Skreddy	Re: Designing a Tape Echo! Good sites to look up??? Analog Mike sells schematics for EchoPlexes (sorry, not browseable). I purchased them, and they include tube as well as solid state. As an aside, the tube input buffer in the old EP2 is a wonderful thing. I wish all of my effects had such a lovely tone and such forgiving headroom. I like the Echoplex design the best for guitar, because the tape-loop cartridge that it uses is not so smooth. Those little changes in resistance inside the cartridge result in a very subtle warble which creates a gorgeous, almost imperceptable, chorus effect when mixed with the dry signal. Plus Jim Dunlop continues to make them, keeping the price low. But for spacey stuff like infinite repeats that degrade into burbly noises with no random pitch modulation, the Roland Space Echo is king, with its free-flowing, loose, very long tape loop. http://google.com/search?q=EchoPlex+schematic http://google.com/search?q=Roland+Space+Echo+schematic
