nozzles Posted March 7, 2021 Share Posted March 7, 2021 Hi, my first Gibson, a 98 Lucille ... does anyone know why sometimes I plug into the top jack and it gives me both pickups and other times, only one? Just trying to determine if the wiring is messed up. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
jdgm Posted March 7, 2021 Share Posted March 7, 2021 The guitar is wired for stereo output from one socket, and mono from the other AFAIK. Probably you are putting a mono jack into the stereo output....? Quote Link to comment Share on other sites More sharing options...
nozzles Posted March 7, 2021 Author Share Posted March 7, 2021 It seems to work, by allowing both pickups, if I use the jack closest to the strap pin. But the problem is that it doesn't work consistently (definitely only get the bridge pickup with the other jack). This is why I'm suspecting that something needs cleaning? (I prefer to leave the original wiring intact). Thanks for the response! Quote Link to comment Share on other sites More sharing options...
jdgm Posted March 7, 2021 Share Posted March 7, 2021 (edited) It sounds to me as if it is all working as it should; for the top jack input (I think) you need a stereo Y-type cord which has a 2-ring stereo jackplug the guitar end, and a mono on each of the other ends, then....2 amps. Would sound brilliant but a bit of a hassle. You might find that by pulling your mono jack plug out slightly it engages the other pickup instead. (EDIT) Here is a thread on it from 2017 started by Steve Ford. This is why I think the top jack is stereo.

Sgt. Pepper Posted March 7, 2021 Share Posted March 7, 2021 (edited) I owned one. One jack, I believe the top works like any normal guitar with one jack. When mono cables (mono not stereo) are plugged into both jacks it splits the signal and one cable is the neck (I think the top) and one is the bridge. And you can sent the signals to different amps. I only did it a few times. Cool feature but 99.99% of the time it was never used like the Varitone, I rarely used it. Edited March 7, 2021 by Sgt.

kaicho8888 Posted March 14, 2021 Share Posted March 14, 2021 Yeah... the input jack closest to the strap pin is for mono. The other is a stereo jack and you need a TRS plug for stereo output one for each pickup. Like you mentioned, could need a good jack cleaning... spray deoxit or just roll up a fine sandpaper and use it like a jack. Might as well clean the toggle switch and pots too!

Sgt. Pepper Posted March 16, 2021 Share Posted March 16, 2021 At least Lucille has a control cavity cover in case you need to change something out. Quote Link to comment Share on other sites More sharing options...
