Bass preamp

[Domin]

Hi! Im going little bit into Justin Chancellor tone and i would like to make clean bass preamp which i can mix with my dirty tone. After bass im using state variable filter preamp in a box and after that for just little bit of dirt proco rat and i want to mix that proco rat with clean signal but adjust it to taste with eq. What about alembic f2b? My proco rat and my amp(just Ambeg BA108 v2 for practice) would be one channel and second would be that preamp blended into my ampeg

On the other forum there is a big thread about the Orange Bass Butler - PCB designs are available.  One of the forum members also was selling the PCB.  It's not about mixing what you already have with clean, but it already has the dirt and clean in parallel that you can mix.  Also can switch dirt on/off at will.
