Marcus Miller's fretless sustain
Has anybody noticed that when Miller plays a ballad he usually plays his fretless jazz bass (that is if he's not playing his bass clarinet). That instrument really sings, lots of sustain.
Is there anything special about his gear (other than the addition of lots of reverb, & brass bridge saddles) that facilitates that kind of sustain, that rough, nasal, guttural mwaaah?
I'm going to get a fretless Jazz bass soon, & I'm kinda shooting for that kind of sound. My bass will be a used Squire VM fretless Jazz, or a new (knock-off) SX 6 string fretless jazz bass, or a new fretless SX 4 string Jazz bass in a 30", 32", or 34" scale.
I'm afraid of having buyers remorse. In terms of getting the sound I want, is there any thing I should know about basses, effect pedals, electronics, playing technique, before deciding how much money to spend on this, that, or the other thing? I am on a budget!
