My Reggie Hamilton Jazz bass MIM sounds great in active mode but sounds horrible in passive mode. The passive mode sounds unlike any passive bass I have ever owned. The output is extremely weak compared to my strait up passive P Bass. My questions are...does the active wiring installed have any effect on the passive tone when the in passive mode? Would putting "hotter" pickups in the bass result in an active tone that is distorted due to the "hottness" of the pickups? Any help would be much apprecated, electronics isn't my thing.
