I am courious your view of the LV-03R!  If any, what changes would you make to it? :GRN>

The LV-03R is an incredible sounding and great looking guitar with a sweet sound across the strings.  Changes?  A bone saddle from Colosi and D'addario EJ16's make the guitar very happy.

No modification on my LV-03R and it's very happy :GRN> I once tried FWI and the LV-03R hated it.

Planing on changing the plastic pins for ebony ones. Not for the tone (I hear it doesn't affect the tone much) but rather for look.

Other than that, I have a set of EJ16s which is about time to put on.

I would change the back and sides to mahogany, and do away with the cutaway :TON>

I've an LV-09 - couldn't be happier with it. I doubt you'll need to do anything to yours, but you might want to try a bone/FWI saddle. FWIW, I think the ebony bridge pins look nicer. If you also went with a bone nut (negligible tonal difference though), you'd be at 09 spec.
I guess you could gloss it up too, if you wanted to go the whole hog (search Orsonising).
String wise, I'm really loving Newtones (otherwise I'm an EJ16 type guy). I've settled on 12-56 as I do a lot in low C tunings.
If you're looking to spend money, how bout a dual source pickup?

My main guitar is a 2004 LV-03RE (B-Band A2.2).  I bought it new.  Shortly after I received it I replaced the bridge with a Bone Bridge.  I am thinking of replacing the plastic pins with Bone or Ebony pins.  I've used Medium Strings 13-56 (which did not work for me on this guitar), then I installed Elixir Lights 12-53, which are decent.  I just bought 3 sets of Elixir Phosphor Bronze C Lights 11-52 and wonder if I should have.  I have not yet, other than at home, used the guitar plugged in.  I want this guitar to be the best it can be.

Elixiers nonoweb does it for me.
If you want THIS guitar to sound it's best, play play play it. The more you play it the faster you can break it in.
