My first bass in my latter period of playing was a Fender Modern Player Jazz, in fact I had a Mk1 and a Mk2. Once set up they were sublime. I got both for £375 each. They don’t come up second hand that much,
I expect because it’s a shed load of bass for little coin. I swapped out the Mk2 neck for a fretless neck, it was lush. I think they were easily the best basses I’ve owned in a bang for buck sense, by miles.
