In the following video, reviewer Justin Horenstein demos the Roland AC-40. This is a compact acoustic guitar amp that’s super lightweight at less than 12 lbs. It has dual 6.5 inch speakers for stereo and a tilt stand to angle the amp upwards. The amp has two channels, each with their own independent EQ, reverb, and chorus controls. Channel 1 has a dedicated GUITAR input, and Channel 2 has a MIC/LINE input for another acoustic guitar or mic for vocals.
The amp also has a master volume and anti-feedback switch that gets rid of unwanted noise. On the back panel, there’s a headphone jack, an AUX input to plug into a music player for jamming along, and a LINE OUT for plugging into larger PA systems. Finally, there’s a footswitch jack for using the Boss FS5U or FS6U to control the chorus and reverb.
