A Grab-and-Go Acoustic Amp That Does Double Duty
You've got a gig at the coffee house, an open mic, or a backyard cookout — and you need an amp that fits in your trunk, runs itself, and handles both your guitar and your voice without a separate PA. That's exactly the problem the Fender Acoustasonic 40 was built to solve. Grab it by the molded plastic handle, plug in your acoustic-electric on channel 1 and your mic on channel 2, dial in a little reverb, and you're ready.
Two channels, 40 watts, and a pair of 6.5-inch full-range speakers make this amp a genuinely flexible small-venue solution. It covers the basics with a 3-band EQ on each channel — Bass, Mid, and Treble — so you can shape your guitar and vocal tones independently. The vintage-style brown textured vinyl covering and black grille give it a classic Fender look that fits right in whether you're on a stage or in someone's living room.
If you play acoustic-electric guitar and occasionally sing, or if you just need a clean, lightweight amp that also works as an onstage monitor when you're plugged into a bigger PA, the Acoustasonic 40 is worth a close look.
The Whizzer Cone: An Unusual Speaker Design Worth Knowing About
Here's a detail that sets this amp apart from almost everything else Fender makes: the Acoustasonic 40 uses a "whizzer" cone — a small supplementary speaker cone attached to the voice coil of each 6.5-inch driver. Fender notes it's the only guitar amp in their lineup built this way. The purpose is better high-frequency response without a separate tweeter, which keeps the cabinet compact while still reproducing the full brightness and string detail of an acoustic instrument.
For acoustic-electric players, high-frequency clarity matters. An under-saddle pickup or soundhole transducer captures a lot of pick attack and string texture — details you want to hear in the room. The whizzer cone design is a practical answer to that need in a small, lightweight package.
Two Channels, XLR I/O, and Real-World Connectivity
Each of the Acoustasonic 40's two channels has its own combined XLR/1/4" input on the front panel, a full 3-band EQ (Bass, Mid, Treble), and independent reverb. This means you can run your guitar and a microphone at the same time, each with its own tone shaping — a genuinely useful setup for solo singer-songwriters without a separate mixer. The instrument channel's reverb adds ambience for the guitar without necessarily affecting your vocal channel the same way.
On the back, a balanced XLR line out with ground lift lets you send a signal to a front-of-house PA or recording interface cleanly. There's also a 1/8" auxiliary input for connecting a phone or media player, and a 1/8" headphone output for silent practice. The cabinet itself is built from 5-ply 5/8" lightweight plywood — sturdy enough for regular transport, and at 16.5 lbs., genuinely easy to carry.
