Yeah, I LOVE the Les Paul Sig Bass. It's my fave longscale hollowbody.
As far as the 6-string. I used to be a ES-345 guy for decades but once I discovered the Les Paul Sigs my loyalty changed. My pickguard on the 6-string is actually signed by Les Paul.
I actually had a pair of sunburst ones...Seal's guitarist bought my spare but then started hounding me when he heard I have one of the only two black 6-string ones as well. I told him there was no way I would sell it but he kept calling/emailing and jacking up his price ($6,500 last time)...but it is still here
I got it from the original owner, a former Gibson Kalamazoo longtime employee/luthier who custom ordered it and also had the hardware changed out to gold at the factory...even had them add one of those old Gibson "Custom Made" black plastic plaques between the bridge and tailpiece. He also said he had them do extra coats on the paint when it was painted. The bnding is really yellowed out...look waay cool. Killer guitar.
You don't run across many guys who use them. Besides Jack Casady, I recall the bassist in LIVE had a sunburst bass like mine he used. Jacob Dylan's guitarist also used one for years in the Wallflowers.
That pair of gold ones above is NICE! I think you were wise to turn down $5,000. I've seen clean ones go for more.
