Hello KSD owners, I hope someone reads this that can assist me with a problem I have had with 2 KSD 5 string basses. I've owned both 5 string models and have had the same problem; a noise that sounds like a 'crackle' or static sound is produced when I lightly touch the strings. I believe the KSD come stock with single coils so I've shielded both PU cavities and the control cavity and ground all together - and yet the noise persists (even when the pan is centered). I would like other KSD owners to advise if they have had this problem and if so how did they resolve it. Thanks, my first inclination is to purchase humbucking replacements but I suspect the preamp and or electronics may be suspect. I will check the ground to the bridge connection too. I think structurally the bass is sound but electronically I have my doubts.
