The Fender Acoustasonic 90 Acoustic Guitar Combo Amp is an incredibly lightweight and portable package that will deliver the tone you need to cover any performance situation. Guitarists no longer have to put up with the limited mobility of having to stand still in front of a microphone pointed at the soundhole. Now, you can just plug in, turn it up and move freely, without losing your amplified tone.

With 90-watts of power pushed through an 8” cloth-surround low-frequency woofer and high-frequency tweeter, the Acoustasonic 90 packs stage-worthy performance into this lightweight combo. The dual channel Acoustasonic 90 features two inputs, one 1/4" for your acoustic guitar and one XLR / 1/4" combination jack which will allow you to plug your mic right into the amp. Both the 1/4" channel and microphone channel feature independent EQ and effects controls, making for simplistic tonal shaping for both your vocals and acoustic guitar.

The Acoustasonic 90 houses studio-quality effects that are specifically voiced and optimized for acoustic guitars including Reverb, Echo/Delay, Chorus, Vibratone and More.

Every musician dreads the feedback that may occur when using an acoustic instrument or when using a microphone, so Fender designed this amp with that in mind. The Acoustasonic employs a smart feedback elimination circuit with an on/off switch for each channel. The Acoustasonic also features an auxiliary input, allowing you to plug your media player right into the amp, and a soundman-friendly XLR line output with ground lift.

The Acoustasonic 90 is not only performance worthy, but extremely durable and roadworthy, which is perfect for the gigging acoustic guitar player. The cabinet is crafted from 5-ply 5/8" lightweight Hardwood with brown textured vinyl covering and a black grille cloth, giving this rugged amp the classic fender look.

Great AMP!


Great warmth, full sound, great for home use. All the effects are fantastic! Can't wait to get it to the coffeehouse...Only gripe is no headphone jack but that is easily compensated for with volumn control.

"Great portable amp"


This amp sounds great. If you want effects, you got em! If you are looking for straight acoustic sound, no problem, its there. Have only played a D35 and a 5 string with a EMP pickup installed and they both sounded natural and clean. Only wish it had the capability for headphones. Have not tried the microphone side yet, so can't comment on that. Great little amp.!
