It seems a company called Broughton (SP ?), makes these and they seem to be highly regarded here.
Are there other units I should consider?
Experiences with these and what is available would be some great information.
My rational for getting one is I often use a small setup with a single 2 x 10" cab and that cab does not have a ton of low end, but my style is not a "lots of low end" style anyway and I don't play five string.
Seems like a HPF would be a great addition to cut the stuff the cab is not producing at much volume anyway.
So what do you guys have, use, recommend?
I have a Broughton one and I am happy with it.
I think a high pass is great to deal with the mud of different live rooms. A really nice sounding room, I may use a pretty low setting, a bad one, I'll cut more.
But I in particular got the Broughton as I was running more synthy sounds through my bass amp and I in part was wanting to protect and get the most out of, like you, some 2x10s.
