Roland MOBILE AC Acoustic Guitar Combo Amp at a Glance:

Lush Stereo Sound from a tiny package

The Roland MOBILE AC may be diminutive, but its pair of 4-inch speakers pump out out a decidedly big sound. Kick in the onboard stereo chorus - an effect Roland put on the map with their JC-120 amp in the mid 1970s - and your guitar will be floating in a glorious, swirling soundscape. You also get reverb (with its own dedicated control knob), as well as the aptly-named Wide effect, for increasing the spaciousness of the sound. There's also a Tone knob that controls the overall EQ of your sound.

Built to Travel

Ultra-compact and lightweight, the MOBILE AC is perfect for travel. Just stuff it in your backpack, and you're good-to-go. Take it anywhere - a jam session at a friend's house, a picnic or camping trip, or even onstage to use as a personal monitor. It can run for up to 15 hours on six AA alkaline batteries, so you've got amazing freedom to perform anywhere you'd like. It even comes with a handy carrying strap. And if you'd like to run it on AC, there's an optional AC adapter. An optional carrying case is available as well.

Your new jam buddy

Invite some friends over, tune up your guitar, grab a mic - and you're ready to rock. The MOBILE AC sports guitar and microphone inputs with separate volume controls for each. Dial in a bit of tasty reverb, kick in the Wide effect, and you'll be sounding like a seasoned pro. You also get a third input - with its own volume control - for connecting your portable media player, letting you effortlessly juice your performances with backing tracks.

I've had this about 3 weeks and I just want to play with it all the time. It's friggin' awesome. Let's be frank - it's not a Marshall stack or a Twin but it makes my Taylor sing. The classic Roland chorus, adjustable reverb . . . I have been setting the volume a tad more than my unamplified sound. SWEET! I have "cranked" it a few times - sounds good. Not overly impressed with the microphone however I am using a high impedence Shure that is over 40 yrs old. I usually play about 2 hrs/day; now I have to make myself stop. For just sitting around and playing guitar I can't say enough good things about how wonderful this sounds. I've been using batteries but also got the AC adapter.
Music background: Playing over 50 yrs. Everything except Rap/Gangsta.

Small Amp with Huge Sound

I wanted a small amp that I could take anywhere with me that I could use batteries with but also had the option of a power cord. I wanted a rich sound not a cheap tin box sound. I talked with my Sweetwater Rep Devin Cunningham & he recommended the Roland Mobile AC amp. It is only 5 watts but it definitely sounds like more than that. It has reverb, jacks for your mic, guitar and a cd trainer or other device of your choosing. This amp is small and weighs under 6 pounds so I can conveniently take it outside to practice and on trips. You will not be disappointed in this amp if you are looking for a small amp with a great (huge) sound.

Really nice!

Really a nice little unit! Plenty of power for mild amplification to acoustic sound. Battery life seems good but I ordered the AC adaptor anyway.

Excellent Amp

For the small size and price range this amp far exceeded my expectations.

Jam Equalizer

I use my Mobile AC Acoustic Combo Amp as a monitor to enable my soft voice and acoustic guitar to be heard in a group of mostly electric instrument players. It seems to help them remember to back-off excessive amplified noise.
Music background: Still learning after retirement.
