Bass Preamps (Sansamp Bass Driver, B7K, Alpha Omega, etc)

[8stringalchemy]

I'd love to see some bass preamp builds. I've seen some schematics for the Bass Driver floating about there's no premade PCBs to be found anywhere and there's nothing for any of the Darkglass stuff.

 

[Andrion]

yes, please!
a simple update for Obisidius (b3k v2, with the tone knob) would be incredible too!

That must be an early Noble, the newer ones have the transformer and tubes both mounted inside the box. I have some gutshots around here somewhere from the one I took apart a couple years ago. They're very well-built, but I have a funny story about them when I get talking.

The Noble Preamp will be fine.
But. I think as long as this doesn't go any further, there will be time to talk.

Would be great to have Darkglass stuff

Would be cool to know what's under the hood of the EBS Black Haze, but even cooler to know what makes the Laney Black Country Customs Blackheath Bass Distortion tick tick tick tick tick tick tick BOOM!

sorry to necro an old thread, but i'd like to add the DG tone capsule preamp to the mix. there is a vero layout, and at least one other company has made it, but i'd love to see it here

Link to the layout and/or schematic?

If this it, I don't think it's doable:

Someone could cobble something together pretty easily using a few of my open source boards, although it's a little different topology from the quick and dirty test build I did a few years ago just going off the published EQ specs. But all my boards are at least part SMT, so a clean sheet through-hole layout would probably be a much better call.

Weird that they did a baxandall stack but fixed the treble, don't think I've ever seen that before.

i built 2 of them from PCBGM (and they actually worked ) and it's a super cool EQ. no shelving, all bell curves. bass preamps have ridiculously useless frequencies. super wide shelves at like 40hz and 10khz, bringing up TONS of useless frequency information. meanwhile darkglass said 80, 500, and 2.8k, that's useful, let's cut and boost there and nowhere else. and it's SO good.

Music6000 has raised a very good point in post #26...


Each circuit mentioned in this thread needs its own separate wish-list entry.

If a separate entry is created, I suggest this thread's corresponding missive-suggestion gets amended to include a link to the independent wish-list thread.

So, for instance, @maertz13 could edit post #25 to include a link to the corresponding wish-list thread.

This is exactly why I'm planning to do a complete overhaul of the electronics on my main bass that will include one of these, I feel the stock preamp has exactly that problem and it's extremely noisy in the treble to boot.

I did a pedal like that for a TB luthier friend not long ago, but then coupled it with one of my resonant LPFs for treble control. Works really well actually. Three knobs: Bass/Resonance/Frequency. It'll be a documented option when I get everything up on GitHub.

Very cool I keep forgetting to tell you, I have a bass preamp project in the works. It's still a secret, but I'll PM you about it
