If you've never used a tape echo you've got to hear one to appreciate it. They have an incredibly wet sound that no other kind of delay effect creates. The fact that this one has an all tube signal path makes it even more unique and adds to the life-like, 3-D playback. These are pricey but you just arent going to find a pile of them laying around used, and given their high quality,high value construction cost is not really that high ( Tube powered stereo amplifiers are 3-5 times this much). Great for the intended electric guitar mission, but this could also be used in making techno music, or for sound processing for film or theatre projects etc., get these while they are still being made,. We all took this kind of stuff granted once and that was a lifetime ago, now.
