I finished up a couple builds this weekend from my queue/backlog, one of which is the Pro-10 Blue. I bought this PCB somewhat on a whim, after feeling like "everyone" was saying it's one of the better-tuned Bluesbreaker-derived overdrives.

This build was more or less unremarkable: fairly low parts count, nothing fancy or exotic, smallish PCB. Had I built it in isolation, it would have been a fast build (but I've got just under 10 builds going in parallel).

No issues at first power-on, which is always immensely satisfying. And indeed, it sounds killer! Usually when I build a pedal, I do a quick power-on test, and if it works, I tell myself I'll come back later and really put it through the paces. But in this case, the tone immediately brought a smile to my face, and I spent some time with it straight away.

For the enclosure, I used the pricey Gorva Black Sparkle. I bought this over a year ago with the intent of using it on the one - that magic pedal that would make me forever content, and kill my desire to constantly build and test new pedals. I realized, I'll probably never really find such a unicorn of a pedal, and maybe I don't want to find it anyway, as building is half the fun. So in more practical terms, I realized that this Gorva Black Sparkle finish is too dark to take a waterslide decal (I don't have a color printer), and without a label, the pedal should have a simple interface. And what's more obvious than the classic three-knob volume/drive/tone controls? Furthermore, the Gorva 125B is just a bit smaller than a standard 125B, so a smaller PCB was in order. The Pro-10 checked both those boxes!

The bypass circuit is my own microcontroller-based relay bypass. (That was my other project this weekend, I built up eight of my v3.0 bypass boards, ready to rock for my next builds.)

Edit: keen-eyed viewers might notice that I'm running wires from my relay bypass board to the LED. This actually isn't necessary, as my boards support a PedalPCB "SW" connection, so the LED can be driven from the actual effect PCB, as typical for PedalPCB boards. I have dedicated LED wire holes on the relay board as a convenience (or when working with effect PCBs that don't have LED wiring holes, e.g. AionFX). So why did I make more work for myself? Brain fart, pure and simple! On one of my previous builds, I wanted to double-check the LED wire holes, and since then I've left my brain in auto-pilot, not realizing I was making more work for myself (and making the build messier).

Wow beautiful execution on all levels! Loving the added microcontroller relay bypass! The enclosures finish is incredible as well man awesome job.

I need to get around to building this, I too keep seeing nothing but high raise for this circuit.
