Two Permanents, the G string and the D string, are up for grabs. I had them on the bass for 48 hours; they're actually quite nice strings, but they don't match up well with Spirocore mittels on the bottom. (the volume/punch disparity is a little extreme...) The D-string in particular would be a great substitute in a set of Spirocore weichs for those looking to play some arco (it always seems to me that the Spirocore D in particular stands out as the most strident), but note that these Permanents are a bit stiffer than weichs for pizz work. I paid $75 (!) for the two of them; that's the last time I shop locally for strings...Make an offer and I'll cover domestic shipping. You can email me directly at email@example.com, and if anyone wants to trade new-ish spirocore weich G and D for them that would be swell. Thanks!
