When I bought my RG 3xxxx the previous owner had 8's on it and the setup was perfect so I never tried anything else. Now that I'm used to this setup I'm noticing there are some definite advantages to the lighter strings. For one theres a nice brilliance to their tone that seems to go well with humbuckers. At least as far as clean amp sounds are concerned. Second is good tuning stability. Maybe a result of the lower
string tension? And last whats really cool is what appears to be excellent intonation across the fretboard. Makes adjusting the saddles a breeze.
I still prefer the feel of heavier strings but would rather find a different guitar for them than change this one.
