Solidly built, knobs feels good, soft-touch switch is nice, all metal enclosure at this price is great. Typical TC quality, it's a tank.
I was looking for a cheap fuzz, and a lot of places online call this a Big Muff-style pedal - it's not. It never gets that creamy, violin thing going on, it's always a buzzy, vintage fuzz. The tone control is kinda Muff-ey (it's doing a lot of stuff, not just rolling off top-end), but with a bigger range - I think it'll probably work pretty nicely on bass.
Can't argue with that price though, probably going to check out some other stuff in this line.
