I'm basically looking for a Rack Unit that has chorus, reverb and a Tuner. I play acoustic. I don't want my sound to be tainted when its in bypass mode. My budget is probably around $300, maybe less. The TC electronics g major had caught my eye, but I have read in reviews it can color your sound when bypassed. Also I don't need/want all those effects.

Thanks for your suggestions
Most MultFXs ur gonna find will probably have way more than you need. Especially rack ones. With a budget of 300$ it's very hard(if not impossible) to find a rack unit that's worth the money, and suits your need. You're better off buying single pedals.
