A great little acoustic amp at a reasonable price!

Are you looking for an acoustic amp that sounds nice, has enough options and provides good volume for smaller venues? Look no further - here's that amp!

This is a 2 channel amp that features Volume, 3 band EQ Bass, Middle, Treble and added Reverb controls.

40 watts. 2.65 inch speakers - Special Design full-range Whizzer cone speakers. This amp is plenty loud in most smaller acoustic and vocal settings provided you're not performing in a larger venue like an auditorium etc.

Accommodates an acoustic-electric guitar and dynamic microphone

Create depth and dimension with digital hall reverb

Auxiliary input, XLR line output, and headphone output

Attractive vintage-style brown textured vinyl covering

I like using this Fender Acoustasonic 40 acoustic guitar amplifier. It is just right for my needs. Its loud enough has good tone and I can adjust how I want it to sound with the 3 band EQ and the reverb is a good touch.

I can use both my acoustic guitar and a dynamic microphone together and get the sounds I'm looking for quickly.

This would make for a perfect practice amp, at home amp, church functions or smaller club venues.

This amp is a pleasure to carry. No breaking your back. Grab your guitar, microphone, cables and this amp and GO.

Height: 11" Width: 15" Weight: 16.5 lbs.

If you're on the fence about this amp -- DON'T BE! Pull the trigger! But do take some time and play around with the settings. I've heard criticisms of this amp and come to find out that the people complaining tried it for 10 minutes or less and never got to know the amp at all.
