Rectoverb series 1 footswitch..any way to mod the cable??

[crowguitar]

Looking to mod the cable to work with my Lexicon Midi footswitch. It can control an amps functions thru A/B controls, but the series 1 Rectoverb uses that multi-pin cable thats permanently attached to the actual footswitch. Does anyone know how to mod a cable to go from the pin jack into separate split 1/4" jacks? Is that even possible and does anyone know the pin configuration to achieve this??

Any help would be greatly appreciated. Long time Mesa user...Pro session & touring musician lookin for help..

Thanks in advance,
Sincerely,
