As far as amps go, I'm there with my new Mesa Express head (unless I decide, in a year's time, that I'm going to play nothing but black metal, and go on tour).
Pedal-wise, I'm not done, but i know what I want - a BB Preamp, a Radial Plexitube, a ZVEX Box of Metal, and a Keeley compressor. Oh, and a hard bypass md for my wah pedal.
Guitars - no. I'm happy with most of what I have - I'm still totally undecided on what to do with my Holy Diver loaded PRS SE Singlecut, because I've been so busy I haven't even had a chance to play it through my new amp yet!
However, my Epi LP will go at some point. The LP is a very dark sounding guitar, even with a set of Mules in it, and doesn't really sing as it should. To replace it, I'll likely look for a good second hand Gibson, so I can drop the Mules straight in, or a PRS SC245.
I also really want one of the new rosewood necked PRS Custom 24s. PRS guitars, as several members on this forum will attest, are viciously addictive. So, the GAS isn't gone, but it's not too bad right now.
