So a question for you guys N girls who have variable HPF in your chain, what frequency do you normally set it for ?
It depends of the slope of the HPF, and how you dial the EQ on top of that. A first order HPF, 80 or 90 Hz is fine. A fourth order HPF ? Not above 40 Hz... But the use of these two is different : for the first one it's a sonic preference, and the second one is here only to protect the cab. Different filters, different uses.
 
The nobelium HPF will be 6dB on any frequency I set it to, I was thinking about 90Hz and 60Hz since I only have a 4 string bass and so does my daughter.
(We will both have fEarful 12/6 cabs as soon as I build them, got all the parts ready)
My problem is I might send the pedal to a friends son who gigs live and I am not sure what he plays, I have seen a 4 string on the video clips from the songs they have released.

The Broughton is 12dB slope, I might have 5 PCB's I just got made that is the same but will fit in a 1590A without a battery or a 1590B with a battery.
Its the one with HPF, LPF, Gain. ( This is why I have ask Nathan to keep his schematics hidden from the rude DIY people that copy everything, me included)

Nathan uses a nice gentle -6db/octave slope on the HPF, and I think that's part of the reason it starts as high as it does. This works great on my 4 string with a gentle bass boost upstream.

The Broughton HPF (and the HPF on the Empress ParaEQ MKII Deluxe that I'm running) cut at twice that rate: -12db per octave, and I usually end up setting it in the 50-75Hz range.

Adding a resonant boost at the same frequency you're cutting does A LOT for the percieved low end. I was messing around with this on the Quilter BB802 I picked up. It has a fixed bass boost at 100Hz, and setting the HPF there with a strong bass boost felt GREAT compared to no HPF/lower boost. The resonant bump also added a nice heft to my higher strings while the HPF cut kept the low E from feeling like too much as it often does. Much more even across the board.

Just dialing in by feel my ParaEQ ended up with the HPF/resonant boost (+9db) at 80Hz. But I play 4 strings, so ymmv with a low B in the mix.
 
I think the style of music one plays can also have an impact on what defines a "useful" frequency cutoff for an HPF. For example, the vast majority of the music I play is reggae, and modern soul/RnB; the bass lines emphasize HUGE sub frequencies, and a lot of the information from about ~40Hz to 100Hz, which a lot of guys here consider mud, is pretty crucial to getting "the" bass sound of those genres. In a rock/punk/heavy context, or in a folk/country/jazz context, I have found that one can (and should) probably be a little more judicious about the sub-100Hz frequencies.

So it's probably impossible to make sweeping generalizations about how and where to use an HPF. But this is TB; sweeping generalizations just come with the territory LOL.
 
I guess the HPF setting is also dependent on what speaker cab you use, some can not handle very low frequencies very well at all and sounds muddy earlier.
I guess if you only go to FOH or are doing a recording a HPF will be best left to others since you don't want to affect their equipment, especially if FOH has a massive sub setup and can handle all the lows.
But I'm just a home player who spends more time building gear then playing.

This is why I didn’t use the HPF on the Finally. It was last in the chain. If I had my amp it was fine, I could adjust eq there, but it was a little too thin going into FOH. HPF at FOH is set much lower than that, around 50 I think.

WRT to variable HPF settings, any from 60hz to 120z for me. Depends on where I am. Decent stages will float between 60-80hz, but I also jam in a small basement, really loud, with up to 3 guitars. It's there that I crank it up to around 120hz. I am, however, always boosting bass downstream the HPf. The day I learned I could do this changed everything.
 
HPF setting is depending on too many factors for me to be specific for any application. Variables include instrument and signal chain, amp and speaker and the overall mix of a particular venue and band. As bass players we are far more sensitive to lower frequencies and pitches than other musicians and most engineers. I don't record using a HPF instead leave that to the mix and mastering engineer to handle such things as I do when I am mixing a recording, it can really tell in that context.
On my live pedal boards I have used an [sfx] microThumpinator going into either my powered Alto speaker or GK MB500 into a 1x15 Walter Box with a BW speaker. I do switch to a Broughton HPF when using a sealed 1x15 to keep the cab from burping.
 
I’ve never felt the 90hz HPF on my Neptunium sounded bad, just boost bass into it and all of a sudden you have a tight full low end. Tim Lefebvre has been known to dime the low knob and engage the HPF for a “Motown” sound on the Noble DI and I don’t think many people are turning his services away
 
So a question for you guys N girls who have variable HPF in your chain, what frequency do you normally set it for ?
When recording direct, I set my Broughton, (-12 dB per octave) between 40 and 50 Hz. This is mostly to improve the signal/noise ratio of the preamp. After that it is straightforward to add an HPF in the box when mixing, tuned based on when the kick lies. Live, when playing through an amp, I may set it a bit higher if the acoustics are too boomy.

I still have a "Dreamcatcher" tab open in my browser, someday?...
I cannot resist being a horrifying enabler……today I was practicing for our office Christmas party…red channel duuurt for Suffragette City then click to blue (UA) for Superstition…..

Once Dreamcatcher got mentioned I knew you were going to comment. If there is anyone who sings this pedal's praises it is indeed you and rightfully so; it's a versatile piece of kit
 
I have a new More with the upside down mounted tubes, I tried swapping 3 different tubes into the right side socket (I'm Assuming that was the input side), it didn't sound good....it got very compressed and started sounding squishy. So I simply put the original tube back in.
I wasn't looking for any drive or dist, was trying for more bite like what I got from my Wesinghouse I had before the More, my Finally also has that same bite.
Anyways, just been gigging it, and on stage in the band mix the notes just sound thicker and fuller out my class D amp.
If you're looking at the circuit board, the right side is actually the buffer and the left is the one for the preamp on More.

its WAY too high. but the Noble DI did it so now its a good idea, or something.
I need everything over 60, and nothing under. I wish this requirement could be considered by someone, someday, post eq and pre-di.
I have some great news for you, but I unfortunately won't be able to tell you until January.

A quick followup. I had issues with my Grand Slampegg : it made some noises. I guess that the tube was microphonic, as I could ear thumps in the amp when I tocked the pedal. Today I changed the Sovtek 6SL7 with an JJ 6SL7. It was a bit difficult because the tube is bigger, but it fits. Now the GS is dead silent, and I guess the sound is a bit more defined. So far I'm pretty happy with the change...
Good to know, thanks for posting this. I had two Sovtek 6SL7 that were microphonic right out of the box so it got pulled, but I hadn't had any issues since. Maybe I'll grab some more JJ 6SL7 (not sure what happened to the ones I swear I had) and do some side-by-side testing to see if JJ would be an option if Sovtek proves problematic.

Also something I wasn't aware of, Sovtek doesn't actually manufacture 6SL7 anymore, somehow I missed that all the tubes I was buying were NOS. Which means the supplier will have to run out eventually, so if the JJ's sound as good then I can sleep easier at night.
