• DUO SIX
  
  The ToneStyler DUO SIX is a six-position EQ control featuring two cables & two independent tone circuits, operated simultaneously using one standard tone knob. The deeper neck pickup's circuit ranges from TRUE BYPASS to .047µF; the brighter bridge pickup's circuit ranges from TRUE BYPASS to .022µF.
  The bright tonality of TRUE BYPASS switch position #6 may be optionally-configured for a warmer "virtual tone pot loading," by adding the included parts to your volume pot's terminals.
  
  New features for 2021: Within these traditional tone pot capacitor ranges, the dual circuits have been precisely re-voiced from bright to dark, in five complementary audio-taper tone steps. This refinement now allows both cables to be connected together in parallel to create a single-circuit ToneStyler SUB-BASS control, ranging way down to .069µF… or alternately, connected together in series to create a single-circuit ToneStyler MID-RANGE control, adjusting down to only .015µF. These two optional EQ ranges enjoy the same uniform audio-taper tone spacing per step, as when only one cable is used.
  
  The DUO SIX is 100% compatible with passive high-impedance pickup basses that have three-knob "volume-volume-tone" controls, such as Fender's J-Bass. Use one Duo Six unit per two volume controls.
  
  Alternately, the DUO SIX may be installed in a single-volume-knob bass or guitar, such as Fender’s P-Bass and Telecaster. By connecting one or both cables to the volume pot, the installer’s choice between four contrasting tone ranges is easily made: .069µF .047µF .022µF or .015µF. This versatility allows one DUO SIX to be shared and transferred within a variety of guitars and basses with many different control plans, as may be required for recording or live performances.
  
  100% passive analog circuity - no batteries - zero noise! Made in U.S.A.
  
  Bass Ten
  
  The BASS TEN is a ten-position EQ control featuring eight hi-cut / mid-cut resonance filters, plus a "virtual tone pot" loading circuit and true bypass. Maximum capacitance: .100µF. 
  
  The B-10 is compatible with passive high-impedance basses with two "volume-tone" knobs (P-Bass), or four "volume-tone-volume-tone" knobs (RIC). Use one B-10 per volume control.
  
  * The Bass Ten is NOT FOR "Volume-Volume-Tone", J-Bass, or T-Bird (need to use Duo Six)*
  * Does NOT FIT Epiphone 18-coarse-spline metric push-on knobs.*
