Hi all. I play bass, live in SoCal, and hope to add to the knowledge here since I recently upgraded my Yamaha TRBX174 with a SD Hot Jazz Stack Pickup. The original J pickup sounded very good, but was noisy in the studio and on stage. I will write up my review in The Pickups And Electronics section of the General Forum here. My first Bass, a Dan Armstrong clear acrylic was stolen off stage, so I picked up a 1972 P Bass that I used for a very long time. My current bass is my favorite, a Yamaha TRBX 304 with dual Music Man style humbuckers with 5 way EQ switch. Very versatile with great tone. Jefro.
