I've had a SubT for just over a month now, and it's proven to be quite a versatile pedal. I mentioned in my first post about it - which was after only a few minutes with it - that I wasn't blown way until I combined it with other pedals. But that's really because I'm quite good at make great pedals sound average, and also because I feel like the real magic in most pedals is found when using them with other pedals. So that's not to say that the SubT doesn't sound good on its own. It certainly does. It didn't take but a second session with it to get a great, more traditional, octave sound that sent my MXR BOD packing. (For the record, I've had a BOD for years and although I was aware that better octaves were probably to be had, I was always very happy with it. What can you do?) Also, you can get a sweet dub tone out of the SubT by rolling off the "Clean" and finding the sweet spot on the "Filter" (both synth knobs rolled off too). I'm sure that I'm not telling all of you SubT users anything that you already don't know. [Invalid or Expired Link Removed]
But what absolutely floored me was its ability to make negative sweeps on filters sound so good, because I've never been able to achieve it at this level. It's ridiculous. The only thing that I've used that gets close is an EHX BMS, and that pedal does negative sweeps really well. But the SubT, along with my Proton or BEF Pro, had a fuller and more present sound to it - one that has worked better for me in a mix. The Octo and Uni Synth work great for this too (Octo Synth around 8:00 and the Uni Synth around 11:00).
The only pedals that I keep in front of it are a ss/bs TAFM and a 3Leaf You're Doom. I've always kept the TAFM in front of my octave so I can better control how the gate opens, and I just started recently putting the You're Doom in front too. It sounds great both ways, but with it in front, I can better control how the pedal responds to dynamics, and the You're Doom is exceptionally responsive to dynamics.
Yup, very happy with my SubT!
