I grabbed a Multivox MX-312 Multi Echo off Craigslist recently and finally hooked it up to #857. Holy shit! Nothing compares to tape echo and spring reverb. The 312 is an off brand knockoff of the Roland RE-201 Space Echo with some additional features. Particularly "swell reverb" which adds a swelling echo to the reverb signal. Lush doesn't begin to describe it. My advice: If you haven't tried your tron thru an old tape echo/spring reverb, you haven't lived. Tape to tape is a beautiful sound.
Now back to playing some Starless...
