"Volume-Volume-Tone" / Three push-on knobs

ToneStyler - Duo Six -

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

The DUO SIX model is tonally-perfect for use alongside two push-on volume knobs, but it requires a contrasting USA set-screw knob - it will not fit your push-on tone knob.

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.
