Travis Bean 500 #12

Dec 31, 1976 - Sept 3,1977

The Jerry devised Onboard Effects Loop was first used on Dec 31, 1976. The OBEL 1.0 is a Switchcraft 14b switched TRS jack. It's inserted after the pickup selector switches before the volume potentiometer. The 14b's switches are wired together so when the effects plug is removed they tie together and allow the guitar circuit to stay intact without the effects loop plug inserted(layout and schematic at bottom of page).

Note: No Blaster Preamp in this first incarnation of the effects loop, the Mutrons bypassed state became the line driver when an effect was not in use.

Travis Bean 1000a #51 & #715

Jerry's TB1000A #51 was broken beyond repair when someone tried to mount a third middle pickup. It was sent back to the Travis Bean Factory for repairs, but they ended up just sending him a stock new one, serial #715. Jerry wanted the new one to have TB single coil pickups, so, #715 was delivered with Travis Bean Single coils centered & epoxied into a TB humbucker cover used as a mold. The results left the Travis Bean humbucker stamp still in the epoxy form when removed from the mold. Here are shots of what #51 body looks like today and a shot of #715's Epoxied Single Coils.
