That's true for me as well.
I'm amazed my parents put up with that band for so long. They were mystified about what I and the other guys were doing down in the basement making these weird noises in between the surf tunes, Hendrix, Yardbirds, Airplane... My Dad had a clue because he was a 50's jazz fan...
Back then I played an early 60's Gibson Melody Maker customized to within an inch of its life, later a '63 SG which I still pull out at times, though most of my performing and recording these days is on a triple-pickup Black Beauty Les Paul Custom.
I play keys and bass in addition to guitar, so after high school (where I played mainly guitar) I had the opportunity to rediscover a number of these tunes playing keys (mainly Fender Rhodes piano and early monophonic synths) in a jazz lounge band. We snuck in Zappa material whenever we could get a chance, typically towards the end of the evening when the management had faded out. :-)
Very good reading you man. Cheers!
Long live Zappa
