The Zoom G5 was one of the most comprehensive effects and amp modelers available at the time it was released, with an onboard 12AX7 for real tube warmth and lots of digital processing power. It can emulate 123 effects and 22 different head and cab combinations. Up to 9 effects can be used at once, with over 250+ memory presets and USB connectivity. A 60-second looper tops off the package.
