Old Ozzie Guy Posted March 28, 2023 Share Posted March 28, 2023 Hi all, I'm asking if any one knows of any "high pass filter " (variable, passive) IV been trying to find HP(brand name) passive hpf, but can't find anywhere. Any clues? Or any other brands people know of? Thanks Quote Link to comment Share on other sites More sharing options...
Jakester Posted March 28, 2023 Share Posted March 28, 2023 Not seen a passive HPF, but there are F-Deck clones out in the wild - one recently sold on the classifieds here, and they're available new here: https://reverb.com/uk/item/13880879-rafferty-hpf-pre-2-bass-preamp-adjustable-high-pass-filter-phase-switch-custom-color Quote Link to comment Share on other sites More sharing options...
Greg Edwards69 Posted March 28, 2023 Share Posted March 28, 2023 Google just found this for me.

Baloney Balderdash Posted March 28, 2023 Share Posted March 28, 2023 (edited) It's very easy to make your own passive HPF. Basically just a resistor pot and an adjustable capacitor with the right range, or if you don't need it to be adjustable simply just a resistor and a capacitor of the desired value, and then of course 2 mono jack sockets, some wires and some sort of box to fit it all in. Regarding active HPF's I find it strange how few companies actually offers a stand alone solution for this in a pedal format. The cheapest solution on the market for getting an active HPF would probably be buying a Zoom G1 Four or B1 Four, which both features a HPF model. Personally I use the one build into my NUX MLD Bass Preamp + DI, set @ 40Hz, previously using the switchable build in HPF fixed @ 40Hz of my ART Tube MP Project Series tube preamp.

The slope (3 dB/oct) is a fair bit shallower than the common ones for bass, so depending on what you want it for, it may be too subtle. Micro Thumpinator 2: 36 dB/oct VONG-Filterung: 12 dB/oct variable and 24 dB/oct below 30 Hz Fdeck HPF-Pre: 12 dB/oct, or 12 dB/oct variable and 24 dB/oct below 35 Hz on the series 3 models Broughton HPF: 12 dB/oct Mini-HP-VONG: 12 dB/oct I'm guessing there's a limit to what can be achieved without a powered circuit Edited March 28, 2023 by MartinB 1 Quote Link to comment Share on other sites More sharing options...
Greg Edwards69 Posted March 28, 2023 Share Posted March 28, 2023 (edited) Ah, I didn't actually look at the details, my bad! But yes, that is rather shallow to be useful for bass guitar. The low cut control in my Helix is 12db/oct. I frequently stack two of them (one fixed frequency per preset and one variable frequency in the global eq) to get a more drastic cut.

I assume the active HPF that they are running in the effects loop of their amp currently is for filtering out unwanted sub bass, to get a tighter bass response and have the amp and speaker work more efficiently, whereas he passive HPF that they are asking about here and plan to place first in their signal chain is primarily for tone shaping purposes? Sort of like an extra, but working in reverse and being more flexible, and possibly switchable too, external (reverse) tone pot.

fretmeister Posted March 28, 2023 Share Posted March 28, 2023 If it's on a board with a power supply, why does it need to be passive? 2 Quote Link to comment Share on other sites More sharing options...

I mean, a *proper* HPF used for tone-shaping purposes isn't really going to be doing much that the subsequent one in the FX loop won't already be doing.

I mean, a *proper* HPF used for tone-shaping purposes isn't really going to be doing much that the subsequent one in the FX loop won't already be doing. A passive HPF will introduce resonance peak, not really the same as a regular EQ pedal at all. Also how exactly would a passive EQ be less complicated? You might as well ask why they just doesn't swap strings or use the amps EQ instead. I don't know what it is with certain people being so eager on various OP's getting it all wrong, and that they should rather do it their way, cause certainly that is much better and not least not stupid. It's like these people presume that people don't know what they are talking about by default, frankly it's rude.

Old Ozzie Guy Posted March 28, 2023 Author Share Posted March 28, 2023 U probably right, just the studio side of me keeps ruling my thought process.. it's not for tone really, it's to get rid of woolie bottom from hofner being O/driven, And to get max vol out of Ampeg Micro VR with 1x12..

Ah, well, in that case I would say that the people here pointing out it not really being the right approach would actually be right. Get a more efficient active HPF to place in the effect loop, an extra one, or set the frequency of your current one to cut at a higher frequency.

Sort of like an extra, but working in reverse and being more flexible, and possibly switchable too, external (reverse) tone pot. I use two in my Helix - see my post above. One is at the end of the signal chain in every preset - this is set around 50hz to tighten up the low end and protect my frfr and PA speakers (we don't use a sub... yet). I have another hpf in the global eq that only affects my frfr speaker on stage, this one is variable depending on the venue to control any boom and rumble on stage without affecting the PA.
