So I'm not a real bass player (yes, the secret's out). I'm just a multi-horn player who always kind of liked the sound of the bass - perhaps because the lowest horn I have is only the tenor sax. Finally I got an amp and a cheap bass on Craigslist for under $70 last February, and I just went with it. The bass needed approximately two connections resoldered, and some pickguard screws, and some setup, but that was it. Bam.
This username was supposed to be the model of my trumpet (the Vincent Bach Stradivarius- the bass equivalent would be the Fender Precision for its widespread use) plus the first few serial numbers. As luck would have it, I remembered the model name correctly (yes!). However, I didn't look closely enough at the serial, which starts with 159, placing the trumpet at around 1978. So there we are.
I kind of like the ring of '151' better, though.
