Hi all, Just wanted to ask for u guy's advice. I own a Yamaha BB605, retrofitted with a pair of dimarzio ultra jazz pickups. The problem with this bass is that there are dead spots in the C# to Eb range on the A string. These are not exactly dead spots, but you could obviously hear that the notes there sound thinner and have less sustain, especially when playing in lower temperatures.There are the usual dead spots on the G string too, but that doeasn't bother me as much. This is frustrating, as those notes on the A string are what most people, including myself, would play the most often. I've checked the neck, and it seems fine, with no signs of twisting or warping. I usually string them with D'addario or Ernie Ball's 130 - 45. Anybody out there with any advice? I thought of stringing them with lighter gauge(125 - 40) strings and putting more bow into the neck so that the problem will not be that obvious, but somehow feel that that will not solve the problem. I hadn't noticed this problem when I bought this bass 1 1/2 yrs ago,probably because I wasn't looking out for a fault like this. At home, where it is more warm and humid, the problem is not THAT obvious. I have considered selling this bass and getting another, but would like to hear your comments first. Thanks in advance.
