For the audio engineering class (the second of two I took at OSU) the students had to do a recording project. Most (pretty much all of them) went out to clubs or bars to record a band playing, but my friend Steve and I had written the basics of "Time Machine" in the Fall of 1974, the two main guitar parts, and over the years he wrote the lyrics and I wrote additional guitar parts and the main bass line and, eventually, the synth parts on a friend's Electrcomp 500 that I borrowed for a while, so I decided to make the song my project.
We had a professional 16-track recording studio at our disposal for free

, so my friends and I and a few other students spent two days at the studio. First day was setup and tracking, the second day was a bit more recording (one synth part that I wrote but was too fast for me to play cleanly at tempo, and the piano which was a last second addition to the song [thanks, Isaac!]), then mixdown/mastering. Given more time (we didn't
really have a time machine around

) there are some minor things I would have done a bit differently regarding the mix, but I can't complain, we did a pretty good job for the short time we had available to us.
Yes, the AV '62 Jazz Bass had concentric controls; I removed the detented washers so the tone controls worked more smoothly. An old friend of mine probably still has her original stack-knob Jazz Bass (a white one IIRC, I haven't seen or played it since the mid '70s) that she got as a young teenager in the '60s.
There is a very interesting mix of Jazz and Rick tone to that Jazz Bass that I put the hi-gain in. Tremendous sound, actually, IMO. For the recording, the bass was run through my (at the time) amp, a '70s Furman green-face PQ-3 > Crown D150A > custom built (by my brother) cabinet with an Altec 421A driver, mic'ed with an AKG 414. My friend who has the bass (Isaac) also has that speaker cabinet these days.
The "Taurus" pedals is the Electrcomp 500; I played those and most of the other synth parts.
I got a A in that class.
