Use it both through the computer (I got the G2..not the G2.1u) and through a Marshall 2203 resissue half stack. Sounds great through both, records well (use it to do bass from my 6 string using the pitch shifter) and it sounds excellent through the Marshall. Useless for live situations through because of the limitations of it's patch switching system. If you like the sound of the G2, suggest you look at the G7.1ut or the the G9.2tt
