Not brilliant either, but not bad. Run from a PSU rather than battery, there is less 'tone suck', but suck tone it still does. Sensitive to location in the pedal chain. Before OD/Dist/Boost and it sounds a little flat, after, it can overpower in the treble range on all my amps.
To alter the 'range' of the sweep, merely alter where in the pot the sweep occurs. Simple instructions are readily available, but in short, jiggle the rack position on the pinion. Easy job and reversible.
Activation whilst standing is easy. Sitting down to play, less so. At least it can't easily be switched in and out, it does require some pressure.
Sturdy case/treadle construction. No worries about being heavy footed, it'll cope. Easy to modify.
For an occaisional wah user, this'll do. For someone who wants to wah a lot, there are many better options out there. Still, it is inexpensive and does the job quite well after the sweep range tweak.
Dropped a mark as it is now noisy. Servisol to the rescue, but the pot is already crackly to the point of annoyance as I'm use a fair bit of wah now.
