The ToneStyler® utilizes only premium-quality sixteen-position musical instrument rotary switches made exclusively for Stellartone® 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: medium or long shaft versions to accommodate all mounting surface thicknesses; right-handed or left-handed operation; solid-shaft or split-shaft actuator tips to accommodate set-screw or push-on knobs; notched or smooth rotation; three discrete contour ranges: ToneStyler STD., ToneStyler JAZZ, and ToneStyler BASS.
We use COG (NPO) miniature surface-mount 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 types, sometimes called "Bumble Bee" caps.
