Just wondering what you guys would recommend for a relatively inexpensive multi-effects pedal for small gigs. It would be used mainly for rock, but I would like it to have a decent wah pedal. Thanks.

I use a ZOOM 504 II.

I keep it on the D5 setting alot. I got mine used for like $20. They don't make them anymore so it maybe hard to come by.
Here I am using it live.
