Purchased these to swap with the "speed knobs" that came on my 1991 Gibson Les Paul Standard.
Removing the original knobs was the hardest part, a little loop of fishing line made the job easier and safer than trying to pry against the body.
Take a piece of fishing line about 24" long and tie the ends together, slip the line under the knob ,(you want the Middle of the loop), and twist both ends in opposite direction a couple of times so that the knob is in the middle of the fishing line loop and pull up, the knob should pop up without risking marking the guitar body, your also not putting any pressure on the pot using this method.
These slip straight into place and require no adhesive, I'm not sure about the epiphone Les Paul's, I know they use different pots but these fit my 1991 Les Paul and I also tried them on my 2007 ES335 and my 2010 SG standard and they fit just fine.
They are a subtle change but they do change the appearance , they are not as easy to use as the speed knobs and can be a little slippery but are more of a traditional look.
