Questions (mostly) about wiring pots - First build

Alright, i'm now trying my first build. I've spent the last few days looking through schematics, reading books on electronics, browing mouser and rummaging through every radioshack drawer possible. I think I might be ready for actually trying a build now, I'm just having a few problems.

this is what my first build will be. I kinda spliced a circuit in half and put another one in there. It's going to be a mixture of a fuzz and a mid booster. The fuzz is the two parts on the outside, the mid-booster being the one on the inside. I have a few questions though...

1. This might be kind of a vague question but, Will this... Work? Is there anything noticeably wrong with it?

2. I would like to wire in a "tone pot" to control my mids, All the way back would be thin, scooped mids, and all the way forward would be mid-heavy awesomeness. How would I go about doing this? I have no idea where to even start on that.

3. I would like to do the same thing for a fuzz control knob. This fuzz was originally designed to not have any form of pots on it and be kinda like running two fuzzfaces at the same time. Where would I put the pot? What kind? How?

4. I'd also like a "volume' pot. I'm assuming I could just go ahead and wire it after the switch but before the rest of the circuit, letting it pass through and bleeding off the signal into the ground as I roll it back. Would this work? Would this give off a bad tone when not 100% open?

5. Wtf is a 500p and 15n capacitor? I've never heard of those in my life. Is R3 actually a tone pot on the mid boost also? I can't tell if that's just something on the line or if that was supposed to be a pot.

Sorry for all the questions, and I hope to become a regular on this site after I get some more building experience. I feel like my entire life is the pursuit of tone, and this will be a large step for me.

500p, or 500pf is 500 picofarads. often labeled 501  1000 pico's is 1n or 1 nanofarad or .001uf, So a 15n cap is 15 nanofarads, or 15000 pico farads or .015 uf.

Often these are labeled as 153  this means 15 wth 3  0's behind it or 15,000pf/

For example if you had a cap that was labeled 154 it would mean 15 with 4 0's behind it or 150,000pf, or 150n, or .15uf.

A cap marked 473 would be 47,000pf's, or 47n, or .047


It took me a while to get this as well try this link it should help. Good Luck.

Oooh thank you, That threw me through a loop. I guess I should have payed more attention years ago in Chemistry when they explained this stuff, lol. Thank you very much
