Everything I wanted
First of all, Sweetwater's service was excellent as usual.
I got interested in this when I heard rave reviews of the VT Bass, but figured I didn't need another overdrive pedal. With 6 presets, effects loop and DI, this became a must-have. It does everything you think it does, and I've dialed in 6 really usable tones, from light, transparent overdrive, scooped metal, tone-destroying fuzz, etc. Also, any preset "remembers" whether the effects loop was on the last time you used it. This cuts down on tap-dancing for live use, since you can just set it up so when you switch to a new setting, you automatically get your phaser/filter/whatever. Also, when you're messing with a saved preset, the light flashes to tell you how far you've turned a knob away from where it's saved. This is a huge help for experimenting. THe knobs are very reactive, and a little drive goes a long way.
All in all, I'm so glad I bought this, and it's replaced 3 pedals on my board, and re-organized it nicely.
