In an attempt to make myself (somewhat) useful around here, I decided to make some comparison of the often-maligned stock Fender Marcus Miller Signature preamp. Attached are two somewhat poorly played but decently recorded clips of a little slap diddy played with the preamp on and then with it off. I think that the harshness that most people attribute to the bass gets lost in any kind of mix, even if it's some simple drums like I have. When the preamp is on, I have the bass and treble controls boosted halfway. I recorded Bass->Sansamp Bass Driver->M-Audio 410->Cubase. The Sansamp was activated, though I had the EQ flat and the Blend knob only halfway, with the Drive at less than 1/4. There's no compression on the track, as I wanted the somewhat natural compression of the preamp to be noticeable. Some of my hits in the E string might thwoomp a little but, but then again I'm not a slap player by nature. I'd suggest listening through some quality headphones or speakers as opposed to tinny laptop or computer speakers. Listening to the clips on my laptop, I'm hearing some distortion on the low notes that I'm not getting on my AKG headphones.
