These don't come up all that often, but I don't need it anymore so here it is. Although it doesn't say it I'm pretty sure this is the TK model, with individual BMT pots. It uses your existing volume/blend pot(s). No jack or switch included. The pots are the original ones that came with it, all 3 are identical. They are not marked as to brand or resistance, only bearing the following marks: 400-072 0237/ In excellent shape, works fantastic. $115 shipped CONUS. Canadian sale a couple dollars more.
