Here's a decent demo of what the pedal can do ...
And it is a nice demo, but I'd still be really interested to get your or anyone else's impressions of the pedal, once you get your preferred amp sorted out.
I kinda like fuzz and octave effects better than overdrives, because the decay of a good fuzz is just so interesting, the way different parts seem to fall off at their own, independent rate, and the notes sort of come apart, rather than fade off ... so beautiful and weird ... and you can get a strange exaggeration of the harmonics of a nice, harmonically rich instrument - or even a total transformation! To my ear, they tend to push the centre-heavy sound of a Strat into the territory (I suppose I mean in terms of the double-tones and harmonic richness) of an old Les Paul, but with a crazy, dark, almost comic-book-like twist.
And with a Les Paul, they do very interesting things in response to the volume and tone controls. I find my fuzz pedals are a bit unpredictable on the neck pickup in the way they respond to a tone roll-off; the highs don't come off, but they do change; hard to describe, but they sort of shift from "clarinet" over to "flute". I love it!
And - with an octaver - I find I can kind of bring the octave in and out of the sound, without too much drop in volume, by playing with the upper third of the volume controls, especially on the neck pickup.
Did that demo go into the response of this particular pedal to the guitar's controls? I didn't make the time to watch all of it ... and it'd be more fun to hear from some users here on that point anyway.
