Fdeck's HPF

[caeman]

I had Max at (sfx) build a low-pass brickwall filter for me. It whacks those annoying high frequencies above 5kHz.

[astack]

Nice! A Hissinator?

Fixed at 5k or variable?

[caeman]

Fixed. Since mine was the first, I got to name it: Micro Screaminator. It removes the screams, like the Micro Thumpinator removes the really lows.

I use this every gig now.
Set whichever rig up I'm using, "spin the hz knob til I feel the fat fall off a bit" and then set it so it's just before that starts happening, and, done.

That falloff spot seems to vary by rig, bass room, but it also seems easy enough to find.

The end result seems to be "more punch, more clarity, less gain required."

What a deal.
I've been running in the fx loop of both the GK MBFusion and 1001RBII.
Just works; what else do you want?

Same here. I was trying it out in front of the head, but later switched to the FX loop.

The Thunderfunk has to Effects loop, one before the EQ and one after. I run it in the first loop. Works great!

I got to play with this today and preferred it in the FX loop as well. It just seemed more transparent in the loop as opposed to the front of the amp. I haven't really used this HPF on a gig yet as I haven't really felt the need. I've been running an EDEN WTX-500 and it always seems to sound good to me with some minor EQ'ing. I'll need to squeeze every last clean db out of the Eden this Friday night at a sans PA support rock gig.

I'm not expecting much in the way of added headroom but I'm going to find out if the HPF will help. It did give me more perceived volume on my SWR SM400S but I think that's just because that amp doesn't seem to have any form of HPF at all on it. I don't think that's the case with the EDEN WTX-500.

The last time I did this gig my WTX-500 and Berg AE410 were pretty much maxed out all night. On a side note, the amp was still cool to the touch at the end of the third set. Amazing. I love Class D power supplies!

To turn off this HPF do you just turn the volume all the way counter-clockwise?

Or... ?

[caeman]

It cannot be turned off. Why would you want to?

[Jazzdogg]

Fully clockwise cuts frequencies below 35 Hz.

Fully counter-clockwise cuts frequencies below 140 Hz.

At "noon," frequencies below ~70Hz are attenuated.

If you mean power down you have to remove the patch cord from the Output jack. If you mean bypass the circuitry while still being connected to the amp, it can't.

[::::BASSIST::::]

Bummer. I am wanting to mount this onto my small pedal board which will make it difficult to disconnect once everything is wired up. There are instances when I want full range with no attenuation such as playing in dead rooms that suck out the bass.

So I am guessing if the DC jack is unplugged the signal will not pass thru this device?
For example, if I had:

tuner > hpf > preamp with the dc jack unplugged on the HPF the signal would not get thru to the preamp?

[Chef]

I don't think you'll hear any effect from it in your signal chain at all until you have it set to 50-60hz or higher.

[::::BASSIST::::]

Hmmm... well I tried it the other night at rehearsal, but the room was very bass unfriendly so I decided to unplug it (hence my question about turning it off) and as a result got back some needed low-end. This was playing thru an Ampeg 810, Tone Hammer pedal and QSC 2402. Again, it was a strange room with carpet and absorbent materials everywhere. Way too small too.

[Chef]

Hmmm. It surprises me that, if you it set at 35hz, and volume all the way up, that there was that much of an audible diff.

I don't use any cabs that are like an ampeg 810, so there's that.

[kringle77]

Must have been a weird room. I've run my series 2 using an ampeg 8x10 and it really removed the woof that I hate in that cab. Made it sound more similar to the nv610, just less mids and more top. I'd love to see Francis put out a bandpass filter with controllable highpass and lowpass. I think that would help alot of guys get a more traditional, sealed, one-way cab vibe with modern cabs.

Now THAT gives me GAS. Same filter on the bottom and a gradual slope(variable) on the top.
mmmmm......thoughts.

[caeman]

Francis has stated before that he doesn't want to change the design to include tone or other features, so to get a variable LPF, it would have to be a whole new box. If you have both in one box, it is then called a Band-Pass Filter (BPF). I would certainly dig a BPF, as I could then retire the Micro Screaminator LPF off my board and keep to minimalism.

I guess I'll put it at the end of my signal chain on my pedal board and just unplug it when needed. I can put my Tone Hammer in front of it which fortunately has the jacks at the rear for easy access and not on the side which makes things difficult once things are velcroed in.

[astack]

Maybe some kind of splitter/bypass box? I think one of our guitar players has something like that.
