what exactly was the mu-tron biphase? was it a real piece of audio gear? i was watching some video where they said they used it a lot. does anyone know what it did? and where i could buy one today?

I had one of those beasts complete with the pedal just like the link in that other post by aladinsane. I used it along with an Echoplex, a Big Muff, a Crybaby wah pedal, a Marshal 50 head with 2 SRO's, and a Fender Showman with 2 Altecs. Dust would rattle out of the rafters of our practice warehouse when I played (LOUD!) I finally gave it to Eddie Kirkland http://www.eddiekirkland.com/ about 20 years ago 'cause he likes lots of pedals and knobs and stuff. The newer phasers sound better with less hiss.
