Anonymous 's review"It's THE ultimate tool !!"

Stone Deaf FX Parametric Distortion Filter PDF-1
The PDF-1 is :

- a full parametric filter
- a soft clipping drive with parametric EQ
- a preamp
- a GREAT tool !

2 knobs : Height and Freq.
One 5-way position selector : to choose your Q between Thin and Fat.
One flipswitch : Clean or Dirty channel.
One footswitch : Bypass/ON.
One 1/4inch jack input.
Two outputs : you can have one channel each or both channels on one output.


Very easy to use and understand.
No worries !

It's all analog, so you turn a knob and magic is here !

Use it on guitar, bass, drums, mix, keys, and even your dog if you want.
Your dog will sound THAT great with it. =)

If you want to make choices for your sounds, but good choices, try this box.


The sound is pristine.
Dynamics are respected and magnified.
Everything you plug into it will sound better than ever.
You can add 2dB or something for light improvements or you can simply boost as hell and give some mojo to your riffs.

I use it with bass, I use 2 of them.
One for clean and full lows, the other for dirty or clean mids.
It's shiny into my funk-stoner project !

Experiment with a lot of stuff, sure you'll find a great way to use.


The PDF-1 is one the greatest tools I've ever had !
Last time I was in love for a piece of gear was for an API 7600, so to me the PDF-1 is one of these tools you bring on a desert island, definitely !
(I'd bring two of them !)

I don't what to say except thanx to Luke for building this, it's a real improvement for my recordings and I'm done for searching my bass sound : I GOT IT !!

Ronmo's review (This content has been automatically translated from French)" Queens of the stone age!"

Stone Deaf FX Parametric Distortion Filter PDF-1
anlogique pedal, that mixture parametric equalizer and distortion / boost


Configuration is very simple, clean mode and a mode dirt (drive)
A knob to select the frequency of 65 Hz to 3 kHz, another to choose between boost and cut up to 20 db and a 5 position selector to choose the bandwidth


The sound is really excellent whatsoever mode or clean dirt, it can be used to correct defects or radically change the sound, very effective with all styles of guitars or amps.
It is equally effective boost to showcase a solo or a riff that is engaged all the time to transform or improve the basic sound


It's really a great pedal that can multiply the palette of sounds available with his gear, it can be used to cut frequencies to sound in a mix, add frequencies to transform the basic sound or experimenting with new textures by adjusting the frequencies and mode dirt.

Stone Deaf FX Parametric Distortion Filter PDF-1
I will not repeat what has been said about the effect but I remember his original name for Google lovers and long evenings reading about the effects: Maestro Parametric Filter. Lovers of "" analog, Luke remained faithful to the original model but was optimized.

Very simply, this is not a fact but one of three effects, namely a Booster (20 dB), distortion (very well calibrated), and ... an equalizer (Polyvalence!). If my ears do not deceive me, just listen to "Better Living Through Chemistry" and Queens of the Stone Age to get acquainted with the unit (or the whole Rated R Album, or Rush (Mr Lifeson)) .

The PDF is for me very "Plug and Play" and it's very enjoyable. Two questions arise when it is turned:

- Around How often will I play (Freq: 65Hz-3kHz)?
_ On what bandwidth do I apply (Bandwidth: "Thin" to "Fat" (5positions))?

Its simplicity hides the details very well thought out. The two-color LED that lets you know on what "channel" (meaning path) you are. Green Clean, Red: Dirty, auxiliary output, easily accessible with the battery drawer (Alim Boss type 9V) Footswitch inclined ... it sounds silly but it's convenient and it is not impossible that the life of the switch to be increased.


Hi, I'm easy *. Each order is clear. Bandwidth knob: left "Thin" right "Fat." Etc, etc. ...

* If you do not're doing, sell, buy a triangle. :-)


Here we go ...

... When I lit the first time, I thought, "Yeah, blah." But that's because I'm a moron. Why? Because I have an amp 18watts quality (it's not for me fart but it's easier to be objective about the quality of the product) and I played cushy low volume. I got tired, I opened the pedal, saying "it is not possible firecracker welding is poorly done." Nothing at all and by the way the work inside is remarkably clean. So I pushed my amp a little ... HELLO MADAM, I welcome you on my pedalboard!

It is simple for me to stay in what I say. Given the number of options, the sonic possibilities are many and therefore one of the many sounds will probably please you. Personally, it is the originality that made me turn to this pedal. It complements my Suhr and Fulltone effects mainly.

To test urgently with your stuff!


It is certain that Luke is working and what he does, he does it very well. The sound "vintage" without seeds pedals of yesteryear. Pay the fragility of a minimum 300EUR Maestro is a choice ... An odd choice. The PDF-1 is 149eur (Belgium). Mass is said, at least for me (I told you I was an atheist? Sure, that nobody cares).

My two maximum scores refer to my choices. I think this is perfect for me. Beyond that, it is clearly a great pedal, no one should deny it.

Stone Deaf FX Parametric Distortion Filter PDF-1
As mentioned in the previous opinion, it is a clone of Maestro Parametric Filter.
So it is a fact that can walk on a frequency range of 65Hz to 3kHz, applying-20dB to +20 dB, while choosing a Q more or less pronounced.
In addition, you can add a drive (type soft-clipping) which is really nice to add character to your scratch (or other)

I put 8 / 10 for my use because I have to add some options, but the pedal is fully exploited like that! It's very well built and it exudes quality "boutique".


2 knobs:
- Frequency: choice of the center frequency adjustment.
- Height: -20 / +20 dB

1 switch 2 positions for choosing Clean / Dirty (normal and drive).
A 5-position switch for choosing the Q (thick or thin).

1 footswitch for on / bypass.

We can not be simpler and more explicit, we're going straight to the point.


There is bluffing!
To be tested on scratching, bass, voice, taken battery, keyboard, etc. etc. it's just HUGE!
Have the opportunity to give some color to your instrument without losing its character and timbre, it is simply the best.
Once you make a choice with this, clearly, but it can allow you to really bring out the most important frequencies and suddenly place you better in the mix, either live or in studio.

A very serious tool that simplifies and good life.

For bassists who want to blow up the subs, Luke will release a version that will go down to 30Hz, it promises to décoiffer!

For my part, I ordered the second, when it was a between the legs, we want to open!


It's been a lil time as the guitarist with whom I played and I just use it only to discover that it was the tool I needed for low and duplicate!
Of course, all the bass players do not approach a hack and research in the effects, but for my apple it goes like that, I do not have this amp and I have even less need. It's simple, the last time I took a slap sound that was a slice level API ...
Frankly, try this, it's worth it!
