So I got the Octabvre Mini in and I got the Proton. Pretty sweet pedal day. I ended up putting the Proton after the Doom, because I love the downsweep after it. Super synth sound. Really takes it to another level. I do like this Proton filter since it can sweep up or down. I set it up so I really dont do much but flip that switch, and don't touch much past that.
The Mini Octabvre - damn. So I A/B'd it to my OC2 and it's very close. But, it puts out a lot more volume. So, I decided to use the Mini as my pure sub sound. It's just crazy good at that and I can use the OC2 for the more blended tone. I really like switching the tone knob to sometimes to the right. If you are running a synth chain, it does some nice subtle changes so you could use that tone on one tune, then flip the tone knob to the left or middle and the fuzz will react a little differently.
If I didn't use a blended oct2 tone as well, I would use the mini as my only octave pedal. It is that good.
