There is a lot to say about the effects of different preamps. To an extent, the amount of electronic processing we go through to produce a sound makes them a bit less releveant, from preamp to preamp- unless you're super fussy and can have consistency.
My first 6 string was a Gio 206b with a 2 band preamp which I picked up for $100 (including deluxe case). I had a $10 Chinese preamp in my bin that I hadn't used on a previous fix-up job. After the installation, the sound was really really good. BTW... You would think that the "before" photo showed a USED bass. NO. It was a NEW *DEMO* that was BTS. The finish on some SR's are so thin that a fingernail scratching it could get down to raw wood. But you can see the extra knob on the "after" image. No one would know it didn't come that way. $10.
