Over on the longest ever surviving Dumble thread the discussion has shifted to Carlton's Valley Arts Strat and the integral mid boost. I remember playing a Clapton Strat that had this mid boost on the second half of the tone pot travel. Not a TBX which just sounds shrill to me. Can these be retrofitted to conventional Strats? Where would I find one by itself. This would be a very handy addition to my cover band guitar.
