A Stellar Acoustic Amp - and More!

Fender's Acoustasonic 90 Combo acoustic guitar amplifier has all the features you need to get through any acoustic gig in style. The Acoustasonic 90 Combo is perfect for singer/songwriters too, thanks to its separate microphone and instrument inputs. You can plug in both your instrument and a microphone, for an instant solo PA. Or, plug instruments into both channels. You get great-sounding effects, and a balanced line out for more flexibility. Feeback-elimination controls keep the 90-watt Acoustasonic 90 sounding great even at higher levels.

Fender Acoustasonic 90 Combo Acoustic Guitar Amplifier at a Glance:
  • Clean, clear performance for your guitar and vocals
  • Solid tone and rugged durability from hardwood construction
  • Gig- and recording-ready features
Clean, clear performance for your guitar and vocals

Fender's Acoustasonic 90 Combo gives you 90 watts of powerful, clean performance, in a surprisingly lightweight (only 18 lbs.) and compact package. But, that's just scratching the surface. Factor in the onboard effects (including chorus, delay, reverb, Vibrotone, and more) and super-handy feedback elimination, and you've got a very convenient guitar/vocal amplifier solution with the Acoustasonic 90.

Solid tone and rugged durability from hardwood construction

Even though it's lightweight, the Fender Acoustasonic 90 is rugged. It's made from five-ply hardwood, which also gives you solid tone and cuts down on cabinet resonance.

Gig- and recording-ready features

Plug both a guitar and a microphone into the Acoustasonic 90 amp and you have an instant solo PA. This 2-channel performer gives you independent control over each input, so you can balance your vocal and guitar (or balance two instruments) perfectly. Playing bigger stages? You'll love the balanced XLR direct out, which lets you use the Acoustasonic 90 as a monitor while you pump your signal out to the house PA.

Fender Acoustasonic 90 Combo Acoustic Guitar Amplifier Features:
  • Rugged yet lightweight acoustic instrument/vocal combo amplifier
  • XLR combo input on channel 2 lets you plug in a microphone or an instrument
  • Five-ply hardwood construction reduces resonance for solid, powerful tone
  • Built-in effects, feedback eliminator, and direct out, for great live performances
  • 8" speaker and 1" piezo tweeter provide well-balanced frequency response

Fender's Acoustasonic 90 packs an incredible array of features and sonic capabilities into a very portable acoustic amp!

A great tool

The quality of the product is top notch but even more important it sounds great. I played an electric guitar and hooked up a mike in my studio and every one thought the vocals was coming from the studio monitors. It sounds that good. I had to prove to my friends that the pa was off. Again the unit itself is solid and it sound great.

I had to wait several weeks as it was on back order but man, glad I waited, Amazing little amp with power and a sweet sound. Get the foot switch.First time I lifted up I thought they only sent the box-no guts! Played for a house of about 200, cranked about half and was heard. Haven't fooled too much with effects but in preview was impressed and defiantly will for chorus and guitar solos in songwriting gigs. f you get a chance try one out. If you can't find one just buy it-you won't regret.

Great Amp

Yes. I am blown away. I have been playing professionally for over 40 years as a lead guitarist and really never played my acoustics as much as I should (Guild D25 "84" and a Yamaha 500. Mainly , because they don't fit our show. Lately, I have had the urge to dive deeper into the acoustics, but never liked the amplified sound. I saw a Youtube demo describing how the acoustic amps were different than just an electric guitar amp. I did not know this.. I watched and studied the demos in every detail in respect as to what I thought I really needed to hear in the effects department, weight, size, and also the other options such as inputs, outputs, etc. The more I read the more i wanted to hear one of these amps. Honestly, in the back of my mind, I felt that was going out on a limb, because I don't like buying stuff I don't use. However, I pressed forward and looked at every acoustic amp on the market for under $400. I actually made my mind up several times on different amps other than the Fender, but I would not buy. Something told me I was not ready. I just held on. I was really confused. I use a "72" Pro-Reverb on stage and as far as I'm concerned there is not a better sound. So, with that in mind, I knew Fender and I knew Fender was going to do their homework on the Acoustic amp. Too, I knew the resale would be there if I didn't like it. I guess that was my final tilt toward the amp. I did have a budget, though. I wanted something under $400. We have a great PA so I figure if I did take it to the gig, I would mic it. Finally, I said "enough". I called Sweetwater and they made me a deal. I ordered on the spot. When it came in I was still worried that I may have bought something that I could not noticeably hear. Let me tell you. I was Blown away! I played for an hour before I took a break. The sound WAS different. Not in a little way but a BIG way. I am Big-time satisfied. Very! So, acoustic players, if you are using an electric amp with an acoustic... stop now and buy a FENDER Acoustasonic. You will never regret it. Somehow I made the right decision.

Acoustasonic rocks!

Yup ... I did it again. I was so impressed with the first amp, we went ahead and bought a second one. Who needs to haul around a mixer, speakers, and stands for an acoustic duo? Not us! Again, the Acoustasonic is powerful, comes with needed features and it sounds GREAT!

GREAT little amp!

Used this tonight for the first time at a gig. Can't believe the sound quality! The Gibson J45 sounded very natural, and the vocal was loud, clean and clear. The effect used tonight was a slight delay on the vocal and it sounded great. Lots of useful features and the clincher .... 18lbs is all it weighs! I may just sell my Genz Benz and buy another one of these for when I'm doing a duo with my wife.
