To be honest, i didnt notice any difference in the neck position, but then again, i barely ever used to play the neck pickup.
The bridge used to sound thin and generally pretty bad, so to remedy this i used to turn the tone down and used the bridge/mid pos. while this still didnt sound great, the lack of highs made it sound a bit fatter, and i didint have to put up with as much noise (i live out in the country, so eletric fences etc. have a big impact). However, since changing them, i found the bridge to be much better sounding cause of the increased bottom end, even with the tone up and the bridge only selected. So now im willing to put up with the annoying interference and 50's cycle hum (casue its 50Hz AC power here, not 60) simply casue it sounds so much better now. unfortunately its still a bit thin at the really higher frequencies like during solos.
considering its difficulty (or lack of) , i think it is an amazing mod for the squier, it gave me enough extra out of it to keep me tolerant for another 6th months (Scheter C-1 Classic comin soon :D )
