Installing the Taurus Tm-2 Bass Preamp in a Barker B1 Bass

Taurus is to be applauded for their creative thinking in the physical design of this unit.  This image shows the completed wiring!  Wow!  Their idea was the tape-like wire that shows as a red line.  This gray material, of multiple conductors, has plugs attached periodically.  These plug into the pots, in any order.  This gives you terrific flexibility when the cavity space is limited.

The Barker B1four cavity is roomy for three pots, adequate for for, cozy with five.  I could have added two more switches from the Taurus kit if there has been space.  That said, changing a pot for a switch is a simple, no solder process.  Amazing.

I chose the volume, pickup blend, treble, bass and mid pots.  The only soldering was the pickup leads, the output, and the switch.  I chose a button switch instead of the usual switched 1/4" jack.

Here's a shot including the Gotoh two-cell 9v battery box:
