I just got my 3 LP set called "The Bass" courtesy of a friendly TBDB'er and our helpful classifieds. The cover, (which I'm scouring the internet for a .jpeg of, but so far, can't find one) features a bassist in thumb position from the tailpiece up to about the neck join. I don't know who the bassist is. It is a non-adjustable bridge, no pickup is evident, there is a rubber mute on the A and D strings between the bridge and tailpiece. I don't know when the picture was taken, but the copywright on the set is 1974 and the bassists's watch and cuffs look about right for late '60's/early 70's. The set is on the CBS/IMPULSE! label. The strings are metal wound and look a little big heavy in gauge, but not overly so. The tailpiece silks are solid royal blue. Never seen that before. Any ideas? I've very excited about hearing these records and am only trivially interested in the strings, but I am into the string trivia, as you know. Would also love to know who the bassist is, but that's probably a reach. I'll read all of the liner notes, maybe there's a clue in there.
