I've had similar ideas with the DS-1 and the SD-1 on guitar. There's a part of me that wants to create a no nonsense old-school Swedish Death Metal board for guitar, and I know all sorts of bands used those in various configurations and permutations with the HM-2, either boosting this with that, or some such stuff. I think also the MT-2 was used occasionally? Seeing as I've already got the HM-2 part covered...
In other news, I've been trying to up my guitar game, and think I'm doing pretty well. Definitely getting comfier again. Unfortunately, one of my guitar rigs has now developed a "pop" when I engage the pedals in the FX loop. I've solved it for the moment by swapping two near identical pedals between the two rigs (the DOD FX10 BiFET Boost and the more recent Reissue), but I know that's likely not a long term solution. It seems to be a buffer issue as far as I can tell, so the modern one will likely work better as the buffer on that is controlled via an on/off toggle. Anybody know what would randomly cause the pop to just appear? The only difference between now and previously is the addition of a mini tuner, which is true bypass, and that was added a few days ago. So while it's new, the problem didn't appear until after a few days' use.
