a processor sure isn't going to add any 'balls' to the situation
Plus your bedroom tone must be completely different from your stage tone.
When you play alone in your bedroom there's no bass there so guitarists used to add too much bass too make it sound fuller.
Guitars are mid range instruments like human voice,at the stage if you add too much bass it'll embrace bass and kick drum and everything will sound like a mass.
At the stage less bass and more mids can give you more balls.
But if your amp doesn't has enough distortion,buy an amp that has all distortion you want.
That's why I love mesa boogies,without any pedal I can play from clean to death metal,I don't need boosters and distortion pedals.
You could buy a mesa boogie dc-3 or dc-5 amp on evilbay.
They're pretty cheap these days.
They have awesome cleans and powerful distortion.
DC series came right before Mark series.
I have my dc-3 for about 12 years and I'd never sell it.
Well just an idea.
