what is your reason for using an onboard preamp

I am new to the onboard preamp world and am not really up on the usefulness of it.
I get when I sit in, open jams.. nice to have control over the tone, but when I'm playing with my gear I get a sound and thats that.. stay passive. NO need for preamp into preamp..

How do you all use them?

I have an active bass. 99%of the time, it’s being fed into the FOH, therefore I keep it at flat. I very rarely use the ability to boost low end or treble. The bass sounds great as it is, and I don’t want to cause problems with the sound engineer.
 
Onboard preamp is my first choice for tonal variations.
My basses have a pre without center detents and I'm used to shape my sound with this preamp (using amp for room adjustment). Plus it sounds great plugged straight into a mixer.
The other one have center detents and it stays flat most of time, but just beacuse it have some internal dip-switches for shaping the sound in 4 different ways...

One thing about onboard preamps is (I think) they act as a buffer, which should prevent interferences and signal degradation (but since I do know nothing about technical stuff, wait for someone who knows what is talking about on this subject ^^ )

I hate not having center detents on EQ knobs.

I like to be able to tweak from my bass, so having active EQ on my bass is a nice option to have.

As for preamp into preamp... why not? Every preamp may give you different tonal characteristics and you may prefer X from one and Y from another.
In most places I play I have my bass DI'd and my amp onstage is really just my monitor. I use the onboard preamp to adjust for the sound I want (and I do change it slightly during a set... some songs I want a more prominent mids-rich sound, others I stand back a bit) and adjust the amp controls simply for the sound onstage, which is not necessarily the prettiest, but the one that allows myself to... erm... monitor best what I'm doing.
 
Active basses, as well as pedalboard preamps, allow the player to make adjustments to the FOH tone. Unless you’re running a DI post-preamp, settings on the amp are simply changes to one’s stage monitor. It’s nice to be able to scoop the mids, boost the bass or add some edge when needed for a particular song.
This is an important consideration. If I care about my sound (I do) then I want to make sure it is delivered to FOH. My amp has nothing to do with that (in fact I don't even bother with an amp unless I have no alternative). What I am delivering to FOH is what comes out of my bass. So the more control I have at the bass the better.

I do need one more knob though - one that controls the guy running FOH, some kind of bypass that takes his fiddling out of the loop.
 
Because of this beautiful beast. Its so much advanced towards a passiv Bass. The sound possibilities are mind blowing and the tonal and overall quality sets a new benchmark in the music world.
Thank you Markus Miller for making it happen.

I have one active bass and it actually has two built in preamps one for each half of the 4 coil humbucker pickup gives me almost limitless tonal options, but I mostly use it in what I call Pbass mode but I can get Jbass-ish and full on vintage Music Man vibe too. I mainly use it when I’m having to use someone else’s amp so I don’t have to mess with how they have it set. My 36 year old Peavey T45 passive is my usual go-to, it will do a lot passively what my active does.
I would love to see a picture of this ethereal instrument! You must of messed with those knobs for a long time before figuring it all out. Thanks for your comment.
 
The preamp on my US Peavey Cirrus sounds so good, that I use no external eq/amplification. The sweepable mids do it for me, both live and in the studio, with the same signal path...Zoom MS60B, Markbass Mini Boost (slap contour), and then into a Radial DI out to the board. A T-Rex battery supply powers everything. Technology can be wonderful.
 
I found this thread during a search for something else and reading it, I came across this, and had to add my 2c worth.
Some pickups require them, i.e. active EMGs and Barts. The inherent nature of those pickups that have such hi-fidelity have a low output and need the preamp.
Simply not true at all. If anything the lower output impedance of an active pickup means it is less likely to need a preamp as the internal amplifier buffers the pickup coil from the loading that it would get from passive controls, so it is more consistent tonally. It should in fact be entirely independent of any subsequent passive VVT etc controls in circuit. The lower output impedance of an active pickup means it will drive the capacitance of cable better and the often too low input impedance of some pedals.

As for output levels, my EMGs are some of the highest output pickups I've ever used. We'll see how the SD ASB2-5s are when they arrive, but I suspect they'll be little different.

Just to clarify, I am only discussing active pickups here, ie those like an EMG with a preamp/buffer inside the pickup housing.
