I have a Plain Top R8 that I love, but in this case I’d go with the Heritage. The fingerboard on the R8 is terrible, as are the inlays. Tough to beat the Lollar Imperials on the H-150 too.
On a related subject, I recall Pete Moreno (RIP) telling me that when he was fairly new at Gibson they had him haul a pickup load of stuff out to the landfill in Kalamazoo. Included were multiple bulk packed boxes of PAF pickups that were somehow deemed unacceptable for production. @brentrocks may have heard him tell the same story. I shudder to think what these would be worth today.
My old H-137 had Lollar P90s. Too “polite” for me. Wonderful HiFi sound, but they didn’t punch very hard. I prefer the Gibson variety.
edit: Lollar has multiple winds available for their P90s. Truth be told, I don’t know what they were.
They need to resurrect the H-516. Gimme that with a fat neck and some P90s. Jazz, blues, rock, country. It would be a do it all guitar. I’m convinced it would sell for less than $13k.
Now retired and sneaking up on codger status, I find myself yearning for an arch top of some flavor. I used to have an H-550, but the neck was mighty thin. Did Heritage ever do an arch top of any size with a girthy neck? I’m used to 50’s style carves.
