HPF/LPF list- which do you use or know about?

#83
The Crown XLS1002 has an adjustable DSP-based HPF & LPF. $300 new. Oh yah!, did I mention there's a 1100 Watt @ 4 ohm (bridged) power amp attached? :woot:

Drive it with your choice of pedal-board-or-rack pre-amp and FX chain. It has selectable, pedal-or-rack-friendly input sensitivity. :)

I feed the Crown with either a Mesa Subway Preamp DI, MXR M81 Bass Preamp, a homemade B-15 tube style preamp, or the sublime Behringer BDI21 combined with an ART Tube MP microphone preamp.

It beats watching the news, by light years.

"...
HPF — When CROSSOVER is engaged, the signal just prior to entering the distortion circuit is
sent through a second-order high pass filter. The HPF knob adjusts the cutoff frequency range
of the high pass filter from 125Hz to 1.75kHz, with the frequency increasing as the knob is
turned clockwise.

LPF — When CROSSOVER is engaged the dry signal is sent through a second-order low pass
filter. The LPF knob adjusts the cutoff frequency range of the low pass filter from 60Hz to
10kHz, with the frequency increasing as the knob is turned clockwise."

@basst scho basstalked about his new addition in the pedalboard.
Gate_Hotone
"GATE is a true-bypass designed noise reduction stompbox for guitarists/bassists. No matter what kind of style you are playing, this tiny pedal will effectively keep noise and hum away from your pedalboard without changing your own tone.
The CUT button enables a more harder noise reduction mode, which provides a low cut filter (from 40Hz to 120Hz) and a high cut filter (from 5kHz to 15kHz) adjustable by the two small knobs onboard.
It’s time to get rid of the annoying hum and noise----Keep your pedalboard pure!"

Makes sense, especially given @agedhorse 's stated philosophy on them. Just noting as a point of reference.

Correct, for bass guitar, the HPF works WAY better before features like the deep filter and low frequency EQ.

After considering @agedhorse 's recommendations, I've added the Broughton 'always on' HPF to the beginning of my small pedal board. I also use a Broughton HPF/LPF at the end of the chain (since I have one and do not want to sell) just to round off before going to the board or an amp.

Try it both ways and see what the difference is.

Are you sure here? My research in manuals suggests differently so far...

I'd be very careful with stating all, but at least on the GK models I've looked into, I can confirm that most (not all) HPF-style roll-off happens post FX loop.

It's not the case with Mesa D-800+ and Genz Benz Shuttle 3.0

When I stated that HPF's in amps are always post-effects, I meant simply that if you use effects, as on a pedal board, they likely go before the amp, so therefore almost all HPF's built into amps are post-effects.
And seeing as how we are (or were) discussing primarily pedalboard mounted HPF's, I assumed that'd be a given.
But we shifted to including amps with built-in HPF's, so I can see where the confusion lies.

Oh, I see. My understanding of your point was that you meant effects in the effects loop...

"The Microtubes X series brings the studio method producers have been using the years to cover the whole bass distortion spectrum: from articulate high gain to punchy mild overdrive, raw and gnarly fuzz and everything in between. You now have absolute control in constructing your vision of what the perfect bass distortion texture, definition, and size should have."

Hi Agedhorse,
I just got a used GBE 750, but haven't had the chance to take it out on a gig or rehearsal. Do you know at what frequency the HPF is set?
It seems I might not need my Broughton HPF pedal with this amp.
Ta!

Question: I have an Ampeg SVT3 Pro that has a parametric eq... Wouldn't cutting the lows at 33hz -12db (max cut) effectively be the same as a HPF? It seems that I've seen one or two of the hpf's mentioned here cutting to -12db anyway. Would that not work? (Or ANY parametric eq for that matter, pedal or amp based.)
