I’ve just forked out for some elixir nanowebs, not cheap (£40) but they are supposed to last 5 times as long as regular rounds, it’ll be interesting to see how long they do last, they’ve been on my p bass for about a month now and show no signs of aging or dullness. Trouble with cheap strings ( and I’ve tried loads, thomman, status, warwicks, legacy etc) is you do kind of get what you pay for, my regular gigging strings are now DR high beams which are just superb but do cost, done maybe 20 gigs and 10 rehearsals with the current set, still sound fresh.
