Hi I bought DR Low Rider 40-100 guage only about 4 weeks ago, already the G string has snapped. I need new strings to buy tommorow in Glasgow so they have to be avalible in shops there. I play slap bass and songs like Teen Town by Jaco Pastorius and various others including movie soundtracks, Willie Nelson etc. I also like tapping. What are the best types of strings I could buy for my 4-string bass?
