The AA-40 is a 45 watt single channel Acoustic guitar amplifier. Designed to be ultra portable for the musician on the move the AA-40 weighs in at a tiny 3.4kgs.

A fully featured pre amp allows the user to sculpt their perfect acoustic tones by using the treble and bass eq controls whilst retaining the characteristics of the instrument being used.

Stunning digital Reverb is available in 4 different flavours and a very useful notch filter will help to cancel out feedback inducing frequencies when playing at higher volumes. 

The stunning acoustic tones are delivered via a custom 5" speaker combined with a studio quality tweeter for stunning acoustic tone and projection that belies its tiny size.
