I have an Ampeg Pf350, so I don’t believe that has a hpf. I also have a muting tuner already (Korg Pitchblack). I like the look of separate pedals, and you can swap them around, and as everyone keeps saying about heads & cabs vs combos, if one dies it doesn’t take the other with it.
The other thing putting me off the one pedal solution is some of the other Zoom threads here - do you have to run 2 hpf’s in series to get a decent amount of sub cut on the B1-4?
I think i’m just convincing myself to get the separate bits!
