I don't know about the jigmaster but I have a 3/0 & a 4/0 pen senators that I got in 74/75 that work like they are still new .a little ruff on the out side but still smooth on the inside . both have been used hard broke a few rods with each on . bottom fishing and trolling use to have different rods for both reels depending on what I was fishing for . I have a 209 pen reel the same age I stacked blocks for my uncle all summer to make money to buy them .when he got paid for the job and was paying me he ask what I was going to spend my money on I told him the fishing reels that I was talking about all summer he laughed and said don't waste your money and said go buy rods then gave me the brand new reels
