My brother in law has this vintage Gretsch he asked for help getting more info on. I’m a guitarist and one of my favorite axes I own is a blueburst Gretsch. Best I can tell from what I have been able to determine it is a model6124 with the hilo’tron pickup. I have had difficulty finding one with this Bigsby. No bridge or pickguard, which vintage parts could be obtained to make it complete. I know these pickups and tailpieces weren’t used until the late 50’s, early 60’s. There is no visible label to id the serial number. Any other info anyone can provide? Value as shown and with a vintage bridge and pickguard? Thanks for your feedback!
