I have a '03 Ken Smith BSR-5. I later sent it back to Ken Smith to have him ad the series/parallel switches. This is a really nice bass when it comes to recording. Live, sometimes it gets muddy. As of late, I've been playing it passive (vol. push/pull) through a Demeter stomp box preamp and it sounds killer live. The onboard preamps bass knob gets too blowded sounding when I ad bass. On the Demeter, I tightens up the low end when adding bass. I know Ken has a newer preamp that has dip switches etc,. A few years ago I put in some Bartolini's in a Fender Deluxe 5. 59j. with an Aguilar ob3 preamp. It just wouldn't cut through the mix. Finally I put in a Bartolini 3 Band Preamp and it sounded killer. Low Mids that would cut through any guitarist amp. My main bass is as an Fender Amer. Standard with Nordstrand NJ4SEs pickup. That sounds killer when I play through my Aguilar Tone Hammer preamp along with the Demeter and the MXR M-80. I guess not all pickups/onboard preamps are for everyones ears. Question: has anyone who's a Ken Smith owner put in another preamp in their bass? I debating if I sound try that or just do what I do with my Jazz bass and keep the Smith on passive and use a stomp box preamp.
