In addition to the amazing digital effects, the A40 utilizes a DSP-based AUTOMATIC feedback elimination (AFB) filter. This digital processor
scans your input for any unwanted feedback, and will eliminate it. The A40’s 12 digital filters remove virtually any feedback from your signal
path! The AFB filter settings can be adjusted in any DSP program and will be applied to all program settings.
