broughton hi pass filter pedal

[overdrivenel34s]

Not long ago, i got a broughton hi pass filter pedal. It's quite useful utility pedal on my practice pedalboard used with backline amps such at rehearsal studios and gigs with backline. Some amp's and or the cab's bass response can have unwanted sub-lows boomy response that sometimes can be hard to dial out to where you may just tradeoff to dial backs low eq way back or just deal with tone thats a little too boomy.

Some drive pedals can help(ie sd 1 cuts lows) but then kick it off and its too much boomy low end. This hi pass pedal allows tightening low end with rig overall so easily (one knob) as always on without making low end thin and then its also seems like other pedals on board sound better with the amp. Of course it can be bypassed if not needed with particular rig and its small pedal that doesn't take up much room. At gigs, on pa mixer there is hi pass filters applied on guitar channels to help sit in the mix too but this pedal on board helps with on stage sound.

I swear by high and low filters. Having a high pass before lots of gain helps the feel of the amp (or distortion pedal). Having a low pass in the loop (or after distortion pedal) will tame the fizzy high end frequencies. I've made some simple passive filters to shape some rigs that I would not want to use.

Any chance you could share the guts of the Broughton?

Amazing! And here I am thinking high and low pass filters were only for recording and microphones!

Hmm, i guess i could try opening it up and taking pics. Right now its packed away in pedalboard. This is what the pedal itself looks like.

One of my amps has one built in. Some power amps have them built in to , some may surprise you it has one so check the specs. I also have a pedal sized one I use sometimes. With a bass rig it can solve a few things. One of those things it solves is power robbing. An amp is usually pushing lows as far as it can go down to 20 Hz or beyond. This takes all the power from the amp. It can also damage speakers from over excursion. This pushes the driver past its limits and usually puts a crease around the cones or destroys the cone and coils altogether. So controlling all that energy by rolling it off is a simple solution. This is pretty standard practice in recording as well it greatly effects how your compression responds and the overall all mix. You don’t need all that energy down there where it’s not being heard.

Interesting. I can see this being useful for sure. I have HPF on all my guitar channels when recording. Never thought about doing it in my rig. I have to check one out.
