The first thing you notice about Orange Micro Crush PiX amplifiers is their cool looks. Just like their bigger brothers, they have the legendary Orange Basket Weave Speaker Grille and of course the Orange signature "picture frame" edging. But it"s not just cool looks... Plug into any of these great little amps and you"ll soon realise they are Orange through and through! Operates on 9v battery (not included) or 12v power supply(included). Comes with guitar strap buttons (requires installation) so you can wear it. In order to conserve battery life, this amp will not work unless a 1/4" cable is plugged in.
