I've used different ones in the past, a rackmount Digitech IPS33B, and a Boss Harmonist years ago. I've gone super simple with my setup now (tube amp and a [U]few[/U] pedals. I need a floor unit that can give me intelligent harmony without having to bend down and turn a knob for a different key. Doesn't have to be too fancy either...... Any thoughts would be greatly appreciated, I've been a bit out of the loop for this kinda thing for a few years.....
