Fdeck's HPF

I wanted to simplify my set-up by velcro-ing the HPF to my combo amp, and using a battery, and leaving neat cords plugged in.

I took the end of detachable AC adapter cord (the elbow tip that goes into the HPF, not the end that goes into the AC outlet) and tied it to my amp, and now use it as an off switch (and so it does not get lost on stage). The end that goes into the outlet not present.

When the tip is plugged into the HPF, it bypasses the battery, even when there is no power- no power, the HPF is off. Cords are present at both the input and output.

At the gig, before I turn on my amp, I unplug the tip, battery is not longer bypassed, and the HPF is "on", battery powered. I could also, I supposed, plug the adapter into an outlet to turn it on and off (after the amp is off).

Hope this helps.

You could also probably use something like this:

I use them at home everywhere!

Nice idea,

setting of the variable 12dB filter to 35 Hz the filter characteristic calculates to 24dB/octave @ 35 Hz

setting the variable filter to 70 Hz then the characteristic calculates to:

12dB/octave @ 70Hz
24dB/octave @ 35Hz

Signal content below 50 Hz is in general negligible.

But it's "electrical" not negligible because of increasing excessive cone excursions below 50Hz.

...chuff


BTW:
Did anybody considered an improved RMS power handling of a given cab?

It wont work because the signal will not pass thru the HPF if it does not have power.

Right?

That's a really nasty sound indeed ...
But cones reflect distorted sounds very well, and it all depends on potential power/voltage if the driver is gone or if it is only a nasty sounding "clack"

But indeed there are some folks out there that are playing with a very low string action very narrow to pickups and a huge eq bass boost and extreme percussive playing technique, the string clacks on the pickup (or fretboard as well) and the voice coil hits the back plate just the same moment...

And some folks are wondering sometimes about faulty drivers ...

If by "it won't work" you mean it will work as an off switch, it does. You are correct- when it is unpowered, no sound.

It can be confirmed (I think) because while the output cord is always plugged in, and the battery is always in, every time when I remove the "end tip", the red light flashes on for a moment, showing that the battery has power- and it works.

After acting as a middleman for quite a few HPF-Pre units, I am finally buying a Series 3 for myself. I have a Series 2 attached to my U-Bass, but I have been curious to put a Series 3 on my Gretsch's FX board permanently. It should be an interesting setup.

Gretsch -> HPF-Pre -> Micro Screaminator -> DI

[inmate13]

How would i get one of these in Europe? Slovenia to be more exact. I am leaning to buy Fdeck or Micro thumpinator for using low B all the time. I havent decided wich one yet, but i can order SFX anytime, just wanna know how is it with Fdeck.

[caeman]

You find a middleman -- like me -- with whom to deal. You send the middleman the money via PayPal to cover the product, and shipping to you.

I'm putting my Fdeck HPF in the effects loop of my Sansamp RPM.
Line 6 receiver > MXR M87 compressor > Sansamp RPM input (HPF in effects loop..after tone controls/before main output control) > Peavey IPR1600 > GK NEO212II.
Should be here any day now.

Hooray! I finally own my own Series 3! w00t. I have a Series 2, but that one is attached to my U-Bass strap. I don't use any additional pedals with the U-Bass, so it makes for a convenient setup. The Series 3 is for my Gretsch and it will be living on my PT-Nano. It handles the power of my TV Jones humbucker without blinking and cleans up the extraneous low end growl that muddies the sound of my fretless short-scale wonder.

The Middleman finally gets his own - congratulations!

Lately I been feelin like I am putting my basses through too many boxes, just to get my standard sound, without even adding effects. So at sound check yesterday, with my Stingray 5, I plugged straight into the amp. I was immediately struck by how pronounced the "th-k" on the attack of every note was, and how since April (when I got my first HPF-Pre) I have gotten used to my sound being so clean on every note I play. I have used it on every gig, every instrument since I got it. I put the HPF-Pre in front of the amp and it cleaned up and went away. With this band I wouldn't say my sound is overly bottom-heavy, but that few milliseconds of the finger pulling and releasing the string really sends out some messy stuff that I have been spoiled not having to deal with any more.

I had series 3 set all the way open (35) and volume max, fwiw. My electrics prefer that one. I typically run the filter all the way open unless the volume gets high and/or the room needs more cleaning up of the low end.

I will pare down my signal processors to the minimum of what I need for any particular situation, and I plan to build a smaller pedal board soon, but one constant remains: the F-Deck. Generally series 2 for the upright and series 3 for the electrics.

[caeman]

I rarely get the chance to use an amp, so the HPF-Pre will always go into some sort of overdrive pedals, to add a touch of hair.

Got my series 3 today. I love that I can use it in the fx loop of my amp with out it overdriving like my series 2. I have another series 3 being built into a custom rackmount di with a Sansamp VT2 and a custom 1 band semiparametric mid. Basically the ultimate amp sim di. Oh, it can be phantom powered too!

Sweet. Are you just having all the guys of those put into a single unit? Or something more crude like mounting several actual boxes in a unit?

[kringle77]

An actual custom rack.

[TimWatson]

Interesting. Is Francis building the series 3 portion?
