Hey guys. My USA Jazz Deluxe 5 with Noiseless Fender pups has had a pre-amp change, from the standard Fender one to a J-retro deluxe. However since the change everytime i touch the pickup pole peices there is a large amount of buzz. Touching the bridge does not make buzz occur however. Only when i touch the pickups. With the previous pre-amp it required the pickup ground to go to a grounding pin. With the J-Retro the pickups are supposed to be grounded to the J-retro itself it is currently wired like this. These diagrams explain better. http://support.fender.com/diagrams/basses/...5900_02BPg2.pdf - Original Fender pre-amp Schem http://www.east-uk.com/jretrodeluxe01.pdf - Page 5 for the J-retro Schem Any ideas?
