So.....Edumicate me on bass HPF pedals.....

[okabass]

So what do you guys have, use, recommend?

If you can DIY this is quite good filter. Despite its idiot name it works well. Schalltechnik has other good value effects like the compressor (made after dbx comp). I've those and they work well.

I use a Neve based (B182) HPF found in pre-amps. It's an old school passive design made up of inductors, capacitors, resistors and a rotary switch. This simple approach sounds good and works well.

Not adding much here, but I will say that my Broughton HPF is the only piece of equipment I will always have with me live now. It has made such a positive difference in how I sound in different rooms and allows my old 15" cab to really punch hard. It tightens it all up and allows me to dial in a boost in the low range. Best money I've spent on gear ever.. best part was it was only $80.

It's possibly worth mentioning many of the current generation multi-effects units have hpf (as well as lpf) amongst their many eq options. Actually, the global eq was one of the main reasons I bought my Helix.

Although the hpf in the helix is variable (either in global eq or any other eq block), I believe it's a fixed -12db per octave, so it's quite natural sounding. However, you can stack multiple eq's (or as I do, low/high cut per patch and low cut in the global eq) to make the roll-off steeper.

I no longer fear dodgy room acoustics!

Just a mention that the f"Deck Series 3 uses two filters. One preset for very low freqs. and one adjustable.

It's probably worth mentioning that a lot of amp heads have a fixed HPF, as an unadvertised feature. So depending on your make/model of amp head, you might already be using an HPF and just not know it.

I personally have the combo HPF+LPF from Broughton. I didn't think I would like the LPF, until I tried it, and now I use it often. I find it is a more neutral/transparent alternative to the tone control on my passive basses. As you point out in your OP, LPF/HPF is a handy tool for putting your bass in the right "frequency slot."

My Rumble head has one at 40, TH 500 low 30s.

Another common fixed-frequency HPF is the sfx micro-thumpinator:

I had one. It failed two times in a year and half. Not recommeded.

The Broughton HPF and a tuner are what I use for all gigs. The Hpf is always on and set to the room . Has made a huge difference in my live sound! Another recommendation for Josh's products .

 

[mikecd1]

It is in effect a variable high pass with additional elements. This was at a time the high pass filters were frowned upon by a good portion of players because they didn't understand how they could help the low end. My have things changed!

I've had my Subway 800 a number of years and wish they'd had the plus version when I got it, but getting the Broughton HPF has been a wonderful addition and allows me to use with other instruments as well as tame boom rooms, not feed my speakers frequencies that add mud and decrease likelihood of failures.

Oh I can and thanks for the link but I've got WAY too many other repair/update projects on my list. I'm just looking for something simple I can buy at a reasonable price and the Broughton and FDeck products seem to be just that.

Sounds like the LFP/HPF on my Calrec modules. Old school indeed, rotary stepped switches (two filters ganged on one dual pot).

Is this some thing you fabbed up from the parts or something you bought?

Sounds like you have something similar. It's a basic signal pathway. I have some rack BAE preamps with them. I don't know if there are kits but there are PCB's for the Neve HPF modules on ebay. I have one for a project long on the backburner.

Some well engineered products here with full documentation: [Invalid or Expired Link Removed]. I like the EQ573.

Actually my Calrecs were racked by Brent Averill, they stopped producing them a few years after I bought them, probably because sourcing old Calrecs was getting harder.

They are actually the entire channel strip, but they put them in their custom built enclosures with of course an external PSU. So it has the filters, three band EQ (stepped frequencies with continuous boost/cut controls), gain (stepped) control of course. 48 volt phantom.

BAE added an output knob, the ability to bypass the transformers, and a phase switch (actually these might have been on the original modules but are on toggle switches on the racked units.

So not exactly something I would take to a gig LOL.

Very cool on guitar, they have a lot of "color" to them so on some things you might not want to use them but what they do, they do fantastically.

They are the middle two modules in the rack below the BR-20 mixdown deck....

Nice set of tools.

I recall Brent buying up all the Neve boards and parts, even mixers that he could lay his hands on to rack them. I like the external power supplies. Mark has done the brand well since buying Brent's interests.

 

[HelpImaRock]

Has anyone used the Parametric EQ on the ZOOM MS70CDR (or other MS pedal) as an HPF/LPF? I know it has a center frequency that can be defined, but that's not the same as a shelving EQ. Also, it doesn't give much instruction on the Q settings. Thoughts appreciated.

 

[6thplanet]

I wanted a blender and HP, so I made my own.

I have extra PCB's if any one wants to mess around.

Well now you know why I go by Analogeezer

I kind of went all full in on mic pres in the mid 2000's because it seemed to me it was about the only future proof technology; and it has been. The Great River and the Calrecs are now worth more than I paid for them; not that I bought them as an "investment" but it's nice to know they are not outdated trash, you know like a non Class D bass head LOL.

Hard to see but the big rack to the left has a four channel John Hardy M-1 (below the Sansamp RBI); that's generally my go to unit for a lot of things, as it's got heft (I had them do output transformers on all the channels) but lots of clarity. Generally all four of the mic pres are rather complementary (the True Systems P2 is in the "straight wire with gain" class) as they don't overlap much at all, well maybe the Great River and the Hardy a little bit but the GR has a bit more "sound" to it.

Great to hear about BAE, I have not paid much attention to the mic pre and outboard gear market for a good while as I am full up and happy with the stuff I already have.

Yes the external PSU's are great, I can't see how you could run that old discrete stuff with a conventional internal PSU that fit into a single rack space but I guess you can since the Great River and Hardy have them. Maybe not with the Calrecs as they came out of a mixing console with a large external PSU of course.

My Averill PSU did fail, but the repair was not expensive. I think part of it is there is no on/off switch so anytime I had the entire rig powered up those things were on.

Thanks that's way cool, I gotta believe there is some connection between Blevins and Mara, given both did/do MCI and were/are in Nashville.

Interesting they sell the 2" 16 track for more than the 2" 24 track, but of course two inch 16 track was probably the peak of analog tape sound.

Years ago I read this story about Heart, they were working on their followup album and the producer (Roger Nichols?) wound up synching two 16 tracks together because a single 16 track machine was used on the first album and they couldn't get the sound they wanted on a 2 inch 24 track.

I had always assumed 24 track 2 inch was everywhere by say 1974 but it turns out not as much. Much of the classic early 70's stuff that became iconic was made on 2 inch 16 track of course.
