Guest icantbuyafender Posted March 8, 2009 Share Posted March 8, 2009 Uhm i used seymour duncans wiring diagrams to setup a coil tap on my single humbucker junior. thing is, i get a nasty feedback and noise wall everything is in place... ground wire issues or what? ughhhhh http://www.seymourduncan.com/support/wiring-diagrams/schematics.php?schematic=1hum_1vol_1tone_split i just want to cut out that damn feed back wall. would unmatching output pots (a 250k, and a 500k) be a reason for the feedback?

Steven Lister Posted March 8, 2009 Share Posted March 8, 2009 Re-check your wiring using the accurate diagram(s) found at this link ---> guitar wiring diagrams I have found diagram errors on multiple web sites, including Seymours, so that may be your problem. If your wiring is okay, then make sure your pup/pots are all grounded together. Mis-matched pot ohm values do not create noise in my experience. btw - I have a GFS vintage '59 split and it has great tone & low noise in single mode. What pup are you using? Hit every BLUE NOTE baaaby..., I'm going to play on:-" Link to comment Share on other sites More sharing options...
lpfan Posted March 8, 2009 Share Posted March 8, 2009 Definately check your grounds. Thats where I would start. Good luck! Link to comment Share on other sites More sharing options...
Guest icantbuyafender Posted March 9, 2009 Share Posted March 9, 2009 yeah guys it was a ground issue! of all things the input jack crapped out. so, a handy spare switchcraft jack came to the rescue. a 5 minute (less really) swap of inputs really made me a firm advocate for switchcraft products. a beautiful silence with only my reverb and strings being heard. now that was an experience. i rewired the damn pots so many different times trying to see what was up, and it turns out to be the most obvious thing (due to the annoying feedback that screams bad ground connection) thank you steven and lpfan.. hah stress over a bum input jack Link to comment Share on other sites More sharing options...
lpfan Posted March 9, 2009 Share Posted March 9, 2009 Glad you got it fixed. Enjoy! Link to comment Share on other sites More sharing options...
Guest icantbuyafender Posted March 9, 2009 Share Posted March 9, 2009 yeah!! a coil tap really gives that single coil fender-ish vibe when you use a TBX tone pot. then just push down and boom! High output pickup humbucker! this LP jr is no longer the "one trick pony" i thought it was Link to comment Share on other sites More sharing options...
Dave Posted March 10, 2009 Share Posted March 10, 2009 I need to do that on my flametop. Have you ever seen the switch arrangment on Brian May's homemade axe? Must be 9 slide switches on that guitar. Link to comment Share on other sites More sharing options...
xdouglasjordanx Posted March 10, 2009 Share Posted March 10, 2009 do you find that it starts and stops as you touch your knobs? becasue if so just check your bridge ground and make sure it is in place and what not, in wiering you may have pulled it out abit.. or forgot it.. some active p/u have output grounds.
