Multi-Voice Passive
Our Standard Electronics employ the passive Multi-Voice Tone Circuit with our custom-designed Dual Soapbar humbucking pickup set to achieve a more diverse range of tones than you can achieve with conventional tone controls. The Multi-Voice Tone Circuit is an advanced tone control with 2 mini-toggles that operate somewhat like a parametric EQ. The 3 position Filter type switch selects either a notch filter (cuts mid-range), bypass (center off - turns off tone circuit) or a low pass filter (rolls off high frequencies with a slight boost of mid frequencies). The Filter Frequency switch slects whether the Filter type effects higher or lower frequencies. The Filter Depth knob (like a conventional tone control) controls how much effect the voicing circuit will have. The 3rd mini-toggle is a Single Coil Tap for both pickups. The other conrols are master volume and pickup blend.

3-Band Active EQ.
This is the simpleist of our active electronic options. The 3-band active eq. is very effective allowing you to shape the sound with individual controls for bass, mid and treble. A 9 volt battery is required for powering the active electronics. A blend control lets you move between pickups and the bypass switch changes the electronics from active to passive.

Our Studio Active Electronics package is for the ultimate in versatility, this combines our passive Multi-Voice Tone Circuitry with our Live Active Electronics package. In addition, two 3-position mini-toggles provide series/parallel/single coil switching to achieve 3 unique voicings for each soapbar pickup. You can operate completely in active mode and passive circuitry or combine both passive and active circuitry.

1. Dual-concentric bass and treble controls with center detent: ring is bass, center knob is treble. Treble frequency is selectable inside the control cavity.
2. Active/Passive Bypass micro-mini switch

7. 3 position Filter Curve Selector for the MultiVoice Passive Voicing circuitry. Down it's a notch filter, pulling out midrange depending on the frequency selector and pickup combination and mode settings. Up it's a high-frequency roll-off filter with an emphasis in the upper midrange, again dependent upon pickup selection, frequency selector and pickup mode settings. Center position disconnects the MVP circuit.
8. Bridge pickup voicing mode selector 3 position switch: down is series humbucking mode (the standard way most pickups are wired), middle position is single coil, up is parallel humbucking mode.
