I have a Korg Pitchblack Pro PB 05 Rackmount Tuner that has only been used a couple of times and is a very cool and accurate tuner to have in a rack if that's your thing. It picks up the "Low B" with nary a problem. I'm looking for a decent tuner pedal, or an MXR M87 or Markbass Compressore if anyone would has one to get rid of and in need of a very decent rackmount tuner. Original box and paperwork included. All replies or PM's are welcomed.
