It's really important to create your own sound. This is a part of the process I really love the most! Playing with special effects, amps & different sounding guitars. I usually find the nearest preset to the sound I have in mind, then start tweaking until it's unique-sounding enough to my ears. Effects are usually more subtle when you play finger styles.
Today I'm using this Ibanez Joe Satriani signature. It's a great looking guitar and very easy to play. For a heavier song I prefer a Gibson, but they're really heavy to wear onstage all night so I'm looking for alternatives.
