THIS GUITAR HAS SOPHISTICATED TONE CONTROL FUNCTIONS;
Which "require" charting them out for the most complete understanding of the different volume and tone controls for different pickups switch positins.

The tone on this guitar is accentuated between pickups by the OFF switch positions putting a small amount of volume (elevated volume floor) on pickups that are switched off; ....while the knobs that function as Tone rolloff (different knobs for different switch positions) do so by either rolling off the full volume range of a pickup OR only down to the elevated volume floor OR by rolling off the elevated volume floor;  AND by regulating signal through the filter capacitor like conventional guitar tone knobs.  The Master Volume knob always acts as a Volume control for all settings.

KNOBS / POTS LABEL ABBREVIATIONS USED ON THIS PAGE:

MV = Master Volume controls the volume of the selected pickups equally.

TV = Tone rolloff thru the filter capacitor AND rolloff of volume, for the effected pickup shown on the corresponding chart.

TV = Tone rolloff through the filter capacitor AND by rolloff of an elevated volume floor.

V = Volume rolloff only, for the effected pickup as shown on the corresponding chart.

T = Tone rolloff only, for the effected pickup as shown on the corresponding chart.

MT = Master Tone .....for all settings when it occurs in some switch positions.

X = No function at all.

NOTE:   .01mF, 047mF and .02mF are noted on the charts tone pots and refer to the value of the tone capacitors on each tone pot.  Higher capacitance allows more tone to roll-off to ground and therefore affords more bassier tones across the roll-off of the the neck pickup pot / knob, and more mid range tones across the roll-off of the middle pickup pot / knob, while the .02 cap on the bridge pickup pot retains more treble tone across that pot's roll-off.

( The charts are NOT electronic schematics; They are flow charts of the guitars controls functions ).


------------ oOo ------------
Each switch position sets different knobs for volume and tone control, but after you learn it it's a rather intuitional arrangement for such a sophisticated circuit / function design.  So the charts below are based upon switch positions.  You can click on this first row of icons to see the chart for that switch combination;  Or you can simply scroll down through the different switch positions and their knobs / pots functions.
