Hey Everyone! New poster to the board. I'm looking at buying a used (2 hours total playtime) Blues Jr. in Lacquered Tweed. It's a PR 295, and the serial number starts with B-7*****. The seller is not sure whether or not it's a BJR 3 or 4, and says it has a "gold" speaker in the back, but doesn't know what make the speaker is. anyone here have any idea what I'm buying? Is that the Jensen c12q in the back? a Celestion? Thanks!
