Firstly, it's built like a tank, I could probably shoot this thing and It would still work fine.
The sound is great, the knobs really do what they say. as in, you can get the full-fuzz sound at half the volume, or you can get barely broken-up sounds at full volume. The sounds are, of course, very Hendrixey.
Note: it does get quite noisy, especially with passive pickups. I now have an active pickup guitar and have managed to fix the noise.
The battery cavity is also very handy and well-built. Between that and the construction, it's a great pedal to take out on the road.
finally, the knobs and switches are well built, the LED is very bright and the knobs glow in the dark. I'm not sure if that's intentional, but they do. I love this pedal
