I went through a preamp phase last month and between this and the IVP Preamp build I think I am set (yea right)

Overall, this was an easy assembly, just a lot of parts. No traces to score for loop wiring, just a crowded PCB.

Swapped the called for 4558 opamps for Burr Browns because I am a cork sniffer, honestly I do not think there is much of a difference.

The only thing that I have not been able to do is set the drive and compressor trim correctly. I have no idea how to do this. My phone doesn’t even have a 3.5mm headphone jack anymore lol.

Channel 1 is a basic vol-treb -mids-bass EQ. You can coax clipping by just playing harder even at low volume levels.

Channel 2 seems to be more customizable, as I believe the EQ is a tilt style EQ. The frequency knob sets the frequency that the mid knob boosts or cuts, a very nice feature.

Compression is a bit non traditional but it’s nice to have. I set it to barely activate, but it can get some squish if set to full.

Overall, a very nice pedal, I love Aion’s stuff. I need to spend time getting the wiring cleaner, as I’m usually pretty impatient at that point of the build. I hate having wires draped all over (you should, and will see my IVP build). But it’s the fastest way to finish up…

I feel you on the wiring. I think Aion's wiring guidance also lends itself to longer, messier wires.

Damn!! I think I would be impatient too if I built that!

A relatively easy way to tidy up the wiring might be to disconnect them from the jacks, Feed them underneath the board between the pots and then reconnect them. You might need to remove everything from the enclosure to do it but I doubt it would take long. I suggest disconnecting them from the jacks rather than the PCB.

Another way to keep things neat is to route the wires around the edges of the enclosure using the corners of the box as a guide. I often do this and it usually comes out looking pretty neat. But in your case with this pedal I think using the PCB to hide them would work just as well.
