Specifications

ToneStylers® utilize premium-quality musical instrument rotary switches custom-made made by Grayhill® USA. Our switches are mil-spec, sealed, moistureproof, shockproof, EMI/RFI shielded, and feature gold-plated terminals & shorting contacts for the lowest resistance & most quiet switching possible. Average life expectancy exceeds 100,000 operation cycles. Now available in: short or mid-length shaft versions to accommodate all mounting surface thicknesses; right-handed or left-handed operation; solid-tip or splined-tip actuators to accommodate set-screw or push-on knobs; three discrete contour ranges: BASS, GUITAR & CUSTOM.

We use C0G Class A miniature ceramic capacitors of mil-spec quality, which are non-microphonic, sealed, and shockproof. These premium-grade ceramic capacitors are the best performing and most stable type of miniature audio capacitor, and offer the smoothest & most desirable audio filtering qualities, making them the perfect choice for guitar tone control use. Used commercially in virtually all guitars and basses since 1959, ceramic capacitors replaced the oversized high-voltage paper & foil types used in radios, televisions and amplifiers, such as "Bumble Bee" and "Black Beauty" caps.

See our EQ Response Charts to view the equalization curves of the ToneStyler, compared to those of a standard tone pot.

2014 ToneStylers, common & optional features:

  • Hand-wired and manufactured in the USA by Stellartone
  • 100% pure analog high-impedance passive tone circuitry, with zero noise, distortion, compression or clipping
  • Heavy-duty sealed mil-spec rotary switches with gold contacts and terminals, made in the USA by Grayhill, Inc.
  • The traditional and popular "notched rotation" mechanical design, with SIX, TEN or ELEVEN SWITCH POSITIONS
  • Left-handed rotation available in the ELEVEN-position ToneStyler series
  • 30° rotary switch detent spacing matches standard 30° numeral spacing... as used on Gibson USA push-on top hat and speed knobs
  • The TEN and ELEVEN position ToneStylers now feature dual tone pot emulation circuits at full clockwise, to precisely duplicate the tonality of both 500kΩ and 250kΩ tone pots when set wide open "on 10". Based upon the ToneStyler version, these "virtual tone pot" loading circuits match standard 500kΩ and/or 250kΩ tone pots fitted with the popular tone capacitor values: .047μF (BASS), .022μF (GUITAR), or .010μF (CUSTOM). SIX-position ToneStylers feature only one tone pot loading circuit at full clockwise.
  • Solid-cast metalized polymer modules are now color-coded by EQ range: BLUE for BASS, GREEN for GUITAR, and RED for CUSTOM.
  • Molded-in color-coded low-capacitance shielded cables by Mogami
  • Designed for easy, drop-in replacement of any standard tone pot with a 3/8" diameter USA bushing; no modifications or routing required
  • Complete with mounting hardware and instructions
  • Not compatible with low-impedance, Piezo, or active (battery-powered) pickups

    DIMENSIONS

  • Mounting bushing diameter: 3/8"-32 [U.S.A. standard diameter - mounts through 3/8" diameter hole]
  • Mounting bushing lengths: 0.3" (~5/16") short length on solid-tip controls, or 1/2" mid-length on splined-tip controls
  • Splined-tip actuator: Stellartone's proprietary "solid-splined" plated bronze alloy tip omits the traditional "split-shaft" slot; 0.235" dia. x 0.375" tall 24-fine-spline U.S.A. tip for U.S.A. push-on knobs and 6mm metric set-screw knobs; for 1/4" U.S.A. set-screw knobs, add the supplied 1/4" brass sleeve; does NOT FIT 18-spline coarse push-on metric knobs, i.e. Epiphone
  • Solid-tip actuator: 1/4" dia. x 0.375" tall smooth round plated bronze alloy shaft with a "D flat", exclusively for 1/4" U.S.A. set-screw knobs; does NOT FIT any push-on knobs, or any 6mm metric hole set-screw knobs, i.e. Gretsch Electromatic
  • New compact cylindrical shape has the same 15/16" diameter (24mm) as a standard full-sized CTS potentiometer
  • Low-profile polymer module requires only 0.9" depth (23mm) inside the instrument's control compartment (typically 1" to 1.6" deep... check your clearance before installation)

    EQUALIZATION CURVE DATA

  • Nominal Roll-off Shoulder Contour: -5 dB over 4 Octaves
  • Nominal Roll-off Slope Contour: -7 dB per Octave
