I'm trying to place an order for some parts i need for an overdrive pedal i'm making, but i can't find the following:
IC1-4558 (it's an IC)
Ra-100 (TS-808 part)
Rb-10k (TS-808 part)

or if you know of where i could find these:
IC1-4558 (same part as before, an IC)
Ra-470 (TS-9 part)
Rb-100k (TS-9 part)

i also can't find a 51 pF capacitor anywhere

you're building off of Tonepad's design, aren't you? That's what I did with mine!

In anycase, I never found a 51pfu cap, either, I can't remember was value I subbed in, though. The RA/RB are just resistors, A/B depending on what design you build. They're just straight up resistors.

The IC, I got the 4558 from Small Bear, but I can't seem to find it on their anymore.

nevermind, they've got it: http://www.smallbearelec.com/Detail.bok?no=213

The IC is in short form...its JRC4558 or RC4558
RA, is 100ohms, 100R all the same
RB, you cant find a 10K resistor???

51pF caps can be hard to find. The value of that cap isn't all that important. 47pF will work fine. Its just a form of negative feedback to cut highs.

^ gotta put them in parrallel though.

bingo, I went with 47pF.
