oh man super close t the switch haha. have you considered using 9mm pots and 1/8 resistors?

Great layout and build! I especially approve of your stress relief on the wires. How have you grounded the enclosure?

hype? what hype?


great work so far!

Forgot about this, sorry. Will try to do that soon.


And, I meant buy an enclosure. I'd love to have a second one shaped like the Ernie Ball. I am unable to work metal with my current setup.

Any idea what kind of voltages are the transistors operating at?

Yes, I believe does 4 layer designs for some of his pedals. This is definitely one of them.

Another thing to note is that he has fairly small solder pads. This allows him to run traces between there, I'm sure.

I'll try to do that sometime this week. Any chance I could buy one, if you do?

Baxandall....maybe something like this?

I'm not having too much trouble, just approaching it linearly. I'm just not sure what the symbol at the collectors of the AC128 means haha.

I am trying to redraw it in Eagle, but I cannot understand the Ge side's symbols and such...

Why did you post your problem in this thread?
start your own thread dedicated to your build. This thread is even a different design than yours.


Additionally, the transistors are the problem. The Buzzaround requires specific gains and leakages. You should have bought a matched set for the pedal.

That's pretty good! Might just do the job...
Currently looking at this:

Nice and roomy, would let me build a couple knobs into it, as well.
so expensive though!

See the option with 5 stomp switches? Anyone know of a box that can fit two more switches? So like it's 40% longer than that? Haha.

^A transistor that is biased to be slightly gated can make a fuzz box pretty quiet.

I think shielded cable is good practice in higher gain circuits. Isolated the signals from each other is never bad.

i approve of your universally aligned electros.

I have a partially populated one, if you're interested.

So in the original OCD design, the cap coming from the opamp's feedback loop is going to ground. So this means that the signal loses half of the waveform, right? Could this be perceived as having lower gain? I ask because I built a design very close to this (called it the ODD :)) and my friend compa...

Nice! Did you create the pot library for those 9mms yourself?

WOW, so many transistors. And what are the inductors for?

I am hoping to see more light shone on this one.

How is the output volume on this pedal? Would it be wise to stick a volume put at the end?

I also jumpered the 100K resistors on the second opamp, seemed unnecessary since it's just a buffer.
