Currently I have my Stingray 5 strung up with LoRiders, 45-65-85-105-125. I feel that the B string is a little floppy and the tone is somewhat undefined. Do you think this is: a. A problem with the string b. A problem with my setup c. Just me d. How it's supposed to be and I should move up to a 130 B If it's a defective string how would I get a replacement, being in Australia? And also, what string gauges do you guys use on your Ray5s?
