Boss AD-3 Acoustic Instrument Processor
The Boss AD-3 is a digital acoustic instrument processor, best suited for use with acoustic guitar. It has 1/4 inch connections and is powered by the 9 volt power supply that comes with it. It isn't a rack mountable unit as it is a stomp box.
Using the Boss AD-3 isn't a complicated process at all as it only took me a few minutes to understand exactly what everything does on this unit. The pedal has knobs for anti-feedback (with the ability to set the frequency), bottom and top (tone knobs), as well as chorus and reverb effects. The unit has two separate foot switches - one for anti-feeback and one for the chorus effect, both of which come in handy. The manual for the Boss AD-3 is pretty thorough and well put together, but isn't a necessary thing to have around as it is pretty easy to learn without it.
