Find the sound of old VOX 846 Wah Wah with this card.
A configuration switch J1 is mounted on the card:
In position 1 it allows direct replacement (without modification) and operates in this case without the output buffer.
In position 2 the output buffer is active, this requires a small modification of the wiring. You can contact the DOC to modify your pedal.
On a printed circuit developed by DOC MUSIC STATION and double-sided shielded to guarantee the best possible signal / noise ratio, audio components are installed (carbon resistors, Panasonnic SMF and Wima MKS capacitors, BC109 NOS gold pins transistors and an adjustment potentiometer. output volume (when used with the buffer).
The inductor is a Whipple Halo Wah inductor which is hand wound and reproduces the characteristics of old inductors. The printed circuit is designed to support other inductors (Halo, red fasel, yellow fasel ....).
