Fender Acoustasonic 40 Review – The Grab and Go Acoustic Amp

4.7 out of 5 stars

Whether you perform – or will soon start performing – in a church, school or coffee house, the Fender Acoustasonic 40 promises a simple ‘grab and go’ solution for guitarists on a budget. With streamlined features, it’s certainly one of the simpler models on our list of the best acoustic amps, but this can be exactly what’s needed sometimes. Let’s take a closer look.



The Acoustasonic 40 features two channels that can be used for either mic or guitar, with both channels featuring the exact same controls. Working from left to right you’ll find a master volume control, then 3-band EQ (bass, middle, treble) and a reverb control. That lineup is replicated for both channels.



Starting with power, the Acoustasonic 40 features two 6.5” special design speakers with high-frequency whizzer cones offering 40 watts of power. While it won’t be powering bigger gigs, there’s more than enough oomph for coffee houses, churches, restaurants, bars and so on. Plus – if you need a little extra juice – the rear of the amp features a balanced line-out connection.

It also easily adapts to your needs in terms of inputs. The slightly odd-looking inputs for both channels are combined 1/4” / XLR inputs, allowing you to connect two guitars, two mics or – as many performers will appreciate – one of both. There is also an auxiliary input for playing along with external music devices, and a headphone output for quieter practice.

Otherwise this is quite a simple amp, with no bells or whistles. This rings true for the design, which matches the rest of the Acoustasonic Series with a basic but stylish brown textured vinyl case and black grille cloth, as well as a handy carrying strap on the top.


All in all, the Acoustasonic 40 performs very well for the sub-$200 price tag. As we’ve mentioned, it’s only suitable for smaller rooms as the output won’t fill much more than a small hall. Tonally, it delivers a very clean and organic sound that suitable for many acoustic styles. The simple EQ controls allow for easy adjustments on the road with the reverb a highlight – especially the fact that you can individually adjust the ambiance for each channel.


There are certainly more powerful and more versatile amps out there, but the Acoustasonic 40 does the basic things very well. At under $200, it proves a sensible purchase for guitarists wanting a lightweight, portable amp that’s flexible when it comes to inputs.

    Can I use the mini-jack auxiliary input at the same time as using the guitar and microphone channels?

    I’d like to play a pre-recorded backing track along with my performing.
