The ToneStyler B-10 BASS TEN, G-10 GUITAR TEN, and the new mid-range  S-10 SPECIAL TEN (formerly "Custom Ten") are ten-position miniature capacitor array / decade selector switches, for electric guitars & basses with hi-Z passive magnetic pickups.  These unique custom tone controls feature eight contrasting capacitance circuits with uniform audio-taper spacing between tones, and the guaranteed quietest switching in this device class!
The SPECIAL TEN is a brand-new mid-range variation of our full-range ToneStyler GUITAR TEN. The reduced 8.2nF capacitance range focuses solely on mid-range, presence, and treble harmonics. Voiced to enhance the clean and overdrive tones from classic all-tube amplifiers, the SPECIAL TEN is essential for bridge pickups in both stage and studio applications.
At full clockwise rotation #10, true bypass is selected; in the adjacent #9 detent, "virtual tone pot loading" is selected, which exactly duplicates the subtle loading and treble reduction of a standard guitar or bass tone pot when turned to maximum clockwise brightness.  B-10 range: TRUE BYPASS to .100µF;  G-10 range: TRUE BYPASS to .022µF;  S-10 range: TRUE BYPASS to 8.2nF.
For use in guitars or basses with only one master volume control (PRS, Telecaster, Les Paul Jr, P-Bass) connect the shielded cable directly to the volume pot's input terminal. For Strats, connect one ToneStyler as a master, and reconnect the other tone pot also as a master.
In four-knob guitars or basses featuring two pickup volumes and two tone controls (Gibson SG, ES-335, Fender Thinline, RIC 4001), use one ToneStyler for either the bridge or the neck pickup (it will also control 'both pickups'), and leave the other tone knob as-is.  Or, upgrade with a pair of ToneStylers, for independent EQ control of each pickup.
100% passive analog circuity - no batteries - zero noise!  Includes mounting hardware and 1/2" hex nut driver.  Hand-made in the U.S.A.   MAP  $139
