Up for sale is an ultra-clean, collector-grade Boss KM-6A 6-Channel Stereo Utility Mixer, manufactured in Japan by Roland. This is easily one of the cleanest examples on the market, complete with its original factory box.

​Fully tested, serviced, and 100% operational. The illuminated VU meters react cleanly, the red power indicator shines bright, and all potentiometers and switches actuate smoothly with zero scratchiness or signal dropout.

​These vintage KM series mixers have become legendary secret weapons for electronic music producers, lo-fi beatmakers, and recording engineers. Known for their discrete preamps and harmonic analog summing, pushing the channel inputs into the red delivers a rich, musical saturation and warm distortion that plugins simply cannot replicate.
