How does changing the pot help a guitar...

I read that changing the pots and pickups and tuners in the Ibanez RG321 can make that guitar a beast
It will make it look better I suppose >_>
But changing hte pickups would alter the tone. And tuners I suppose keep it from going out of tune hopefully... my originals are fine though.

Gibson ES-335 (Dot)

Epi Valve Junior Half stack
Line 6 Floor Pod (FOR SALE!!!)
Changing the pot of any guitar would alter the sound of your guitar. Just like changing the pickups, changing the pots of your guitar can add or minus certain built in characteristics of your guitar to suit your desired tone. Experimentation is the key here. For me, I choose to experiment with effect pedals as it's less risky and much less costly. Go to www.guitareffectssecrets.andy-ng.com to find out more...
