Pioneer DJM-600. Zoom these photos and compare.

I purchased this new, used it briefly, but never traveled with it.  Like almost all my now-unused gear, it has sat under plastic for at least a decade.  Superstar-Dj dreams have morphed into beat-making-hobbyist/dad-life.  So after recent inspection the only thing that isn’t perfect on this unit is channel 4’s line/phono switch.  It works and feels solid but if jiggled, can make static sound and sometimes cancel sound on right side(or left, I forget).  A fixable issue.  Unit has noticeably very, very little wear as it was used gently and briefly.  Please observe the photos above.  Crossfader is practically mint as I didn’t use it much at all, if that matters.   This became simply a utility mixer to get sound to my speakers for my drum machine, synth, Kaoss pad, etc in my home.   No smoke, drink, or club/party-environment came near this unit ever.   Kinda sad about that, actually.
