The connection types are just simply two 1/4 inch jacks and the A/C power adapter input.
This is a floor pedal, so it isn't rackable. Nothing is worth kicking that high over unless you're a Rockette.
The general configuration is a simple as you can get. Just step on, and push down to suit your needs. And the set up is about as straightforward as you can possibly get. It even has labels by everything. It's idiot proof!
The effect editing is slightly irritating in that I don't remember if there is anything you can do. I may have done something years ago, but it is lost to me how of even what I did to it, even after taking apart the pedal.
The manual, from what I remember, was pretty clear. I did not use it much, and I don't know where it has run off to. There's really not much of a need for the manual, though, because the idea of the pedal is pretty straightforward.
The effect this produces is most certainly good and usable, though I'm not sure how realistic a wah pedal is supposed to sound.
I'll use this with just about any electric stringed instrument except for my acoustic/electric guitar, which would prove to be... Well... Not pleasant. I enjoy using it when my bass is plugged in for a bit of effect, and use it quite a bit while playing lead parts on the ol' six string.
I've been using this since the fall of 2001, and I have very few negatives to express about it. The thing I dislike the most is how sensitive the pedal is. It's very responsive, almost to a fault, and I've noticed this especially when there's a nice little pocket of tone at a certain point in the pedal range of motion, but it's very awkward to need to hold the pose needed from your leg to use that one solitary spot.
I am a Steve Vai fan through and through, and I felt that if this type of wah pedal was good enough to have him endorse the thing, then it would certainly be good enough for me.
in my opinion, the pedal is worth the money to get it used. It's a bit pricey, due to the sponsorship money they probably have to dole out to Mr. Vai, but it's a great pedal.
Knowing what i know now, though, I'm not sure if I would make the same choice in therms of wah pedals. The Classic Crybaby is a definite on the want list, but right now, I'm happy with my Bad Horsie.
