I bought a cheapy one off Amazon to try it out and it worked really well but had too high a noise floor, it got a bit worse when the board was in play. I've got a busy summer schedule and I am so tired of tripping over cables so I figured I'd invest in something a little nicer. Store I work p/t at has a bunch of the Boss Wireless stuff and the store owner swears by these pedal units.
I still have my Nady from the late 80's and it works great but is a bit too much these days lol
Got a gig Friday so it's right in the fire, I'll let you know
