Re: Jimi Hendrix JH-1 crybaby
I had a pair of JH-1's, they're good, nice fat sweep. However note that the effective range of the sweep is mostly in the midranges. This means that you won't hear much if your tone is scooped out, whereas if you have a stratty or mid-heavy sound you'd probably be pretty impressed.
So your friend may have to use a different guitar tone to fully take advantage of it, depending on what he normally plays leads with. Most wah pedals have a set range they work with, except the ones where you can program in the sweep range, like the dunlop rackmount.
Having said that, it's a great pedal and very effective.
