Semi-Sweet Distortin low output and high squeel

[taylorbusby]

I just built this today and it sounds great but I can barely get it to unity. I have to keep the level dimed. I also had a high squeel going on which I fixed by changing one of the 220pf to a 1nf. Ive double checked all of the components and everything seems to be where it needs to be. Wondering if anyone else has had these problems

Check r14. It should be 10k.

If I have the right schematic, you could lower that to something like a 3.3k but you'd need to change the 1nf to compensate for the extra high end. I'm guessing something around a 3nf would keep things more or less copacetic.

And there's no 220pfs ok the circuit btw, only 220nfs.

In the circuit I used there is 220pfs (schematic attached). R14 is showing to be a 15k. Would changing that tame the squeel?

No 220pf cap on there.

That’s the SS-2 I did the SS-3
