■ The AC-33 is a compact amplifier designed specifically for acoustic guitar. Its 30W (15W + 15W) stereo output with two custom 5-inch speakers delivers a rich sound beyond its class. The lightweight and compact design of the unit makes it highly portable, allowing you to move it around the house or even take it outdoors. It also features a tilting stand that allows you to adjust the angle for easier monitoring when placed on the floor, allowing you to monitor in the optimal listening position.
■ Dual power supply: AC adapter or AA batteries. This battery-powered amp offers the convenience of a dedicated acoustic guitar amplifier. The removable battery case provides up to 8 hours of operation with eight alkaline batteries, or up to 9 hours with nickel-metal hydride rechargeable batteries. It can also be used in street or outdoor situations where securing a power source is difficult.
■ Two-channel design with a mic/line input in addition to the guitar channel. This allows you to input microphones and various other instruments, making it versatile for a wide range of applications. The mic/line input accepts three types of plugs: XLR, standard, and TRS. Since it's completely independent from the guitar channel, you can connect a microphone and combine guitar with vocals or acoustic instruments using just the AC-33. You can also connect a guitar with a built-in preamp to the standard/TRS jack, allowing for duo performances with two guitars. There's also a separate AUX input for connecting a CD player or portable music player. You can mix the sound from the guitar channel with the mic/line channel, allowing you to play along with songs.
