Greetings, all. I picked up a Squier VM '77 Jazz here recently, and it's just fine for the most part, but I eventually began to notice that notes on the G string have a sort-of "chorusy" sound to them near the nut and progressively get more "tremolo-y" as I go higher on the neck, such that by the 12th fret, it sounds as though I'm running through a tremolo pedal with the speed set pretty high. FTR - I'm tuned in "D-standard" (whole neck down-tuned a full step) and the bass is intonated for this tuning. I don't notice this issue with any other string. Any ideas what the problem could be? Thanks for your time and assistance.
