High Pass Filter (HPF) and Low Pass Filter (LPF) Mega Thread

2 in series won't work as intended, the frequency and slope will not add as expected because the filter expects a low source impedance. Passive filters are tricky like this.
Yep. The difference between putting them in front of the preamp and in the effects loop bears this out. One in the Effects loop seems to be the sweet spot so far for me. I can go two but have to compensate a bit with the bass level a bit so I assume the cutoff freq is moving up. In front of the preamp you see a noticeable level loss using both.
 
So after having my Broughton for a few weeks and a few rehearsals into it, I can say that I should have bought one of these gizmos years ago! So happy to have eliminated most if not all the bloom inherent in my sound and as a bonus, to me anyway, I have noticed a significant increase in growl in my basses tone.
I am assuming that it has always been there, just being masked by the overwhelming bloom.
Happy camper here...

Your speakers will appreciate not having to bare the load of ultra-low frequencies that only whales could truly appreciate in the first place. :D
 
Sorry To ask, maybe already asked but not enough strong to read the 74 pages ... ( usually I am enjoying reading long threads)

DO high pass and low pass filters with resonnant peaks exist on the market in pedal format ?
I guess something like filter based preamp indeed ...
Why specificly do you want resonant peaks?

Some wah-wah pedal variations do that. They can do frequency notches, some do peaks, that is are shiftable bandpass. Rocking the pedal shifts the frequency. Some use it by leaving the pedal in a fixed position.

Read the paragraph near the top, “What a wah does is clear.....”

There was a post in the Broughton thread from someone who ordered a custom LPF with adjustable boost at the filter cutoff frequency, like Alembic onboard filters. There is also Iron Ether Xerograph (the non-deluxe version without envelope follower) which has a resonance control. Probably others as well.

Quite a few people have built my open source resonant LPF into stompboxes. You can find all the details in the TB Wiki section and the Electronics/Pickups forum thread.

It will also increase usable headroom in nearly any amp - it really makes a big difference with my Rumble 200 Combo...

The rumor mills have said that Broughton will be releasing one. All I can say is, if you're planning on getting in the queue for one, be prepared to have your 'dreams crushed.'

Yes Thanks it is the same effet.
But in a wah pedal the amont of boost at the peak is fixed

Why ?

There are many speciality variations and wah mods available. It’s just a matter of finding the right one that does what you require. I would be surprised if you couldn’t find an analog one with variable peak boost.

Then there are digital oneso consider. See if this one does what you need.

Also, see what the Eventide H9 can do.

Uhm,

I'm not sure if whales would really appreciate it to listen to transient noise (subharmonic) content.
The term subharmonics is very misleading the point anyway cause transient noise is NOT composed by harmonics.

I think the point @Fishheadjoe wants to tell us is the benefical improvement of sound quality if a HPF filters the sub transient noise content which may make a sound unpleasant.
Sometimes I think guitar players should also use a HPF. Lots of guitar players like it to "enrich" the sound with lots of bass boost content. Interestingly its the generated transient noise at the lowish side of the bandwidh rather than total harmonics which may make a 6-string sound unpleasant.

edit, same consideration is valid for keys as well.
