Check out Zorg Effects Glorious Basstar. They offer pedal or kit. I haven’t built the kit, but it’s a cool concept. Split the signal into 3 bands, then control gain and volume separately for each band. This allows, for example, clean lows with driven mids and highs, or whatever combination you want.
Edit: I just re-read your original post, this isn’t what you’re looking for. Still a cool pedal to be aware of I think
