Lowrider 2015: switched outputs Mod

[cewren]

So here's the idea
I want to be able to separate the octave down from the dry and the octave up, via a switch
so im thinking leave the high and dry as it is
and insert a switch between R33 and Pin 2 of IC1 which would switch between pin 2 of IC1 and a seperate final amp stage (which op amp would you recommend?) sending the low and sub to a separate output so i can send it to a seprate bass amp, and play with two amps because im bad ass

Thoughts...
