So I've had my Kay since February, and I'm still having a lot of trouble getting a good attack out of the E string. I've been doing a little poking around and found out that the set that's on there has an E string that's .15" thick!!! As opposed to other strings that seem to run from .1 to .12 ish. So it's not JUST my deficiencies as a noob upright player (been playing electric for 7ish years, and discovered that electric in jazz is kinda lame). The other strings are pretty manageable, it's really just the E that's killing me. Would you recommend I only switch out the one string and save some money, or go all out and get a new set of lower guage steel strings? In the case of the latter, which strings have lower tension, light guage, and a bold sound for jazz?
