And then the G&L's are like a Music Man on steroids.It makes though because he started both companies.
As for the original post, I think it has to do with the fact that the body and the bidge have a nice bit of mass and unlugged, I'd say the setup really affects tone.
Agreed, it's the construction and setup. The woods used really have nothing to do with it, it being the 5 string version means it's got a heftier neck which will really affect the tone.
I played a fretless Sterling not too long ago (which I'd have bought if it had been an unlined version) and tho the rest of it was identical to the fretted model it had a completely different sound. The more mellow muted fretless sound and it only put out grit when I hit it hard. That was the 4 string, tho.
But both the sterling and stingrays just have that Leo Fender construction which gives them that grunt.
Agreed on the G&L (I have two). The fretted G&L's have even more grunt than the music man if you can believe it. Tho I think the G&L 4 string unplugged sounds a little more like a Fender P or J with a kind of acoustic-like quality. The 5 string has a flatter whack to it because it's built heavier and it does sound more "hi-fi" plugged in....
Still the music man is one of the all time greatest basses ever made....
