I strung and setup the 594 with 9-42s last night - I'm likin' the feel, so easy to play, although I also
tend to pull the bass strings out of pitch pretty easily. Lighter touch will solve that.
Clean, there's possibly a tone change going from 9-46 down to 9-42. It's actually pretty hard to tell.
Chords may be a little more defined with the bass notes ringing clearer, and maybe not as thick, but single string on E, A and D I dunno...
Same with OD, difficult to tell a difference. More of a feel thing.
I'll play them for a few days before deciding, but so far the increased playability is going to offset any small perceived trade off in tone.
