Really Expensive Binder Twine
I've been using Elixer acoustic and electric guitar strings for 10 years now. So I thought to myself, "Elixers have to sound great on my Fender Elite Jazz bass." Wrong! These are the worst bass strings I've ever tried.
Right after install, they were so bright and metallic sounding, I couldn't use the bass live or in recordings. So I gave it 2 months of break in time (with about 20 hours of playing). While the brightness came down some, the metallic 1.5 kHz to 2 kHz brashness is still there. Even worse, these strings are very microphonic.
And then there's the price... it's higher than good sounding strings.
I will note that the coating takes the sliding finger squeaks down considerably.
Don't waste your money. D'Addarios, Fender, DRs, Rotos, or even cheap store brand strings sound better.
Don't buy these.
