Ok so I reall need to go back and mark up all the changes that I did to this poor poor pedal. I have yet to do some component upgrades (that is some caps are still the crummy types that ship with the unit - and could marginally improve the sound) I changed the tone stack, the RC filter for the clipping diodes, all the input and output caps, ad stilla resistor here and there. it's a wonderfully cheap pedal and this mod will run you less than $5 in parts. My previous mod still lacked considerable bass. Now I've squeezed all i could possibly get out of it. In fact the only major change I could make would be to change the IC but I'd need some kind of adapter for that. here's the clip http://www.filefreak.com/pfiles/70163/ds1%20mod%20bass.mp3 i added a little reverb because I was feeling saucy.
