Where can I get an easy to use HPF...

Does anyone have a schematic or plans to make a simple fixed-frequency HPF that can run off of a 9V battery? Seems like it shouldn't be very difficult--or expensive--to make: a box, a couple of jacks, a battery, and a small circuit board. Something like the just the 35 Hz fixed filter in the @fdeck Series 3?

Francis has already published schematics for both the v2 and v3 HPFs, he's an open source kinda guy.

I never had the need to use a seperate filtering device...lets put it this way..we are talking about sound frequencies.......those that we..and others.......hear after going through a chain of equipment...beginning at the fingers and ending at the ears after coming out of the speaker cabs..frequency adjustment controls are at different intervals in the chain..at the instrument..at external units..at the amp..and in the mixing console.....so of all those choices..what does one do to make it sound right to their ear where they are standing...?...and what about where others are standing....and how good is everyones ear in hearing a variety of frequencies..?......I am plugging my instrument into a tech 21 preamp..and from there into the front panel of an ampeg SVT Pro 4...the amp has a variety of EQ adjustment points on the front panel along with a nine band EQ section...I am able to get anything and everything I want in relation to frequencies from the pre and the amp...so I can cut or add at all essential frequencies..so I dont need "another" device to EQ the EQ...and I am certainly listening with my ears as I make the adjustments I need for my space and the room..so you can keep stacking the blocks or you can go with the concept of "less is more"..my pre and the ampeg amp does it all..and as stan lee would say.."nuff said"..

I just sold my Broughton and ordered a microThumpinator v2. The microThump is about as simple as it gets. I look at it as more of a "fuse" for the audio path rather than device to remove boom from a room. If that happens, I'll adjust the Low on my amp.

It's interesting to chime in on a thread asking about HPF suggestions and suggest that they are unnecessary, etc.....but, humans gunna human o_O

Thumpenator looks like your best solution for the "easiest" way to implement, but I will throw yet another vote out for Broughton.

I use the H/LPF and love the functionality of it. Didn't buy with the intent on using the LPF but realized sending a DI signal from my pedalboard (with fuzz on it) would sound like a swarm of bees without it. Also, I like the ability to boost my signal from the pedal.

Have had nothing but great results from using a HPF :thumbsup:

He wants something that won't break the bank. Bass amps come with pass filters. They're called bass and treble controls. No offense to the guys that use filters. No offense to the guys who believe their controls should be left at noon. But I also never in 35 years used a filter. No point. My amps have them already. In shelving bass and treble controls. You can save cash by just reducing lows at higher volumes. You can get way scientific, buy cabs that respond to the frequency points of yer amp, say the typical rolloff of a cab is 40 hz, buy an amp with a 40 hz shelving bass eq point, and there's your filter. Bass, treble, parametric eq, graphic eq, are all band pass filters. And plenty of great tones were had, still are had, by pros and regular guys alike, with no filters. I have filters on my power amp. But it is easier, better sounding, to just roll off what I don't want with eq. And you put money back in your pocket. The OP asked for a cheap solution. Using your amp and bass' electronics controls are it. I happen to agree with Mr Blaze Barlow. Filter? Heh. Amps already come with em.

HPFs are not shelving.

Without proper punctuation it’s just the incoherent ramblings of a mad man.

HPF/LPF is an effect. Some people use effects, some people don’t. They aren’t for everyone. I’m not a big effects guy myself, but I’ve been interested in picking up one of the Broughton always on units. They rarely stay up in the classifieds for long on the rare occasion a Broughton pops up.

Actual links to where I can order is much appreciated.

I should mention that this is for live gig use.

You can't beat the simplicity & sheer effectiveness of the sfx Thumpinator. Plug & play = sonic delight.
If you need a LPF , just turn your Treble filter down, I have been told that's what they are for.

They’re cheap enough brand new. Go for it!
