A.The AC-3 has the following features that are not found on the AC-2.
- COSM Effects Processor
The AC-3 uses BOSS's proprietary COSM acoustic modeling technology to simulate the sound of an acoustic guitar from an electric guitar input. This is the same technology used in the acclaimed AC-8, the flagship model of the AC-series.
- LINE OUT jack
The LINE OUT signal preserves the high-frequency range that is such an important aspect of the distinctively rich sound of an acoustic guitar. Use this jack to connect the AC-3 to a PA or other speaker system with a flat response up through the high-frequency range. Additionally, you should use LINE OUT when recording the output of the AC-3 directly into a recorder (such as a BOSS BR-series unit).
- Reverb
A high-quality reverb designed exclusively for use with acoustic guitar sounds is provided.
