I recently acquired an almost new old stock 90s ibanez SR400, and because the frets are immaculate I would like to try a set a flatwounds to minimise wear. Now I am looking for the right tension/gauge, but the trouble is I have only played a handful of basses and aren't really familiar with the gauges and tensions. I do have a rough idea of what I like and don't like: I tried the Ernie Ball 50-105 roundwound gauge on another 34" bass and didn't like it that much - a bit too heavy. However, I also recently acquired a cort A4 34" with a really nice gauge on there - trouble is the person I bought it from had no idea what gauge it was.. It has gold ball ends so I'm guessing it may be Ernie Ball? Possibly 45-95 or 45-100 roundwounds? Other than guessing I have no idea of finding the precise gauge. I suppose that means I am looking for a low-medium tension set of flatwounds? Does anyone know what gauge I should be aiming for? (I also want to keep the nut stock on this bass). I was thinking possibly 40-100 chromes or something like that? Would that be the sort of tension I am chasing providing my guestimates about the string gauge/tension on my Cort A4 are correct?
