I had a good bit of noise from my strat, but I did a good shielding job on it and now it is as quiet as can be!
Your tech should be able to do this and it will greatly improve the tone, as well as the gain output of the guitar.
It will make the strat useable with any amp at any volume. It will sound big, fat and powerful.
Cheers!
YOu know what I actually put a new alder body to this strat wich has that copper shilding paint. I grounded it and voila! Yes sir is quiet as it should be. I wouldnt kknow how much the tone improved or if the new body just changed the tone a bit. It's now a bit more trebley.
