I've had quite a few products from Xotic (BB Preamp, EP Booster, SP Comp, Wah) and this is on par with those in terms of build quality and sound. The treadle is super smooth, very sturdy, with a very even taper, perfect for pedal steel swells and precise adjustments of volume. Even considering the "no potentiometer" spec of the Lehle Volume pedal (which is also a fantastic alternative, I tested it), I'd actually rank this one slightly above because of the build, feel and size of the Xotic.
Pros:
- feel
- taper uniformity
- size
- build quality
Cons:
- using a potentiometer (when compared to a Lehle)
