Hi all....i want to make a A/B box for my rig ...i'm already using a LS2 for looping some of my pedals and i think a second one would be overkill for what i want....my amps don't have any effects loops and i want to keep my dynacord unit out of my signal chain when not in use but keep it's stereo effect..my amps have two inputs on each channel like all the old amps do so i was gonna plug the unit into the spare channel on each amp and run a lead from an A/B box from the floor so i can 'bypass' it when i don't need it....so the question is ..how hard is it to make one of these devices....?? thanks....
