But 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.

New 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.
