Pint-sized Flawless Acoustic Amplification by Fishman

The Fishman Loudbox Micro acoustic combo amp packs the winning feature set and fidelity of a much larger Loudbox combo, but this is the most portable Loudbox yet! With a weight of just over nine pounds, you can easily carry the Loudbox Micro using only one hand. Once set up, it delivers up to 40 watts of punchy power. The Loudbox Micro's main channel facilitates amplification, EQ, and reverb/chorus effects for an acoustic guitar. Amplification experts here at Sweetwater readily vouch for the acoustic channel's built-in preamp and flexible tone controls; versatile 3-band EQ offers countless ways to shape your guitar's character, which means makes it easy to achieve a rich, authentic sound with practically any acoustic-electric guitar, regardless of its body shape, tonewoods, or other variables. The Loudbox Micro's second channel lets you connect a microphone for vocals (or you could mike up a pal's acoustic instrument for a jam session duet). Lastly, an Aux input and an XLR DI output extend utility even further by letting players patch in backing tracks or send signal to house systems, audio interfaces, and more — all incredible ways to enrich your musical world.

Famous Fishman quality

Larry Fishman has developed a reputation for designing some of the best amplification devices in the field. Fishman amplifiers are known not only for their exceptional amplified tone but also for their durability and reliability — traits that have placed Fishman products in the hands of some of the most renowned players on the planet. In the Fishman Loudbox Micro, he has designed an amp that's powerful yet naturally portable, much like a great acoustic guitar. This amp is lightweight, but the sound will blow you away. The secret is great drivers, and the Loudbox Micro features two of them: a 5.25-inch woofer and a separate 0.8-inch tweeter. Together, these drivers make the Loudbox Micro much more than just a loud box. You get lows that sound warm and round, while highs are crisp and clear. This is portable amplification at its finest.

Professional sound meets intuitive controls

Premium mixers and preamps sound are a big part of the enduring credibility the Loudbox series has with performers. The Loudbox Micro offers robust level, gain, and EQ controls not just for your guitar, but also for the microphone channel. You can readily sculpt guitar tones while shaping mic EQs separately. Such a fine degree of control is bound to facilitate a professional sound once you’ve explored the simple, no-frills control panel that keeps setup and adjustments fast and efficient. Beyond the basics, you can add rich spatial dimensions using Reverb and Chorus. Plug in, dial in, and play with the kind of rich, real acoustic tone that makes for a memorable live performance.

Fishman Loudbox Micro Amp Features:

  • A robust, lightweight acoustic amplifier that weighs just over 9lbs
  • 40 watts of rich amplified tone that’s perfect for small rooms, busking, or rehearsals
  • 30 years of Fishman design and engineering give you revered acoustic-electric sound quality
  • 2 channels — 1 for your guitar and 1 for your microphone
  • All the controls you need — Phase, Gain, Low, Mid, High, Reverb, and Chorus for your guitar and Gain, Low, High, and Reverb for your microphone
  • Reverb and Chorus enhance performances with professional shine
  • Aux input for your smartphone and media players
  • XLR DI output for capturing your live performances

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Amazing little amp! You

I was looking for a small size practice amp for my new Taylor guitar, and decided to give this new Fishman Micro a try. Not too many reviews online since it's a fairly new product so I was a bit worried that it may not deliver a good sound for the size and money.

Boy was I wrong! this little amp sounds amazing, clear tones with a nice clean loud natural acoustic voice and without any distortion. The eq and effects are spot on and makes even beginner players sound amazing.

It's a perfect size for a small to mid size room (more than enough actually), and it's very portable and light weight.

Unless you're gigging professionally in large venues, this amp will give you more than enough power and satisfaction for your daily playing.

A big shout out to my sweetwater rep Brady Langefels, he was very friendly, professional, and I received great communication from him every step of the way.
Rated 5/5

Great Sound in a Small Package!

This amplifier fills the room with fantastic sound. It's the best amplified sound I've ever gotten from my electric acoustics. I have a 6 string Epiphone EJ200CE (which is 20 years old) and a Washburn Comfort 12-String which is 1 year old. They both sound fantastic through this little amp. The controls are user friendly and it will be my gigging amp for all our small clubs / bars. Cannot recommend this amp more.
As usual, Nolan Dye my gear guy, did a phenomenal job making sure I got my order correctly / quickly and easily. Sweetwater is my only source for gear for our acoustic duo and the full 4-piece electric band.
Music background: Gigging for over 25 years.
Rated 5/5

Great little amp. big sound

Since we plug into a board I have been looking for something besides my loudbox to take to gigs. So I got a mini and it works great. Then here comes the micro. I took it to a gig and our sound guy loved it. It is a great monitor and has the output for the board. I also took it to practice as a stand alone amp and the guys were stunned by the sound. Fishman should give me a comission. Every amp lugging one of them wants one !!
Rated 4/5

Fishman Micro

I just bout this item about 10 days ago. Only used in my personal studio of about 500 square feet. It fills the room nice and full without pegging the volume and drive knobs. The sound quality is signature Fishman, which always more than you expect out of an amp that size. I'd said say it is fine for instrument and mic in a studio size setting. It would be a bit light for restaurant gigs.
I like the light weight and easy storage. I only gave 4 stars because the control panel is tight and busy and oriented to read from the from the front but it is slanted toward the back so a little hard to figure out from behind or even from the front at first glance. Overall a decent value.
Music background: Advanced

My Fishman LOUDBOX Mini:::

I received the 1st one/ used it for about a week, then had issues with it NOT WORKING. I spoke with the appropriate people at Sweetwater:: and I was happy to have a brand new one sent to me/ at which point I would would return the defective one in the boxed one I received. There seemed to be some wiring issues with it & I am always pleased when defective equipment is replaced right away:: instead of returning it- to be looked at & possibly repaired. SW is tops in their field !
Music background: Guitar player originally at age 8 ! But took a long time off for my sport activities/ including trying out for the women’s Olympic Judo Team ! But:: have been back playing since high school on & off… but steadily since 1992 ! Acoustic/electric is my vibe

Want to make your guitar sound its best? Take it from the lifelong performers at Sweetwater and check out Fishman. If you've bought an acoustic-electric guitar, there's a good chance it came with Fishman electronics, but it's easy enough to upgrade your favorite instrument too - just ask the pros in Sweetwater's Guitar Repair Shop. Do you perform? Are you a singer/songwriter? We'd love to turn you on to Fishman's Loudbox amps and amazing pedals. But Fishman isn't limited to acoustic electronics. Many of us have tricked out our electric guitars with Fishman Fluence pickups and TriplePlay wireless MIDI systems too.
