"Volume-Volume-Tone" / Three set-screw knobs

ToneStyler - Duo Six -

-Simply the best drop-in replacement for your ineffective & dull tone pot.  Invisibly installs in minutes using your original knobs, without any modification to the instrument.  Precisely cut treble while retaining midrange resonance and rich harmonics.

The DUO SIX model is perfect for use with two volume knobs.  Importantly, by properly-connecting dual tone circuits directly to the pickups, "pre-volume", the DUO SIX solves Fender's original "post-volume" tone pot wiring design error as seen in all J-Basses made after 1962.  No more "mud tone" when the dual volumes are not set to maximum loudness!

Optimize your tone before your output passes through pedalboards, direct boxes, amplifiers, or microphones.  Recordings are vastly improved, and live performance tones are perfected.

100% passive analog circuitry increases the output and clarity of any guitar or bass with passive pickups.  No batteries - Zero noise!  Powerful and precise control of treble & mid frequencies is provided at last... and the tone pot's weak, muddy sound is completely eliminated!  Hand-made in the U.S.A.
