I keep getting this slightly annoying 'click' when I play. It sounds like the strings are hitting the frets when I pluck. I raised the action a bit, and have made sure there's a nice bit of relief in the neck, but it still makes this click. I can cancel most of it out by cutting back the presence and treble on my sansamp, but I do lose a bit of high end definition. If it's any help, I never had any 'click' on the spector, and it has a much lower action than the warwick. Is it just a warwick thing?
