That’s the other popular option where to put a HPF. Sort-of for speaker protection / don’t let the speakers work overtime trying to produce frequencies too low to be usable. Or to clean up stuff should one use a pedal which introduces loads of subharmonic content; so you tend to put it towards the very end of your signal chain and probably set a lot lower than some dial in their “in front of everything” HPFs.
I guess most people who got a Broughton RFE or the combined HPF/LPF pedal would also steer towards this option. Having the LPF at the end is nice for simulating tweeter-less output when going direct, rather than sending a full-range signal, so you’d put it just in front of the DI out, and that’s where the HPF will end up, too.
As always, one should experiment with pedal order anyways. I run my compressor as the last pedal in my chain, for example, while most would probably put it first after the tuner and/or envelope filter. But I like how dynamic both the MBD2 and preamp react to my uncompressed signal, so there’s that.
