I use GHS Pressurewound strings on my L2000. Currently, I have the bass strung with medium-light gauge (0.44, 0.58, 0.80, .102). The action is very good, but I'm wondering if i could set it lower if I went up to medium gauge strings (0.44, 0.62, 0.84, .106). This is the heaviest gauge Pressurewound string. I would need to have the nut filed to fit the heavier strings.
