For those of you in junior high in the 60's-- did roundwound bass strings come into the picture with Roto-Sound Swing Bass strings?
I believe Rotosound claims to have "invented" the roundwound bass string. I know I first used roundwound strings in the late 60's, before the SVT came on the market but not much before.
Yes, Rotosound did invent the roundwound bass string in the early '60's.
John Entwistle was the first to use/evaluate them (AFAIK).
I've been using RS-66L swingbass sets since 1975 and I change them about every 10th day of use (about 30 hours).
