Ibanez - STEREO BOH

"MB: WOW!!! BOH??? RM: BOX MB: BOH - it's a micr font!! RM: yeah but that’s not what it’s called."

"it is a tremolo (stereo alternating left right) speed adjustable for two amps or effects ... mono = tremolo; Stereo =panner ... What does the Stereo Box do? Well, not very much, but what it does, it does very effectively. Connected to two amps it pans the signal from left to right and vv. Connected monaural just to one amp the pedal delivers a dramatic tremolo effect."

neither the example nor this one (legionfonts.com/fonts/micr-regular-db) match exactly, though.
