Which amp for a post-metal/sludge ?

Well I think apart from my amp, my guitar could do with a change also. I have an Ibanez SA260 with a Bareknuckle in the bridge.. but the bareknuckle is a bit too bright, and when I roll off with the tone control, notes then lose their attack and sustain. I was thinking of replacing the guitar with a Les Paul, but I'm not sure I like them. Tried a few, and they felt very odd to play. Don't know if I could get used to it.
 
My first electric too ;)

Y'know what.. I'm gonna do it.... I'm so tired of not having a great guitar. I go to Japan in a month. I think I'll try and get a MIJ Tokai whilst I'm out there.
