There's no shortage of positive feedback around here for the Mercurial Boost - add me to the list of endorsers! I built this with the intent of generally using it as a lead boost. I've been using my Prismatic EQ for that role (and it works great for that). But I thought the Mercurial/Vario looked really interesting, so here we are! (Next on my list is to make a clone of the Boss PQ-4, similar to the Ravager.)
The build was super simple. It's a small board, with a fairly small number of parts. The only possibly non-typical part is the dual-gang A100k pot. It calls for two TL072 opamps, but I found I'm actually out of those! So I used an expensive OPA2134 for the IC1 and NE5532 for IC2. Works great!
The enclosure is a 125B Pro in "Tango Green" from @StompBoxParts. I love this color (check out my Andromeda Deluxe that also used this box).
The only thing that might need to be addressed is that my relay bypass board is just "floating" in the case, held in place only by the four wires that connect it to the effect PCB. Usually the effect PCB is bigger, and I use double-sided foam tape to attach the relay board to the stomp switch.
Edit: The eagle-eyed among you might notice a mistake: the input/output triangles are facing the wrong way. Sadly, it's not the first time I've done this!
