Hey, I just picked up a 2004-5 Fender Deluxe P Bass Special from somebody who knew less than me. No really. I usually play a MIM Precision, and I can understand the two knobs one for volume and one for tone. This Deluxe has 4. I would like to find out exactly what they all do, or are supposed to do. 1st Closest to the pickups appears to be the master volume? 2nd 3rd Inner and outer. Inner Treble and outer bass? 4th I have searched the Fender website for a manual, but everything id pretty generic and nothing really covered it. Any help would be greatly appreciated!
