NONE!!!!!
I have the SD quarter pounder and stacked jazz. Neither is max, and the jazz is added in just enough to give the P thump a little snarl!
Hah! I had that EXACT set up in a Jazz Bass Special (think "Duff" bass), oh, about 20 years ago. I LOVED that combo! I no longer have the bass, but I have the record I played it on!
