Ok so I took this thing to rehearsal last night to run the Zep. show. This bass is a whole different animal compared to the American Standard Jazz. The overall tone is warm and woody with less focus than I am used to in a J which I like. Not the usual "brittle" tone I associate with Jazz basses. The upper register is very lively notes just sing, the G string in particular. I gave the bas a quick set up when I got it and put on a set of old Rotosound RS 66LDs. I ran the neck pup only and was able to get full round tones for Dazed and Confused to a sharper more treble tone for Houses of the Holy. I used my Seymour Duncan Pickup Booster to give the pups more output, all in all the bass performed just as I had hoped.
