We have a NEW Design BMT circuit layout with a Concentric Bass/Treble Pot. This BMT uses 4 instead of 5 knobs. The 5th hole is for a Top Jack instead of the usual Side Jack. Series/Parallel Switches will be added as well to this new BT/BMT Version. The new BMT Concentric Circuit will be available on BSR models as well.
For other Non-Smith Bass owners, the Pots are all on separate Circuit Boards so the Hole Layout does not have to be exactly as on a Smith Bass for the Circuit to Fit. This can be sold with a Side Jack as well.
