High Pass Filter

Who uses it/who doesn't?

What are the technical pros/cons of it?

I'm running an SWR Marcus Miller preamp into an Ashdown ABM810

Apparently its a pretty steep filter, and lowest freq is 50Hz.

Might not be too noticeable on a 4 string, but I bet you'd notice a 24db/octave cut at 50Hz on a 5 string that goes down to something like 27Hz, almost an octave from the HPF cutoff at 50hz.

I was excited about it, until I saw the cutoff freq. Its made to be a cutoff if you're using a subwoofer. Not as a subsonic filter.

I just picked up that amp, read the manual but haven't actually tried it yet.

Wouldn't hurt anything to try it if you want. I love a subsonic filter, seems to eliminate a lot of cone motion that I always assumed was the bass, but turns out were subsonics generated by string handling/etc. I have subsonic filter in my effects loop @ 20Hz now.

I have tried it with a 4-string and a 210 cab... IMO it is too high to be useable. if it was at 30hz I'd use it all the time.

Hey Steve, Suggest me a subsonic filter I could try in my effects loop?
Wouldn't mind having something around 30Hz on my rig!

most cabs start to roll off at +/-40hz anyways so there really isn't any need for anything below 30hz anyways IMO
