Vintage Guitar is marking 25 years of publication with a year full of features. This month, using data compiled for The Official Vintage Guitar Price Guide 2011, we continue the celebration with a list of the 25 most valuable effects.
11. 1974-’77 Mu-Tron Bi-Phase (with optical pedal)
($1,000 to $1,250)
This variable-resistor-based phaser offered extensive control functions, and yielded a deep, lush tone. Whether used on automatic or controlled manually via an external optical pedal, its dual sections (A and B) could be set independently or blended to create a tone few phasers have approached since.
12. ’77 Mu-Tron Flanger
($1,000 to $1,250)
Another great, spacey effect from a company whose quality seemed a cut above so many pedal makers. And what happened to Mu-Tron? The company died a slow, agonizing death in its efforts to market the Gizmotron automated guitar “bowing” device, invented by Lol Creme and Kevin Godley of 10cc. I’m not in love…
