I have a Classic (Premium Plus) that I thought was a dud for a long time tonewise, but I think I finally solved the real issue!
I'm not a die hard a Les Paul guy, my only one is this one. Was struggling to like it after multiple pickup and pot swaps. I finally got looking into the bridge, based on reading about upgrades like Faber.
The Classic has a vintage type ABR-1 bridge, not the typical Nashville modern Gibson bridge with metal body inserts.
This is what the ABR-1 looks like out of the guitar:
If you take the strings, bridge and thumbwheels off, you are left with those two skinny little threaded rods sticking up out of your guitar top. They thread directly into the wood. On my Paul they were loose and wiggly, you could easily wiggle them side to side in the hole with your fingers. So I removed them and used a toothpick to roughly measure the hole depth. My holes went down almost 1/2" deeper into the guitar than these were set to. Just didn't seem right, how could the guitar resonate with loose posts?
Shouldn't those posts bottom out tightly right into the wood?
Of course they should! But Gibson drills the holes too deep on purpose to make assembly fast and easy, that way they can quickly thread the posts only as deep as they need to go so that when the thumbwheel and bridge go on top the post height lines up nicely with the top of the bridge.
The fix was easy.
1. Bought some long stainless steel bolts with the same size threads, but twice as long, with Philips heads.
2. Used a Philips screwdriver to drive them into the guitar down tight. Not so tight that the threads strip, but tight enough that they sink a bit right into the bottom of the post hole and the post ends up solid with no wiggle.
3. Used a Dremel to cut the Philips heads right off at the top.
4. Put the thumbwheels and the bridge on at the correct height so you can see where to mark a spot to cut the posts down again to line up with the top of the bridge nicely.
5. Remove the bridge, Dremel the posts off again, at their ideal final height.
6. Use a different Dremel bit (or files or sandpaper) to polish the top of each post so the top is rounded and smooth.
7. Put the bridge back on. Done.
(edit - before step 3, cover your guitar top and wear safety goggles. Don't risk damage to guitar or eyeballs)
Took me about 40 min including re-stringing. Made a difference!
You could then go further with something like a Faber bridge that locks onto the bridge posts, so the bridge itself can't move around on top of the thumbwheels. Honestly, I think the original design is pretty shitty by comparison.
Listen to my Les Paul Classic, you can really hear those solid bridge posts
Tracked direct with my AX8 a few weeks before my FM3 showed up.
