BOSS KM-60 – 6-channel vintage mixer SN 985423

via this auction
"This is a very rare and cool looking 6-channel vintage mixer (build in the late 70’s in Japan) with level, treble, bass, effect level, pan and 3-stage input attenuator per channel. In the master section you will find the master and the effect return controls for the left and right channels. Also the monitor output control, the switch for low cut filter on/off and power on/off and, not to forget, these two coll looking backlid VU-meters are there. It is build like a tank as many gear off these old times.

The size is 19" x 3,7" x 10,8" and has a weight of aprox. 4,7kg.

I used it a lot for summing drum machines, samplers and synths with the benefit to overdrive it, to get the warm characteristics and distortion out of this wonderful piece of gear..."


  1. i just got an old one of these. only problem is the on off switch is missing.
    i opened it up to have a look and see if i could bypass the switch, but its not like an ordinary switch. any ideas for a replacement, or another way i can bypass it?

  2. I have this same issue any ideas?? would be greatly appreciated. Thanks.!
