Hello i made a short sample of my g2, recorded with tone 60% and volume 45%...
the guitar its a ibanez AFS75 and a AKG c3000 microphone directly to celestion 10 speaker...a beringher eurodesk mx9000 mixer and a very cheap imic to tranfer the sound to my mac mini.....
im a very bad guitarrist 
but you can listen the sound of the g2...
