Oddly or not, I've settled into using my RE-20 mainly as a reverb unit. So simple, so old-school - Want reverb? Turn up the dial. Not a lot of finessing possible, just basic grunty reverb, but quite sweet sounding. I rarely use the RE-20 as "tape echo," mostly cos when I do, it reminds me it ain't the real thing, one of which I have back at my dad's. But yes, I'm quite fond of the sound and the lack of options regarding the RE-20 reverb.
