Tried one of these today. On the search for a P/J, this one seems to have all the goods, and part of the appeal is the active/passive switch. Loved the tones and feel of the bass. Now I have a question, tried to search the fender site, but the schematics show older american deluxes (with the bucker, and I believe no A/P switch) Do you know if the switch bypasses the preamp completely when in passive mode ? Or to put it differently, will the passive controls (tone control, the individual pup volume controls and the pan pot ) work with a drained battery or no battery at all ? Thanks.
