I'm an amateur guitarist, self proclaimed nerd. Mix the two and you get a pedal builder eventually. I started making my own pedals a couple of years ago with the idea of replacing all my purchased ones with self made. Thought I'd start sharing the adventure as a pay forward as most of my makings are from the help and mix of ideas from others that give their time to do so. Over time i hope to cover a few things I've learnt along the way and share some of the pedals I come up with.

Memory Man with a PT2399
So I finished a couple Dirtbabies lately, one for a friend and one
for me.
It's simply the BEST PT2399 delay I've built.
I
changed C10 (1,5nf instead of 1nf) and C12 (150nf instead of 100nf)
for less noise and a very slightly darker tone (still quite
bright!)
R4 is about 30k (raising C12 raised the volume also),
and R35 is 56k. C14 is a 47uf tantalum (I read in the notes from
valvewizard that using a tantalum in that place was better, so I keep
doing it with every PT2399 circuit I build)
The first
opamp is a BB OPA2134 and the second one is a OP275.
I
added a charge pump to run it at 18v (much better in my opinion!) and
also added a couple things:
- a tone switch that adds another
1,5nf in parallel with C10 for a much darker delay
- a slam
footswitch with internal trimpot accessible from behind, to decide
how fast it ramps towards oscillation.
I t's
seriously not a difficult build, as long as you take your time to
plan everything well.
I'd recommend to socket all opamps
and PT2399 of course, but also :
R4 (feedback resistor. In mine,
33k)
R35 (mod rate. In mine 56k)
R37 (mod depth. Kept it
stock in mine)
C8 (just in case, cf build doc. Stock in mine)
C9
and C10 (in mine C10 is 1,5nf, helps with the noise, though it cuts a
tiny amount of treble response. Still bright enough for me. Far
brighter than the analog mode of my Echo Park, which is supposedly
modeled after a DMM)
C13 (will alter the way the repeats
degrade, keeping more treble in a tape-like way, cf build doc)
And
I definitely recommend a charge pump to run it at 18v. So much better
in both my builds!! (and that's the reason I use a IR9022 instead of
TL062 for the LFO, since 18v is the maximum voltage allowed for
TL062)

I'm starting to get very happy with how a pedal I've made looks. The enclosure is "silver hammer" 1590bb2 from Tayda. Acid etching enclosures and patching cock-ups with plates has led me think this one up. I just recycle old aluminum flashings, whatever looks like it will work. Most polishes up Ok. Some are a alloy and for that reason I started converting my hydrochloric acid to Ferric Chloride. It's relatively simple and I've found works well, and with other metal such as brass. It's all just hacksaw and file and plenty of patience. Drew it up on Inkscape and went from there. For now this is where I want to head on the look, which is becoming somehow a big part of the whole experience.
