Just joined this group. Not quite sure how to read responses to my posts, so I'll post a question and see what happens. Question; I have a 1990 Gibson Lucille. Lately on various sites I've seen posts about converting Gibson stereo guitars to Mono. I don't really understand this question. On my Lucille there are two output jacks. If I plug into one of the jacks (can't remember this moment which one) it certainly seems to function fine as Mono. i.e.-both pickups working. If I plug only into the other jack then it only picks up one pickup. So why would anyone convert the guitar completely to Mono if you could just plug into the jack that can act as mono with both pickups working?
