The OD-20 Drive Zone uses advanced COSM technology to model the sound of classic overdrive/distortion pedals, as well as creating new sounds of its own. There are 22 models to choose from, plus new "Attack Shape" and "Heavy Octave" parameters for dialing in subtle nuances or extreme tones. You can even switch amp channels remotely using the OD-20's Amp Control jack. Now discontinued (boss.info).
Second-hand, in good condition, some cosmetic wear as shown in photos.
