This is a question for owners of the Star 5 and prior owners of the Star 3. Q1: If the string bed tighter on the Star 5 than the Star 3, if both are strong at the same identical tension? Q2: My Star 3 seems to hold calibration very well. Is that true with the Star 5 as well? I think Albert Lee has both of these machines. I'm sure there are other stringers too.
