i installed a s.d. hot rails into the bridge position of my 2012 fender usa tele. using the wiring dia. on the s.d. site.put the guitar back together,hooked it up to my amp. & it's way to noisy [ i've used this p/u before with no problems] on a peavey reactor.do i have to change the vol.pot to 500k to calm down the noise issue ? i used the black wire as the hot to the switch as it states in the diagram.i thought i read somewhere that in this install,if your not going to change the neck p/u - use the green wire as the hot ??? thanks
