Buckethead is mentioned on Tdrsmusic as having used a Gibson 1968 Les Paul Goldtop, along with a black Telecaster.

He talked about this guitar in a Gibson article.

“I’m still looking for a ’68 Goldtop. The first Les Paul I bought was a ’68 Gold top. Now that’s a sought-after Les Paul, but I only paid $300 or $400 for it at the time. I’d love to have that guitar back — especially looking like it did before I scraped the gold off of it. I’ve got a couple of Goldtops that are close, but that particular guitar is the one. One of the rumors is that after they stopped making Les Pauls in ’60 or ’61, and then started making them again in ’68, Gibson had a lot of parts left over. If that’s true, a lot of those pieces of wood were just sitting around the factory and got used. And the pickups were great.”

In this post deryk talks about the 1968 les paul gold top he bought. He states that this guitar was bought from producer Michael Beinhorn. This guitar was used to record records for artists such as Ozzy, Manson, and social distortion. He states that social distortion was one of the bands that changed his life. The guitar is “more like a 50s in disguise” because of how it was made. Gibson stoped making les pauls in the mid 60s but then started making them again in 68

Rich Robinson used a Gibson 1968 Les Paul Goldtop with a Bigsby vibrato for the album "Shake Your Money Maker," as detailed by Pete Prown in Vintage Guitar® magazine.

Two of Tom’s main guitars: a 1968 Gold top. Initially fitted with two P90 soap bar pickups, It seems shortly after purchasing this guitar, Tom had routed out the P90 cavity and installed a Super Distortion Hum-bucker in the Bridge position. He refers to his #1 Les Paul as “Mighty Mouse”, after stripping the gold finish and applying a Mighty Mouse decal. His other #2 1968 Gold Top has two Dimarzio Super Distortion’s and its gold finish remained.

I’ve included a rare shot of him playing it before its transition to Hum-buckers.

"We were kind of replicating personality-wise some of the stuff we did in the '70s. I used to have a '68 Les Paul goldtop P-90 guitar that ended up going by the wayside. I've looked all over to try to find a substitute, and I managed to find another one up in Boston. That guitar was a real go-to for the album."

"That was one of those that I picked up kind of early in that stage (when) I spent a little more money on (guitars). And that, again, was a ’68 Gold Top that got routed out for humbuckers and I threw ’59 PAFs in it, and it is a beast." - Aaron Lewis in this article from Gibson.

Jeff Cease used the Gibson 1968 Les Paul Goldtop, the same guitar that Rich Robinson utilized for much of the "Shake Your Money Maker" album, as confirmed by Pete Prown in Vintage Guitar® magazine.
