I've done a few more than 3 but these came out best imo.

First is the Aion FX Ibex. This is a Roland AF-100 Bee Baa. The fuzz sounds pretty damn cool. It has a separate boost on a footswitch which, to me, does not make a whole lot of sense. Either way the fuzz is pretty cool. Plus there is a trimmer to fine tune the mids. Which is handy

Next is a PPCB General Tso. Which, if you are a frequent visitor of this forum, you know this is THE compressor. Not much more to say about it. I'm far from a compressor user but this will be an always on for my clean tone.

Lastly, a PPCB Sour Grape Fuzz. Which is a Keeley Rotten Apple Fuzz. It's a pretty cool opamp Muff. It makes good use of the TL074. I really like it even though it seems to remove a lot of low end. Which may or may not be a bad thing.

Satisfied with all these. I would have liked to paint the enclosures instead of them being bare (aside from the decal) but I don't have a good space to paint outside. Just enough to clear coat.

Anyway thanks for tuning in. Cheers to 2024.

Just built a Sour Grape and I found that most of the gain is on the last 10% of the Buzz pot.
When below, it almost sounds "overdrivey" which is not my experience with big muffs. I used a B100k pot as per schematic (measures 108k), and when in the middle it measures 53/55 so it should work properly. I read a build report by @xefned mentioning the same thing, is yours behaving the same way?

Yes, that's pretty much the exact same thing with mine too.

Thanks! It's strange because there's literally a spot where the gain goes BOOM
I wonder if a rev log potentiometer could work better...

I've looked around a bit and the general consensus seems to be that the trace reporting it as linear is wrong. Fuzzdog on his build documents for his version states: "as the trace has the fuzz pot as linear taper - no way. It needs to be reverse log to be any use at all, so that's what you'll get as we care."
So yeah I'll be subbing it as soon as i find one

So it should be C100k then? I'm going to have to try that for sure

I'm no expert but looking at the potentiometer "charts" a rev log gets up there sooner and has more control in the upper range so it should work

Makes sense. Only one way to find out for sure
