Speaking of squelchy funk, if you’re looking for the quintessential 70s space-funk bass tone, the EH Q-Tron is probably (besides the Mu-Tron III if you can still find one these days) the best in the business. The sheer tweakability of this pedal makes it incredibly vertsatile, and the Q-Tron+ has the added bonus of an internal effects loop, which lets you plug other pedals in between its filter stages. Stick a fuzz pedal in there to create your own Frankenstein funk sound.
