Yesterday when I got my new cabinet, I checked it first with my HW1 Jazz Bass and then with the Warwick Thumb. The Jazz Bass has a nice warm, full sound when slapped and popped. The Warwick no matter what the EQ settings sounded thin and brittle in comparison. I like the Warwick's woody tone when playing fingerstyle but find myself liking the Jazz Bass as an all around good tone. What can I do to make the Thumb sound more like the Jazz? Change pickups or preamp? I really like the feel and looks of the Warwick.
