Yup! I was looking for a cheap fx box once and saw this used ART FX-1 at Guitar Center. I tested it there and bought it (think it was around $70). I only used it for a few days and then returned it, cuz I thought it didn't give me much control over effects. I since bought
the Alesis Nanoverb (also $70, but new, on sale at SamAsh) and realized that the Nanoverb has less effects and doesn't have much control over them, either.
I thought
the ART FX-1 sounded decent, warm reverbs, good chorus. Some neat effects, that aren't in the nanoverb. If it costs you less than $80, then it's a good deal, IMHO.
