Leyland Pedals Squarewave trem w/ mods for low pass and fuzz

Hi everyone
I recently built a modified version of a circuit designed by Leyland Pedals that they gave away for free. It is a squarewave tremolo, and I thought it could do other things as well, so with some help and advice from the nice people at the DIYStompboxes.com forum we added two low pass tremolo settings, two speed settings and of course a fuzz to make it into a fuzz tremolo :)If that sounds interesting you can watch the demo my son made while I talk about the circuit:


It's a simple build (as long as you don't try to squeeze it into a very small enclosure) and has a sound all of its own.

Links to the schematic / vero are in the description of the video

Thanks Chank. I had a lot of problems with the sound in the video - it sounds fine on my PC, but Youtube screwed about with it a lot, so I tried to learn how to deal with something called LUFS to fix it; not sure how it sounds - on my speakers the start of it seems very quiet... but it might just be my shoddy hearing. Thanks for watching it :)

Thanks for leeting me know! My hearing aids have had to go back to the factory for repairs and I've got a temporary pair to use but they don't sound right... even my guitar sounds wrong :( I can't wait to get them back. Hopefully this video will sound better when my ears are back online! Look after your hearing folks, you'll miss it when it goes.
