Been trying so many makes and expemnsive coated and special strings to get that exact sound i wanted from my Gibson guitars, bought a load of Roto sound strings as they were cheap and im wanted to get the guitars all with new strings, i was mazed at the righ tomes and sounds comming from my guitars with the Roto soun strings, thay have improved vastlky since trhe last time i used them 20 plus years ago as a budget sring, no more , they are my strigs of choice now to get the best sounds out of my prized Gibson guitars and valve amps.
