I'm wanting to mod my TS5/808 in a new enclosure to add the Clean blend like on the Voodoo Lab "Sparkle Drive". I'm assuming that the knob is a pan pot between the buffered clipped and unclipped signals on a TS808 circuit going straight to the volume pot. Does anyone have one or know what value pot/components and where to tap into a TS circuit to add this circuit?
IIRC the signal is split off the first transistor stage, then it's mixed with two resistors (dual ganged pot) into a unity gain stage. The volume control is moved from a voltage divider off the TS tone control stage to another op-amp voltage gain stage.
