Line 6 spider, heard a lot of bad things about them, but i think some people just have high standards and expect miracles, after all it's a cheap amp, has heaps of features, so it's bound to be a bit flawed.
Personally I would have picked a roland cube over a spider but it might have cost a bit more. cubes are loud as F**k though.
Seems a bit strange that u'd spend so much on a guitar and not spend money on an amp. I mean a mid range guitar through a mid range amp can sound really really awesome, but a high range guitar through a bottom range amp can really be a downer, can really dampen the quality of the guitar.
