B+Unswitched
Custom EQ Control will produce a slight POP when switched on. To reduce this wire Battery + (Red) to “B+ Unswitched”- but only if using a switching jack.
Mini Tube Amp can produce amplifi ed sound to a 1/4” jack using SP+ and SP-, and still produce normal sound through JK+. DO NOT use common ground for signal and speaker on Mini Tube Amp. Trim pot adjust level of output distortion when cranked, clockwise for more.
Tube Driver can produce extreme levels of boost at max- so be careful!!
Multi Drive Trim Pot adjusts Dirty sound level only- Active Clean mode (Position 1) is ALWAYS unity gain. (No Boost)

All Circuits install in a similar manner
Find the wire that leads to your output jack. Cut this wire. The side that leads to the jack ALWAYS goes to the “out” of any circuit, the side that leads back to your pots ALWAYS goes to the “In” of any
circuit. We like to wrap the 9 volt battery in some foam, affi x with a rubber band and install in the control cavity.
