Well I just got my Spector back from the luthier today (got a new birdseye maple ramp installed) and when i plugged it in to play there was occasional crackling and popping, especially if I move the cable around. I opened up the cavity assuming it was a loose jack, it's not. and I know it's not the amp or bass because it did not do it on ym Aria or my Carvin (which actually has a loose jack) and I also tried different cables, they all do it. It's a Legend 6 with the side mounted recessed jack. (I was told they were pretty shyte as far as quality goes). So now I need to either fix it or replace it. What jacks could i replace it with? I've heard good things about neutrik but unsure if it will fit etc. Also could the problem be caused by something else?
