Okay so everytime I am at band practice my Jazz pup on my Ibanez Sr400(active) is cutting out! It only happens after I have been playing for a while and if I put it down for like thirty minutes it starts playing again. Now the P bass Pup by the neck works fine all the time. Now my question is that I figure that I am going to need a new Pup to replace the J bass one, but I am not sure if something else would be causing the problem. I mean I even took it in to the shop where I bought it and they obviously said nothing was wrong cause they couldn't get it to duplicate the problem cause it only happens after it has been playing for a while. (And by the way it is not the battery cause I have already changed it.) Okay the question here is if it is the Pup should I get a set for both to match or just the J bass one and what brand would you recommend for a nice Dark metal tone. Lots of Dropped C songs... And if it is something else where should I start looking. Thanks in advance!
