Seems like many of us chose a playing style first, and then chose a bass to suit it.
I had no particular style or heroes in mind when I went out to buy my first bass, and didn't realise for a long time how lucky I was that my beloved GMR 5 fell into my arms (almost literally), and how unusual her sound is. She has a very melodic sound, with exceptional sustain, and a perfect B string. I assumed all basses were like that, and had a shock when I first picked up a P-bass! My whole approach to playing, and to developing a bassline, is completely shaped by her sound and feel, although I do play other basses now and have become more versatile and punchy.
So I'm curious where other peeps are on this - did you start with a sound you wanted, or was there a bass that shaped or changed the way you play?
