This is a vintage DF-2 distortion pedal by Boss, made in Japan in 1985. It is fully functionnal, in great condition and comes with the original box (see pictures). It has the usual level, tone and distortion adjustment knobs, and also features an overtone adjustment knob to control the amount of feedback you want. Also, if you keep the footswitch depressed, it will give you endless sustain (i.e. the note you're playing will ring as long as you keep your foot down). I'm not interested in trades. THIS IS A GREAT SOUNDING PEDAL IN LIKE NEW CONDITION!
