I have the new Boss GT100 multi effects and amp modeller unit.
Awesome, fully customisable and whatever effects chain and amp models you like.
Into it goes my MIJ Fender Tele and a '74 Fender Twin Reverb.
Aux in to the GT can be midi, PC , ipod, mikes (phantom power)you name it.
Output to Amp, PA, phones, mix desk
Far more gear than I am capable of using properly :
Roland product demo guy, Josh Munday knows how to show it off though:
