I have an old Ibanez 707 with a PJ setup. The P is a Quarter Pound Duncan, the J is out of a Squire. First of all, would the P alone, put out more than if I add the J? The trouble is, I also play a passive Stingray with a Duncan MM pickup. When I switch basses in a live setting, the MM is super hot compared to the Ibanez. Id like to bring the Ibanez up. Would using just the P help?
