Based on that, if I had to make a single pedal recommendation: There is a pedal version of the Diezel VH4's third channel preamp, and PPCB sells a PCB of it as the "Valhalla Distortion" (AionFX has it too, as "DZ4 Preamp")
If you’re looking for the amp tone, I also suggest the Valhalla. The MIAB pedals just don’t quite cut it for TOOL tone in my opinion. Add in a Byzantium or mbp fraudhacker for the modulation sounds or you could even get away with a cepheid chorus. Delay tone is pretty straightforward. Just about any three knob delay with 500ms of delay time or better will do. Adam used a boss DD-3 pretty much his whole career but has been spotted with carbon copy deluxe lately as well if you want to get specific.
So I snagged a Valhalla board after reading this thread and just finished building it tonight. Holy moly do I love this circuit! I play mostly funk, blues, and jazz. Even though this is an extreme distortion circuit it sounds incredible and I'm super happy with it. Really appreciate the recommendation here a ton!
