Hi there!!!
Just a question for you... If these red wires (I have already wired them following your advice) are not wired means that the pickups can work as actives or passives? AFAIK an active pickup needs a battery for its pre-amp. If not attached, the pickup would be "in passive mode", isn't it?
Working in that mode, a good mod should be adding an on/off switch for pickups/EQ. What do you think?
Thanks.
