My first keyboard was a VL-tone and when I "borrowed" the 3M Wollensak reel to reel from my high school, I started cutting up tapes. I had no Idea what I was doing as I was 13 at the time but it was quite a lot of fun anyway.
Two of my other friends that same year bought a theremin kit and I got to use it after they got it together. For drums, we could always count on the decrepit CONN theaterette 355 organ with it's destroyed Eprom to bark a furious keith moon deluge of percussion. I got in there with a screwdriver and tuned the whole rig an octave low for extra bass.
it was all leftovers from the sixties that we had to play with. We were quite happy when we found a non-suitcase rhodes in one of the bandroom closets.
Pity we never recorded anything- The leslie unit on the organ began to catch fire.
