BOM is for Silver Pony version.

Gold version values shown in

blue

If using a 7660 for IC3 you need one with an

S suffix. This ensures it will operate at a

frequency high enough to be inaudible.

*There are a few value substitutions we

recommend - see next page for details.

**R28 is the current limiter for the LED. This

is now located on the footswitch

daughterboard and is marked ‘CLR’.
