Disclaimer: This may be already be pretty much common knowledge to everyone else here but me, but thought I'd pass it on in the hopes that it might be of help to some other bass newb like myself who might be both lurking here and considering the purchase of a Mustang. Background/context: I bought myself a Mustang Bass RI (MIJ) about 6 months ago. Being a longtime guitar player but new to bass, I picked short scale thinking it would make for an easier transition from guitar than a 34"-er. I also have arthritic thumbs and have found that short scale is easier on my old hands. My Mustang came from Fender strung with their (.040"-.095") round wounds. Right out of the gate, I wasn't happy with the sound or feel of the E string: felt too rubbery, sounded unfocused, almost distorted relative to the other strings. Posted here on TB, asking how I might remedy this deficiency and was advised that higher tension flats would help. Got distracted by another bass for awhile but recently returned to the Mustang and restrung it with D'Addario Chrome (.045"-.100") flats and set it up, which felt and sounded a lot better. But I still didn't like the sound of the E string. This evening, I started fooling around with the pup height adjustment and BINGO: was able to achieve a much more satisfactory sound out of the E by gradually lowering the end of the pup under it. Feel like an idiot for not trying the pup adjustment sooner: I just got too focused on the looser, short scale, string tension and assumed that that was the only issue in play. Live and learn. Certainly supports the old truism that you should never assume that your instrument comes dialed in to perfection from the factory. To be fair to Fender, I need to say that my Mustang is flawless in terms of fit and finish: it just needed a string change and some adjustment to allow it to live up the its full potential.
