NickH Posted December 2, 2009 Share Posted December 2, 2009 Here's a circuit I drew up for Muzz for his JAzz, which is to be fitted with Seymour Duncan Vintage single coil pickups. Normally the pickups are in parallel when both volume pots are fully up. This switch puts them in series instead, which gives a much fatter, edgier, louder sound. Tim Commerford from RATM / Audioslave wires his Jazzes like this all the time (I'm reliably told). Give it a go and have fun! Excellent way to get more tones from a twin sc/pup bass. (This will work with humbucking pickups too naturally) PM me for any wiring help / technical advice Nick Quote Link to comment Share on other sites More sharing options...
guybrush threepwood Posted December 2, 2009 Share Posted December 2, 2009 Did this mod on a jazz bass a couple of weeks ago, quite quick and easy, and sounds fantastic Quote Link to comment Share on other sites More sharing options...
The Bass Doc Posted December 2, 2009 Share Posted December 2, 2009 First did this about 1990 - beat Fender to the S1 idea. Quote Link to comment Share on other sites More sharing options...
lemmywinks Posted December 3, 2009 Share Posted December 3, 2009 Cheers! I'll be getting this done to my fretless Jazz in the new year. With series/parallel switching and a piezo bridge it's gonna be ace! Quote Link to comment Share on other sites More sharing options...

With a three-position mini toggle or (my preferred option) a rotary switch you can series / single / parallel each pup as well as have series / parallel between the two pups. (I figure any man who's gonna put a piezo in it will not be adverse to a bit of technical chicanery under the bonnet of the bass ) Going to install a seperate jack for the piezo output, or run an onboard pre and blend it in, or break it out with a stereo jack and lead into a belt box?

Al Heeley Posted December 5, 2009 Share Posted December 5, 2009 I fitted my zebrawood thru-neck bass (JB pup config) with this option on a mini switch but it sounds so much better I never use the original option now. Quote Link to comment Share on other sites More sharing options...
