I got one of these in jr high to attempt to mix 4 mic signals down to a power amp (I didn't know the difference between mic pres and line amps LOL) and to try mixing DI isntruments to my stereo tape deck. It was the very early 90s. That's what we did untilwe could afford that tascan portastudio! I have fond memories of this guy and wish I knew where it got to. I probably gave it to someone. It was a bit noisey but warm and inviting and I used it to sum electronic instruments and computer stuff from fruity loops into a 4 and later 8 track (to save tracks, okay?! DAWs and multi channel soundcards were brand new as was USB) right up into the year 2000.
