From Euphonic Audio:

Our three pound Swiss-army knife.

EA makes micro heads for bassists who like to hear their instruments without amp colorations. These pocket-rockets deliver over 500 watts of power, yet weigh just a couple of pounds – an unbeatable ratio.

Among EA’s biggest supporters are professional players who might find themselves playing a 5-string bass guitar on Friday night and an Upright Bass on Saturday. Or maybe both on the same gig. These bassists are called Doublers, and they finally have an amp worthy of their name. Doublers have specific demands: hi-fi accuracy, the power to drive the low ‘b’ on an electric bass or handle the power of a ‘doghouse’ played full tilt, and a series of unique features that allow for the proper amplification of an Upright Bass. Features like a two channel preamp for getting a properly mixed stage sound, with one channel optimized for piezo pickups and one for mics, and a set of filters that eliminate the feedback common to Upright basses.

Amazingly, the EA’s Doubler has all of this, and packs it all in a 3 pound box with over 500 watts of power on tap.
