Hi I´m getting near the end of building a jazz. When test playing I started to wondering bout why there´s no 3 pickup in the neck position. So I made a simple set up with an old extra jazz pickup, sliding it up and down the body to se what would happend. My goal was to achive a bit more deep sound. It turned out that it did add something extra but it seem to be very hard to find the exact best position, one mm to the left or right change the sound. Sliding it very much together with the bridge pu created a flanging sound! I guess that would be the resonas frequensy changing? So my question is. Has anybody else tried this? Any result to or idees to share?
