My first bass was a blue Mosrite Ventures model. Got her in 1971, for $50. I was 16. She'd been sitting on the rack at the store so long that there was a worn spot on the back of the neck. She was so heavy, I used to wrap a bath towel around the strap to pad it. Her neck is so skinny, it's like a popsicle stick, short scale, with the strings close together like a guitar. I guess the Ventures' bassist had small hands. She worked for me, as I was switching from guitar anyway. Sound is twangy, great for surf music but not real versatile. She was my only bass until I got Old Faithful, a black and maple Precision, just before moving to LA in '78. For the next 13 years, Old Faithful was my main bass.
Today my main bass is a MIA Fender Jazz 5. I still play Old Faithful too, along with a Spector NS4 CRFM that I got last year. The Spector is tuned DGCF.
So I guess the influence my first bass had on me, other than getting me fully hooked on playing bass, was that she made me want a more versatile, conventional-sounding bass.
Here's Ms. Mosrite:
