This is a good shout: you can pretty easily replicate the suggestion provided for how to do this with the 4 On The Floor (HPF/LPF/blend) and it’s a lot smaller.The Source Audio Aftershock is a simpler dirt pedal that's got overdrive really well covered.
I woud choose one of the Muff engines and change the treble and bass options to suit.
The Bass overdrive engine is pretty dynamic and versatile too, one of the best Bass overdrives I've ever used - period.
There’s the other advantage that you have the choice between the Aftershock, LA Lady, and the Kingmaker (they’re all the same pedal) to find the best deal.
