Picked up the Boss RE-20 Space Echo the other day, and i gotta say, so far it is sounding awesome through the C-Lator and Loop of my HRM Bluesmaster. No noticeable tone suckage from lack of a true bypass, and IMHO it is WAY better than the Tape Delay setting on the Line 6 box. Boss did a pretty good job of simulating the RE-201 if my memory serves me correctly (i got to play through one years ago when the local guitar shop had one laying around). It's a pretty fun and cool effect, although the built in reverb is a little wonky, but i just pipe it into my reverb pedal if i want reverb too. Just thought you guys would like to know that it is a cool option if you are into tape echo effects!
