Hello I am an owner of a 2001 EBMM SR5, and its 4-5 months that I decided to upgrade it with the aformentioned pick-up and pre. Unfortunately, after several contacts with both John East’s and Nordstrand’s tech support (which they were very generous and helpful), me and my tech cant still find a proper way to make the installation work without ground noise !! At first, we swapped the original Musicman superswitch with a standard Tele 3-way (because Nordstrand’s support told us that their p-up wont work with the stock switch)... Then, we followed the instructions provided, installed correctly the pre-wired pre, shield the pickguard with foil, check every possible connection with the multi-meter, all showed good, but ground noise never dissapeared !!! Only when i touch the bridge... Also, if intouch the p-up with my fingers during playing, it makes some scratchy noises... any help???
