BOSS Acoustic Singer Pro

The Acoustic Singer series of combos are designed primarily for singer-songwriters with guitar or other acoustic instruments, providing everything they need for a quality performance. Both channels feature three-band EQ, feedback protection and reverb. You can enhance your guitar sound with two types of chorus, vocals with delay and echo. An interesting twist is offered by the harmony function, which automatically creates vocal harmonies at the nearest appropriate interval based on chord/scale analysis of the guitar input - two types of harmony are available (upward and downward), plus a vocal doubling effect in unison. To make matters worse, the combo features a built-in looper with footswitch control and a USB interface for uploading to a computer. Two XLR connectors on the rear panel allow you to output each channel separately (before or after effects) or the entire mix.
