The now-discontinued BOSS AD-5 Acoustic Instrument Processor offers everything an electric acoustic guitar and bass player needs to produce a rich and complete acoustic sound in the studio or via an amplifier or PA system.
Many players still use the AD-5 as it has a very warm sound with an acoustic guitar.
Includes 2 inputs for magnetic and piezo pickups, stereo line out, body and mic distance controls, chorus and reverb, and perhaps the best thing of all, a very handy Anti-Feedback control that tames hecklers in your audience. In good condition and runs from a 9V DC adaptor (not included but we have them for sale).
