I may be a slightly out of my depth here, but looking at the schematic, the sweep switch has 9v coming in on the "A" pins, so if you can figure out what resistors work best for the up/down modes you might be able to tap the voltage from the existing sweep switch at pins 1 and 2.

Maybe, up/down mode changes might require you to tinker with the cutoff point. I still want to play with this a bit more. From my limited testing this change may actually be a negative for guitars with really hot pickups. There's more variation across the sweep but the actually usable area feels...

Nice, I just tried this out real quick as well and I think it certainly helps bring more range. I grabbed ~9v from pin8 of the same chip. I think if you carefully bend the pins of the trim pot you might just be able to tack it to top of the chip with some hot glue and solder the trimmer...

I now realize that I think your problem is with a different pedal and that you just popped into this thread since it seemed similar. You can always try the output as well, but in my case with the Tyrian it was unnecessary. Other people have built the Tyrian and not had the same issue so 🤷‍♂️.

My Tyrian whistled like crazy until I used shielded wire for the input jack.

One side should be grounded. Be careful that on the non-grounded side you don't have any tiny pieces of braid exposed that could short on something else.

It is, without the shielded cable it screeched and whistled like crazy. I didn't have any shielded cable on hand at the time so I just hacked up a cheap pedal patch chord for instant gratification. Since then I've purchased...

I haven't played with the loop too much. The docs talk about putting your input signal into the loop return and then adding something like a drum loop, vocals, etc to the triggering input for all sorts of fun and games. I haven't tried any of that stuff yet. The downside to the loop is things...

I bought then from smallbear before they sold. At the time they listed the MCD value, but now I don't see it. I think the ones from Mouser linked from the AionFX BOM are also lower MCD. The settings can be picky. Check out the original manual for some insight...

I'll squeeze in one morereport before the end of the year. There are quite a few build reports on this one with different opinions. The actual build itself I wasn't super excited with. To start with the build docs have the wrong dimensions for the top jacks and the expression jack. The...

Funny enough I did something similar with OpenSCAD to verify my drill coordinates for Tayda. But I didn't print the actual enclosure I just did the faces and then I export as PDF and print them and compare to the build docs to make sure things line up. Printing is obviously better, especially...

I cut the pins down a bit to compensate for the added height from the socket. It'll fit.

I consider your praise a high honor :) Thanks

I also found people reporting the same behavior on the pedal directly from EQD. Here are the threads I previously posted in about it. https://forum.pedalpcb.com/threads/ticking-from-superheterodyne-receiver.11755/...

Mine too, it makes me angry. I never figured out a way to make it stop. I posted in a few other threads about it. Sagging voltage from a battery made it go away, but I couldn't reproduce that behavior messing with dropping the input voltage with diodes.

I'm not much of a bass player (I'm not much of a guitar player either for that matter), but I have a bass player friend who was interested in pedals and I needed an excuse to order something from Madbean. I spent far more hours on the artwork for these than I'd care to admit, but I think they...

I was just trying to put together these drill plans for myself and it looks like the AionFX docs are actually wrong for both of these. The layout on paper is fine (though a snug fit), but the dimension numbers are incorrect. You can see this visually if you look closely and compare the outer...

I've used 2SK30A-R in place of J201 in some pedals. They can have similar Vp/Idss values.

Ouch! At the end of the day I only needed to desolder 16 or so resistors, so not the end of the world, but that moment of realization stung. The board cleaned up great and looks brand new. It most certainly could have been worse.

Oh man, that's one of those moments that I'm sure you felt like you were watching in slow motion. I hope you found everything.
