Good luck & have fun Benjy, but I forbid you let you spend more than 2 or 3 bucks on a single cap... I get my caps on either online or on eBay, from 'peace.love.music, & I load up on some old PIO Bumblebee's, & I buy low values like .0022 or .0027's, & they w/o fail measure between .005 & .007, tops. In a different tone circuit, maybe an .008,,, and when done right with the right match, I get this cocked wah wah effect!! It's fantastic!! I don't know why anyone would want or settle for the .022 & 047's that come stock.... Who plays 'that' dark?!? A uselss sound,,, Start with a
.01, the tweak from there. What I've chosen to do is not so uncommon, & is used my more pros than you can imagine. You can also piggyback then in series or parallel for tweaking,,, BUT with the reverse effect than when you jp resistors,,, remember that!!
peace & have fun!!
