TS-9 rack 1U modification

[blackabate]

Hello from France

I transform my Ibanez TS-9 in a rack space 1U



How to select on and off ?
With my foot controler Berhinger FCB-1010...it's got 2 switch and I transform the wired of the TS-9 to accept a jack TRS mono controler


I play with my rythm patch (TS-9 off) when I want to play Solo patch (TS-9 on) there is no problem, all is running well
But when I return to my rythm patch, my TS-9 stay on, to turn it off I must select my solo patch again and then my TS-9 go off and then I can return to my rythm patch

So there is my question

How can I change the flip flop switch of the TS-9 to a flip switch ?

Thank you to read my mailthis post
