Solid Volume Control

Ok, so I'm not really a player who tinkers a lot with volume. The styles of music I play tend to favor extreme tones, whether it's loud, saturated distortion/fuzz, or heavily layered time and modulation effects. I'm not someone who's going to "roll back the volume knob" to clean up a fuzz or an overdrive, because I just don't play the kind of music where that's particularly desirable. When I use this pedal it's basically for doing swells, or turning the volume down in a live setting between songs. The sweep is good enough for those purposes.

I will say that despite feeling like a brick, the teeth on the treadle got loose from the volume pot on mine, and I had to take it apart and reassemble it to get the full sweep back, so maybe the build quality could be better.

Smooth function, great taper, stays in place, never lets me down.

There are tons of volume pedals out there. I've seen some with marked volume levels, knobs, boosts ... All I really need in a volume pedal is off and on and the taper in-between for swells. This model never really goes completely silent, which is why I've given it 4 stars. But everything else is spot on. Quiet - no line noise - and does NOT color my signal. And yes, I've found other volume pedals that color the signal. Main reason I love this one. Does what it says and no extra surprises.

There are Better Options

Might be that it's just touchy, but I don't enjoy it much. If the pedal is at half, the guitar isn't heard at all through the amp. At full power, it's screaming. This is with the amp volume at 12 O'clock. Might need some work done, but I'm not impressed.
