Fender Acoustasonic 90: Looks & Layout

The Fender Acoustasonic 90 is extremely compact at about 15 inches tall by 19 inches wide and 10 inches deep. This behemoth has a wood case with brown tolex and sharp silver corners, inside are two drivers – one 8″ speaker and one piezo horn. The audio playback quality of this device is fantastic. All the controls are on the front of your amp with a built-in microphone input that functions as a PA. The controls feel pretty rugged and seem like they will be able to handle some tough conditions.

With its tolex-covered and brown control panel, the amp is a retro piece of gear. But this 90 is still a streamlined amp which comes with all the benefits of the 150 without all that extra weight.

The 90 has a bit less power (90 watts as opposed to 150) and does not come with the Voicing and String Dynamics controls, round tilt-back legs, or the effects loop on the front panel. It also doesn’t have a USB port or rear panel.

The layout of the Fender Acoustasonic 90’s control panel is uncluttered and user friendly. There are two separate channels. The first accepts a quarter-inch instrument plug while the other accepts either an instrument plug or an XLR mic/instrument jack, with phantom power available.

Each channel includes:

  • Volume control
  • Feedback-elimination button
  • Treble, middle, and bass controls
  • Knob for accessing a selection of time-based digital effects
  • Knob controlling their level.

The amp’s power switch is on the back by the XLR ports. It also has a footswitch input for when you want to turn it on without using your hands and a ground-lift button.

Although I would have preferred a volume control included, the 90 version includes something missing from the more expensive 150 model: an 8th inch auxiliary input which you can plug in your music player or phone.

Fender Acoustasonic 90: Channels and Controls

The Fender Acoustasonic 90 is a 2 channel amplifier with your standard EQ arrangement of treble, mid-range and bass. The first channel is for an acoustic guitar and allows you to shape your tone.

But there’s also an effect on each configurable channel that provides nice extras like reverb, echo, chorus and other effects.

There’s also a feedback-elimination button each channel that is designed to prevent feedback once sound is playing at higher volumes. The speaker just made a bold statement and they know it!

Putting Channel two through PA duty is super easy. You just need a microphone and you can use the 1/4″ or XLR jack. It’s a really versatile amp and it can be used for vocals as well as acoustic instruments!

Lastly, you’ll find a FOOT SWITCH JACK on the rear and an XLR for direct OUT. This provides more features should you need them!

Fender Acoustasonic 90: Output Power

The Fender Acoustasonic is rated at 90 watts and is very capable of getting there!

I found that this worked for different sounds…

The sound quality on this amp is fine given the types of settings it would be used in and I didn’t have any issues at higher volumes.

Fender Acoustasonic 90: Microphone Performance

What a great thing we discovered, huh? We added a microphone to the channel, which was fantastic. It sounded 10x better than we had originally expected.

When playing an acoustic guitar and singing, it’s important to have a heavy-duty amplifier for the clearer sound. This one delivers plenty of volume for that type of gig!

Fender Acoustasonic 90: Sound

It felt like the fender team hit it right out of the park when they designed this acoustic amplifier! The moment I started my acoustic guitar through it, I was lost in how nice it sounded.

With no EQ tweaking, the sound quality was great and it sounded very well. I cranked my amp up real high and engaged the feedback control circuit – got great sound!

Channel two is fantastic with a microphone and sounds even better than on channel one. The amplifier provides a clear vocal sound that’s way better than channel one. This machine definitely deserves the top shelf!

I can’t believe how this amp is both powerful and good-sounding for only $500. The built in effects are also awesome and make either an electric guitar or vocals sound great.

I know what you’re thinking, but I want to reassure you that we tested the amp with an electric guitar too. With a Telecaster going into the input, the amp sounded great!

We started pushing the input a little more, and got a bit more volume out of it. The telecaster sounds great through this amp. It’s a really neat amp for solo work or just playing around for practice, especially if you are doing solo work or any kind of improvisation.


Fender’s Acoustasonic 90 is a streamlined version of its top-of-the-line 150, costing $200 less than that amp, but sounding just as good. This less powerful amp is specifically aimed at acoustic guitarists who also play electric guitars.

It’s small and lightweight, yet it produces tonnes of sound to fill a decent sized area. We love the factory presets for acoustic guitarists so you don’t have to adjust any settings.

There isn’t a lot of great gear out there for acoustic players, and even less that sound just as good on a professional level. The Fender Acoustasonic 90 is an amp from Crate that does both, but finding one can still be somewhat of a challenge.

The Fender Acoustasonic 90 really impressed me, it is capable of providing some great tones and effects! It also features a microphone input which is quite cool, so don’t forget about it. For beginners learning on an acoustic guitar, this amp has you covered!

With a DI jack on the back, this amp is perfect for those who play small gigs. Not only is it great for live performances, but it can also be used with a footswitch which offers an added level of versatility.
