Build the Small Clone circuit on this layout. The FET switching has been removed to use true bypassswitching. Layout shown with depth mod applied, see ‘schematic for depth switch’ for stock wiring.Pads A, B, C, D, E are for the stereo mod. Off board components except for the potentiometers are notshown on the layout. Trademarks are property of their owners.

Use Ra=4.7k and Rb=2.7k and wire a SPST switch likethis:

This mod is for changing the value of the 150pF capgoing to pin1 of CD4007. Use a SP4T rotary switchwired like this:

Use the pads on the main PCB and wire this circuit:

The Stereo Mod requires a separate board. The original small clone had a depth switch instead of thepotentiometer, this gave two depth options only. The layout provides pads for this mod, just follow theschematic for the depth switch. Trademarks are property of their owners.
