Recently had a coolrail installed in the bridge of my strat and the tone wired for the bridge as well. My problem/question is in the fourh postion on my pickup switch (the one for middle n bridge both) seems much noticably quieter
Fender strat
Frontman 15r
Crybaby wah
Jamman solo

Martin sigma
Lace acoustic pickup
The Coolrail is out of phase. There are 4 wires and shielding on that pickups, the two wires that are soldered together are the wrong ones for this application. You will need to look at SeymourDuncans's website for which wires to solder together to be used with Fender pickups... Ie. If Red and White are soldered together, it should now be Black and White... and Red would go to the switch.

If you had someone do it for you, have them swap the wires, shouldn't take long at all.
