Does anyone know if it is possible to wire a Cirrus (BXP, Indonesian) for a switch to choose between active and passive. Since this has active p'ups and an active pre, not sure if it's possible or not. It's a dead battery work-around in case they fail during a song, not a tone issue. It's a fear, it hasn't actually happened, and I change batteries every 6 months or so, but just in case... Thanks!
