Funny, this deck, and the DIY analogue manipulation stuff I see floating around connected to synthesis reminds me of a weird device I built in college, built around one of thsoe decks which I’d dissassembled. I built a hand-cranked cassette drive, with the tape passing over the playback head, wired in to an amp, and a bunch of other stuff I can’t remember clearly. The visible aspect of the device was as much a part of it as its sound, using brass sheets, tubing, plexiglass sheet, etc. It got used in a few performances, alongside loops spliced together from recordings on some ancient modular in a lab I had access to.
I also took the circuit board out of one of those decks and soldered random leads to various places and connected it all in to the in/out chassis of a home-made guitar effect pedal…and ran whatever audio I pleased through it. Truly random results, with a couple pots hooked in. Probably lucky I didn’t electrocute myself in the process. An oscilliscope saw occasional use too…somehow.
College.
