The Acoustasonic 40 is a portable acoustic amp that's designed to work well with both acoustic-electric instruments and dynamic microphones.

It sports a 2-channel 40W solid state amplifier section that drives two 6.5" full range cone speakers.

Each channel has dedicated 2 x XLR-1/4" combo inputs, allowing you to plug in a guitar and a mic at the same time.

The two channels also have volume control, 3-band EQ and dedicated reverb control.

Finally, it has a headphone out, XLR line out and an Aux input.

Owners are pleased with tone and volume, especially when considering its size. They are surprised at how loud it can get, being able to fill venues that they thought it couldn't. Others point to its clear sound as its main strength. While many reviewers got this as their first acoustic amp, there are also plenty who got this amp as a viable portable substitute to bulkier amps.


There are those who wish for more low-end, but this is more of a limitation due to its smaller speaker size than a problem.


If you're looking for a portable and affordable acoustic guitar amp that can be plugged into a PA system when needed, then this is your best bet.
