This amp was made to go places no amp has gone before. Thanks to its battery-power capability, the AC-33 lets you take your act anywhere - into the backwoods, onto the streets, or wherever your imagination leads you. 

Rosewood Finish!


Now the AC-33 is available with beautiful rosewood-look cabinets, offering an alternative to the standard stage-ready black finish. The attractive woodgrain styling perfectly matches the atmosphere of your living room or studio, as well as the aesthetic of your acoustic guitars.

Natural, Stereo Sound


Equipped with Roland's latest DSP technology, the AC-33, delivers pure, rich acoustic sound with projection far beyond its size. Its true stereo design (15 watts x 2) enables brilliant stereo/multi-band chorus with "Wide" mode, plus shimmering reverb and 3D-type ambience effects tailored specifically for acoustic guitar.

Strum and Sing


The AC-33 provides two discrete channels: Guitar and Mic/Line. Plug in an acoustic guitar and a microphone (or line-level instrument) and mix them separately. Both channels have dedicated controls for volume, multi-band EQ, and chorus. The Mic/line channel offers both XLR and 1/4" inputs. You can also connect an MP3/CD player to the stereo AUX input for play-along practice or performance. Master volume, reverb, ambience, and anti-feedback are provided as well.

Phrase Looper


This amp was made to go places no amp has gone before. Thanks to its battery-power capability, the AC-33 lets you take your act anywhere - into the backwoods, onto the streets, or wherever your imagination leads you.


The AC-33's onboard Phrase Looper lets you record, loop, and jam over your own guitar riffs or incoming audio from the AUX input. Record and loop up to 40 seconds at a time, and amaze your listeners with sound-on-sound performances that you create on the spot.

We Welcome Part Exchange

We welcome part exchanges on items over £500. We realise that sometimes you need to “move something on” to get your new guitar. We give fair prices and once agreed we stick to them. The only thing we ask is that you accurately describe your guitar. We have plenty of happy customers from our part exchange scheme.

How it works – If you are local, you can simply call in. If you are not local we will assess your guitar and give you a valuation via phone/e-mail (we may ask for pictures). Once the price is agreed, we always stick to it, and your new guitar will be removed from the market so the deal can be concluded.

You can either send us your guitar, or we can use our courier to pick up for a small charge (UK only). Once the guitar is with us and any balance is paid we can dispatch your new guitar.
