Stellartone ToneStyler installation

The ToneStyler BASS TEN and GUITAR TEN have 1/2" length x 3/8"-32 dia USA threaded bushings, and 24-fine-spline split-shaft USA tips, for mounting through ≤3/8” surfaces, and using either USA push-on knobs or USA/metric set-screw knobs.

The ToneStyler DUO SIX has a 5/16" length x 3/8"-32 dia USA bushing, and a 1/4" USA solid-shaft tip, for mounting through        ≤3/16” surfaces, and exclusively using 1/4” hole USA set-screw knobs (no push-on knobs!)

 

The ToneStyler BASS TEN & GUITAR TEN models are compatible in two-knob “volume-tone” and four-knob “volume-tone-volume-tone” instruments:

 In single-pickup instruments (P-Bass, Les Paul Jr), solder the RED wire to the pickup’s HOT output wire, where it is presently soldered to the input lug of the volume pot.

In two-pickup instruments with two knobs (Tele) or three “volume-tone-tone” knobs (Strat), solder the RED wire to the input lug of the volume pot, where the pickup selector switch’s HOT output wire is presently soldered.

In two-pickup instruments with four knobs (Les Paul), replace one or both tone pots. Solder each ToneStyler’s RED wire to the input lug of each volume pot, where each pickup’s HOT output wire is presently soldered.  If replacing only one tone pot, we suggest the bridge tone pot.  As an economical option, replace your neck pickup’s tone pot with a push-pull pot; the switch allows your bridge pickup ToneStyler to select either pickup - see the Stellartone website for wiring instructions.

Never connect the RED ToneStyler wire to the output lug of ANY volume pot… and never connect it to the output jack of your instrument!  This doesn't work.

Each ToneStyler cable contains one CLEAR "floating ground" wire.  This important wire completes the ToneStyler's internal tone circuit; it doesn't provide any hum or noise prevention. The CLEAR floating ground wire allows for optional installations, such as in instruments featuring customized series/parallel/phase switching.  Each CLEAR floating ground wire must be soldered to the same connection point where the pickup coil's neutral wire is soldered, or the ToneStyler will not function.

Each ToneStyler cable contains one stranded copper shield wire, which is electrically-common to the metal casing and mounting bushing… and after installation, connects to the guitar's conductive mounting surface.  For hum and noise prevention, solder the stranded copper shield wire to the pickup cable's ground wire, which is often found soldered to a metal volume pot case.

For typical installations (no custom switching), separate connection points for the CLEAR and stranded copper shield wires are unnecessary; only one combined ground point is required.  Simply twist & solder the ToneStyler's CLEAR and stranded copper shield ground wires together, and solder both wires to the pickup wire's ground point… exactly where it's presently soldered in your bass or guitar.

 

The ToneStyler DUO SIX is compatible in three-knob instruments with two volume knobs but one only master tone knob  plus two-knob & four-knob instruments:

 In three-knob “volume-volume-tone” instruments, such as Fender’s Jazz Bass, Gibson’s Explorer & Flying V, as well as in most Gretsch models, one “master” tone pot has been improperly-connected “post-volume pot”.  This tone control receives a weak signal whenever both volume knobs are not set to maximum loudness… causing a thin & muddy tone.  The solution is a DUO SIX, with its two independent cables properly-connected “pre-volume” to optimally control your two separate pickup signals at any volumes or blends.  No more “mud tone”!

Solder the DUO SIX’s two RED wires to the input lugs of the dual volume pots, where each pickup’s HOT output wires are presently soldered.  The deeper .047µF BLUE cable controls the neck pickup, and the warmer .022µF RED cable controls the bridge pickup.  For optimal performance and balanced output levels, the bridge pickup’s EQ range is voiced about one octave higher than the neck pickup’s EQ range.  See the instructions above for connecting the CLEAR and stranded shield wires.

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 only one… or both cables to the volume pot… the installer’s choice between four contrasting tone ranges is easily made:  .069µF (cables in parallel) .047µF (blue cable) .022µF (red cable) or .015µF (cables in series).  This versatility allows one DUO SIX to be shared and transferred within a variety of guitars and basses, as may be required for recording or live performances.   See the Stellartone website for series & parallel cable wiring instructions.
