Kind of a noob thread but here it goes anyway... I recently replaced the tubes in my Crate Palamino and noticed a HUGE improvements in tone. If $80 worth of Mullards can make my amp sound better I started wondering what other mods could make an impovement to tone. I think that a speaker swap would be the next obvious mod that would drastically affect the tone. Aside from tubes and speakers, what are other good mods?
