HPF (I think) demonstration on youtube?

On one thread that flew past me maybe a week ago, someone posted a video of this magical effects box that, when engaged, wouldn't change the sound recorded by the microphone to my ears but you could see the cones of the cabinet doing much much less work. Nowhere did it mention it was an HPF, but I assume that an HPF was a large part of its secret sauce.

 

I now cannot find the video, nor remember the name of the box. Does anyone know what I'm talking about? I think it was either a 4x10 or a 6x10 in the video.

Amazed there isn't a larger market for this kind of thing. Who wouldn't want to make their kit last longer and make their sound sound better?

 

I had to laugh at one comment on the YT vid which said they wouldn't buy one because they couldn't hear the difference.

i think there are a quite a few people on Basschat that use a HPF, and i'd guess that a fair proportion are using the Micro Thumpinator as they used to pop up in threads all the time (and occasionally in the for sale section)

I'm using an adjustable HPF that i built from a kit after hearing about it in the DIY effects thread. it was very easy to build and works really well. 

 

Mini HP Vong kit

 

I'm actually thinking of buying another as i have 2 different pedalboards and want one for each.

Lots of amps have one built in anyway, but it’s not easy to discover which ones. I recall a thread on Talkbass with Agedhorse, a designer of Genz Benz amps talking along the lines that all their amps had such a filter but they never marketed the fact.

yeah i remember a thread about this, i think that my markbass F1 has a built in HPF but i also run straight into the PA at church so added one to my mini church board as a precaution, if i add one to my main board it will mainly be used as insurance for any time i'm not using my amp (or if i end up buying another head) the one i linked too is pretty cheap compared to a thumpinator and imo worth it as belt and braces insurance if i'm using a house amp somewhere or sharing a rig with another band.

Darkglass have one as standard on their amps.

HPF’s are all over the place. Amps can often have them built in, and many pedals have them as part of their circuitry. 

In all my years of playing ive never had my drivers jump around like that, and dont know anyone that has.

 

its not a gimmick, but not a necessity either, at least for most of us.

Yup! As you say, My fave amp has a variable HPF and LPF, some of the major effects units I have owned such as Helix and Quad Capture have HPF blocks in them, there are SO many amplifiers on the market that have HPF's in them by design - guitar distortion pedals definitely have them in as a "pre-EQ" requisite (hence why you don't get much low end out for bass out of some). 

 

I agree that it isn't a gimmick, but, like signal limiting and over heating/short-circuit circuitry, an HPF is useful feature to have on board. Especially for those scallywags in rehearsal rooms that crank the bass control up to the max lol.

If you add quite a bit of saturation to your signal (but not necessarily so it's heard as audible distortion) - you'll soon get the drivers jumpin'

You're right though, when playing through them clean, drivers don't tend to do that - and as pointed out earlier in the thread, a lot of amps have HPFs built in because it really frees up the headroom in the amp.

The kind of HPF that sits unannounced on board amps is better described as a Rumble Filter. The Thumpinator likewise.

 

Take a variable HPF and turn it up until something sounds missing. Then turn it back down until it isn't. In my case it winds up somewhere between 60 to 70hz with 5 strings. The low B sounds full without being flabby.

👆This! 👍 +1

Further, having found a sweet spot for the HPF you can experiment with the bass knob, which may change the optimal HPF spot a little. You might well find it gets more bootilicious with a little more bass and a tweak up on the HPF.

 

The problem with that is you wind up competing with the kick drum and 80hz turns into mush.
