I'm really liking D'Addario NYXL 45105 strings on my L-2000.I like rounds that are a little on the bright side, but not too bright. These have been great, and they last awhile longer than some others I've tried, such as Ernie Ball and Rotosounds. I'd recommend them.
With my L2K in preamp on, no treble boost, series mode, both pickups on, playing between the pickups, I get a nice fat bottomed tone with a bit of growl, which I really like. For some things I'll use the preamp on with treble boost, series again but only the bridge pickup on, playing right over the bridge pickup with the bass knob rolled off to about 3/4 treble knob rolled off very slightly and the sound is really tight and articulate. Treble boost off, series, and neck pickup only, bass knob dimed, treble rolled off to about 3/4, again playing between the pickups, and I get a sound that reminds me of a P bass.
Point being as related to strings, these handle all settings really well. I'm very happy with them and I'd suggest trying them if you are looking for strings for your MFD beast.
