then you will be able to sign up for an alert when we do have it available again. By including out of stock parts in our listings, we hope to offer customers a more complete and useful resource.

We cannot diagnose repair issues by phone or email. For technical questions, we suggest posting on our Forums, where our techs - as well as other users - can offer help.
