Warwick FNA users! Upper register question.

[gottawalk]

So, I have a stock FNA Jazzman and I have a solo in one of our songs in the band I'm in that calls for it being in the upper register. My drummer has gone out front and says that it sounds "thin". With the understanding that my strings need to be changed, is there anything that you have found that will fatten up the sound in my upper register? Maybe string guage...?
