Thanks for the nice welcome, just bought a stand-up 4/4 bass for my son, who, in his manic slap technique, has broken two-strings already. I'm having a heck of a time with local music stores finding new strings and was hoping someone out there could clue me in to a good on-line source. Even Musician's Friend hasn't helped. Glad to find this site, will watch closely for help. Dan Lapp
