I bought a set of Labella new old stock guts and only used the plain guts. These are old strings; I soaked them in olive oil overnight before putting them on and didn't have any problems with them. At any rate, I play all guts and can't use the wound E and A outta the set; they've never been on a bass and are still in "as new" condition. I'll take 25 bucks each for them and buyer pays shipping. Thanks folks.
