WM-1 WAH MASTER

Effect Information

“Made between 1968 and 1972 by Ace Electronics
Industries Inc.
which was part of the the Sakata Shokai Limited of Osaka
Japan. The Ace Tone effects line was the predecessor to Roland and Boss.
It is very well made and solid. The foot pedal is spring loaded so when
the effect is on it won’t activate unless your foot is on it. When the
effect is off you can use the pedal like a on/off toggle switch to get
some tremolo or Ace Frehley style sounds.”
