ya it has 2 power tubes, i couldnt remember if it was a 2203 or 2204, its at the practice space, so i couldnt look. i know ive thought about that, but didnt really want to bring more pedals into the mix, i love the way it sounds just straight plugging it in. by more balls i just mean like taking it that extra notch. a little more gain, sustain, etc. ive looked into some splawn amps, which sound great, and the kerri king 800. which im not a metal head by any means, but ive played that amp before in a guitar center and it sounded great. unfortunately with many of the clubs i play, i cant really turn the volume past two, otherwise my stage volume would be just to loud. i guess something like a tubescreamer would be a safe bet, but i was just wondering if there was something besides like a serious mod that i could do to my head to achieve a but more umphhh.
