I foot tweak my Heisey like crazy, way more than any other pedal on my board (ILFDD is a close second), so knob swapping the knobs had to happen for me. Here's the way mine's been looking for the last while. Kinda hard to see in the pic, but the giant volume knob is much taller than all the others, making it the easiest to grab in a hurry.
And btw: LOVE LOVE LOVE THIS PEDAL! Three insanely good sounding ODs all in one! I keep getting my mind blown by it!
I love this pedal so much. Last night I was jamming with this and my Beat Buddy and that's it. No desire even touch anything else. It's the perfect OD for my MTD. Works really, really well with actives!!!
