I've never really been impressed with the demos I've seen of the Subterrenean. It also had that low-fi, almost 8-bit, sound and was kinda messy. Much prefer the fatter, cleaner sound of the FI. I just wish the FI tracked sounds without any kind of envelope in them better. The sounds with an envelope dialed in the filter track great! Take that envelope out and it becomes temperamental.I think the Subterranean by Iron Ether would be a good start too.
It’s not a thick sounding fuzz on its own but definitely does the sawtooth thing well
I've got a Meris Enzo on the way (despite it being a pitch tracking synth pedal and not a dedicated fuzz), since I know and have heard it do what I want, and despite the mixed reviews on here in regards to the tracking, the fact that it clearly labels how to turn the envelope off on the pedal itself gives me hope that the tracking was designed with that type of sound in mind. If not, and it doesn't track any better or worse, then I made sure to get it from somewhere with a good refund policy and will send it back.
I still would like if a dedicated fuzz pedal could get close, since it already sounds so similar to a fuzz. The Doom 2 certainly is close. If it had a little more bite/more of that choppy buzzsaw like sound, I probably would have already bought one. Maybe need to look for something like a gated octave-up fuzz. Sort of like a cross between a Mastotron and Doom 2, where it still has those higher pitched harmonics but with a pinch knob to make it tighter.
