Does it seem like the strings that come on the bass could be some sort of D'Addario XL? Rondo used to say that.
I can't say who made those strings that came on the bass, but one thing I CAN say is they sure don't sound like a new set of D'addario nickel XLs! No way! For one thing the XLs are about twice as loud! Same with the GHS flats. I mean what kind of string set can you put on a $150 bass and still make a profit?
