We used Sapele for the body, Honduran mahogany and Wenge for the neck, and Indian Rosewood for the fingerboard. Ryan at Sage Guitars finishes the OBS series because in addition to being a great bass and guitar builder, he can rock a super thin but tough finish like nobody's business.
Owens' request lead me into my guitar building past as a builder for Satch, so we aerofoiled the MDM shape and created a platform for the bridge so it would look cool.
The EQ features a "12 points modded Keeley" TS9. Both the TS9 and the OBS are completely by-passable, and there's a routing switch that allows the Nordstrand series DC pickups to go directly to the TS9, or to the passive circuit with the OBP3 adjunct.
Funkfaker played Tim Lefebvre's OBS5. We just outfitted it with Nordstrand enamel wound 70's style pickups and did some mods on it, good to see real players can appreciate a shorty with a low B.
They're not cheap, but they fit in a standard guitar gig bag which is cool if you have to fly with it.
