Hey Bud,
I have this blues band, and we're gigging this summer. I am so much more comfortable with a P size neck, plus the joint at the base of my left hand thumb has an issue developing to increase the discomfort.I have played around and tried a P bass neck on the Jazzembic, and it allows me to dig in and be very clear too. My thoughts are to either sell the S1 or use the guts, OR have a new body built around the anniversary guts in the Jazzembic. You never heard it, it's a chambered mahogany body with a Flame koa top. I use and swr head w/410's and 115. I have read articles about s1 electronics versus signature, but I can tell you that the added volume in place of a pan has a major tonal change. I had another similar setup in a swamp ash body, but with a pan and it's night and day in the sound dept. Then there is the cost factors....show me a picture of yours please.
