For mine I took an additional wire from the gain pot to a mix with Point e. I used a dual pot 100K to mix. The pot values may not be optimal - it just reflects what I had around - experiment with different values.
This is from memory! looking at the pdf from maplin
I take out R10 and have my guitar in join at s of r10 so basically it feeds into IC2. Take speaker connection x1-2 to pin1 of 100K pot (pin3 of pot to gnd) pin2 of pot where connection 1 of the mic would be if I had put that in. OUt put for the amp comes from point E of where R10 would be.
Nice job, a question could you send the schematic diagram or detailed discription of how exactly this is wired.And would the velleman kit that uses the ht8950a chip also work?
@scottsober1 I don't know the velleman circuit - I havn't examined their circuit in detail but it looks like it has the same parts - ht8950 and an lm386 opamp. It has an additional mic sensitivity control My gut feel is that you could do something similar.
Thanks for the info on this effects box. I plan on building one to run my electric guitar through for some "Robot" style vibe. What's nice about getting the kit is that it isn't covered in mystery goop, so modding really shouldn't be a large undertaking. It would be cool to try this box through my feedback looper pedal.
sounds kooool

Great post! I've been wanting to try out that kit for some time as a guitar stompbox. What are the values on the 2 pots?

Quick question: what are the values on the MIX and GAIN pots?
