Everyone loves an echo... an echo ... an echo, right? I'm jonesing hard for an old tape echo machine (used to have a whole variety of Space Echoes back in the states, RE-101, RE-150, RE-201, etc.) for live and recording use here in Europe, but prices on the older Rolands are through the roof right now (1500+ for an RE-101). So it's time to look at other options. I figured I'd take a look at some of the other tape echo brands like Klemt, Echolette, Dynacord, WEM/Watkins, etc. I'm mostly interested right now in the older tube models like the Klemt NG51, Dynacord Super S62/S65, or the Watkins Copikat mk. II, but I'm not opposed to solid-state models, if they've got good, interesting pre-amps like the Space Echos or Echoplexes. I'm even tentatively looking at oddball stuff like the old Czechoslovak Tesla tape echoes (because I speak Czech) and older Soviet/East Bloc tape echoes too. Mainly I'd like to have one to serve as a preamp for recording/adding grit to guitar sounds, self-oscillation mayhem, and for use on vocals for home recording. I'm not really worried about live use yet. So, anyone have any favorites or tips? How does the build quality and maintenance on some of these older German models compare to the Echoplexes and Space Echoes?
