Inspired by @Dan M's build report of this pedal, I got stoked about building this board that I've been sitting on for quite a while.
Main reason it's taken this long to make to the top of the build list has been a couple of the rather uncommon components that has taken some time to find.
Mainly the CA3130EZ and the BA482 clippers.
I finally did find the opamps in the past couple of weeks (in two places of course) and now I have a few spares.
I dug through the old threads where @Chuck D. Bones talked about substitute diodes and decided to go through my meager stash to find a suitable substitute
and the closest thing I found was the MA858's (in terms of Vf). So that's what's in there now. I may play around with some of the other alternatives, like using half of the diode pair in a JFET or BJT transistor
But it sounds pretty darn good as is, I might just leave it!
Really cool distortion pedal, it's got more gain than I generally know what to do with but it's thick and chewy all the way through the range.
I'm liking it with the gain around 9 o'clock and boosting it with the Closed Circuit Booster Limiter I just finished.
Checking it out with my P90 Tele it's pretty kicking. Big and wooly on the neck pickup, snarly and spitty on the bridge.
The internal boost is also very functional and usable (as opposed to some other distortions with a built in boost...cough,cough,JHS, cough)
The only other substitution I made was 1n4001's instead of the 4004's. From what I can find from the data sheets these have the same Vf range and since they are employed with the 4148's as clipping pairs I don't think it will make a lot of tonal difference.
Thanks @Dan M for pushing off the fence on getting this built! Nice add to the collection.
Using Tayda's Matte Violet. It's much more subdued in person than in the picture, cool color!
I pushed the footswitches out a bit for a bit more room.

(Not recommended strategy btw)
