Roland AC-33... JUST BUY IT!

Yup Blown away. Just buy this little monster. If you are an acoustic player, weather playing at home for fun, or out gigging, this is the perfect amp. Light weight, battery operated if desired can't even get my point across as to the value of this amp. All I can say is buy it. Sweetwater (needless to say) is a great company and I only do business with them. Patrick is the KING!

BUY IT NOW

it's fairly simple, if you have an electric acoustic guitar, and you want to amplify it... buy this little gem of an amp. Everything that has been written about it is an understatement. This thing just blew me away. super light, batteries don't cut down the power as much as it indicates, and it just immediately inspired me to make new beautiful music. Way to go Roland and of course to Sweetwater for offering it. AAAAAAA+++++++++ all the way

The Roland AC-33 has got to be the Best in it's Class!!!

WOW, I am blown away by Roland (Once Again) and the superb service from my Sweetwater sales engineer, Jorge Padilla! I have always been a fan of Roland and have purchased many of there products over the years and it looks like there will be many more years to come. The Roland AC-33 is an amazing little (30 watt on AC / 20 watt on Battery 8AA) portable acoustic guitar & vocal amp that has to be the best in its class for every guitarist/keyboard/entertainer/vocalist. The tone, effects, inputs, outputs, size and light weight make it a favorite for me. I've own the original Roland Street Cube for some time now but I will now prefer using the Roland AC-33 over it because it will meet my needs more in acoustic guitar playing and singing. I have tested this little amp with an Acoustic and a Electric guitar and both come across with a warm clean tone that might also suite a jazz guitarist, if interested. I watched all video's on YouTube on this amp and needed to know if the line outputs (L/R) would run to an external powered speaker without canceling the main speakers on the amp. I never saw one but was pleasantly surprised at how both can work simultaneously with each other together. Yes, the feed gets sent completely to the other speaker and now I can use the amp as my monitor and the output powered speaker as my main cabinet if I need to do a bigger functions. (Note: Using the headphone out the on the AC-33 will cancel out the main speaker but this is ideal for practicing without disturbing others) You can also use the mini jacks and RCA's on the back, at the same time too....I have my keyboard plugged into one and my iPad backing tracks in the other while playing guitar and singing through the other two main input channels....Very Very Clean and Very Very Cool! Later on I will go with a little mixer plugged into the RCA's and just run all my other stuff through that instead and get a better EQ on the keyboard & backing tracks. The possibilities are endless and by using your imagination you can find the right set up for this baby and do many kinds of gigs. I Love It and Thank You again Jorge Padilla at Sweetwater for all your help in getting this to me as fast as you did. It only took 2 days to Bermuda after the sale went through...Amazing!!! I'll be back soon for a few more goodies and the catalog and candies in the box was a nice treat to send with my purchase. It was wonderful dealing with you and thanks again....Kevin Ingham

Finally!

For a few years I have been using a Boomerang Looper during performance to enhance the depth of the show. I perform Rumba Guitar - much like the Gipsy Kings - and the music needs backup guitars.I owned a Crate Limo for my battery powered amp, and although the very functional, the tone was always so bad with my Flamenco guitars. Goodbye bad tone, hello Roland AC-33!Finally, Roland was smart enough to produce a battery powered ACOUSTIC amp with a BUILT IN LOOPER! This amp sounds lush, weighs in at a bit over 10 lbs, and with the extra FS-6 pedal, it is a one handed load in. Couldn't be happier.The only con I see so far is that it takes 8 AA batteries to go mobile. I bought rechargeable's, so no problem there.Of course Sweetwater has the best service on the planet, so any issues, just give them a call and it is done. A no brainer if you are a busker or need amplification for gigs without power.

SO MUCH FUN

OK FOR WHAT IT IS IT IS JUST DYNOMITE. I HAVE LOTS OF AMPS. MESA BOOGIE'S , GIBSON SUPER GOLD TONE, FENDER DELUX REVERB LTD EDITION, PEAVEY DELTA BLUES, LARGER ROLAND 60. AND MORE BUT I WANTED SOMETHING I COULD TAKE OUT TO CAMP WHERE MOST PLACES THERE ARE NO ELECTRICAL PLUG IN'S. SO I TOOK MY LITTLE ED SHERRAN TRAVELER GUITAR MADE BY MARTIN AND THIS LITTLE BATTERY POWERED JEWEL AND MY MICROPHONE TO YOUR HUNTING CAMP ON THE RIVER. OUR HUNTING CAMP IS FOR OUR CHURCH MEMBERS. WELL I JUST GOT TO TELL YOU WE HAD AN ABSOLUTE BLAST. NO WERE NEAR A PLUG IN WE PLAYED AND SANG OUR HEARTS OUT. THIS LITTLE AMP SOUNDS SO GOOD AND THE EQ'S ON IT MAKE THE LITTLE GUITAR SOUND FABULOUS. SO FOR WHAT IT IS MADE FOR I WOULD GIVE IT 10 STARS.
