KATASTROPHE


Katastrophe - Sludgefest Dominator

 

We set out to create a pedal with the gain circuit based on the sound of a highly modded British full stack - but with a more effective EQ section that will work on clean and dirty amps alike. As per usual, we couldn't resist shooting way over target, resulting in the Katastrophe. 

 

The Katastrophe is a well rounded, articulate distortion pedal that complements a diverse range of playing styles, built to work perfectly in front of the amp, but also as a preamp pedal into a power amp.

Controls and features

Enabling the player to retain fidelity as well as drastically reshape their signal - and to do so conveniently - has been a crucial objective in the KATASTROPHE's circuit design. Thus, the pedal comes equipped with an assortment of external and internal knobs, Bobs and Sallys for radical manipulation.

Volume determines how hard you push the amp, or how loud you want your setup to be when using the Katastrophe as a preamp. Gain is pretty self explanatory as always and so are the EQ controls Bass, Treble and Presence, with presence controlling higher freqencies than the Treble knob. The externally located low cut will remove low rumble, if you wish for a more modern high gain sound, or to go full doom with all the low end untouched.

The analog Octave Up section has more gain than the usual octave up circuits and is identical to the one found in our Silvermachine. An added foot switch for this circuit offers players more flexibility and allows for more drastic changes while playing.


Internal adjustment options

- The internal Highcut switches let you control the highs even more than you are already able to, with the Treble and Presence knobs

- You can also boost both the low end and the dry signal independently and in parallel, providing a versatility that will satisfy even the most discerning audiophile bass players out there (you know who you are)

- The Postgain trim pot lets you adjust the Katastrophe to function at its best with your pickup output.



Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 12 x 15 x 6 cm with knobs

- Power requirement: 9 V DC PSU (centre negative, 2.1 mm), this pedal includes an internal 18V charge pump for higher headroom

- Current draw: <50 mA


Please notice

Experimenting with the internal Postgain trim pot will make the Katastrophe ideally suited to your pickups with as little noise as possible.

WARLOW



Warlow - Fuzz Monstrosity

 

Gather around and feast your sensory organs on our latest venture into a world welcoming of soft sustaining leads and wallshaking doom sounds alike: the Warlow.

 

This device is our take and dedicated interpretation of an op-amp based, Pi-style fuzzstortion/distortiofuzz pedal which authentically captures the late '90s Seattle-based grunge texture and tone, also featuring additional toneshaping options.

179,00 €

  • Fast Shipping!1

Controls and features

The Warlow incorporates LED clipping diodes which bring about a very pronounced low end and a truly barefaced fuzz. As pictured, it features Volume, Tone and Sustain controls, but it also has an internal switch to change the behaviour of the tone filter.

Volume controls the output volume of the pedal, to set how hard the amp is pushed or how loud the pedal is. The Tone filter lets less high frequencies pass through the pedal as it‘s turned up, similar to the Rat pedal. It can also be switched internally, as further explained in the „Internal adjustment options“ paragraph. You can adjust how much gain you want, by using the Sustain control. It ranges from smooth overdrive sounds to immense amounts of distortion/fuzz.


Internal adjustment options

- Switch between the Muff and the Rat style Filter. If the switch is in the position towards the jacks the Rat style filter is engaged, having it towards the footswitch selects the Muff style filter. We ship them with Rat style filter selected.



Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 12 x 15 x 6 cm with knobs

- Power requirement: 9 V DC PSU (centre negative, 2.1 mm)

- Current draw: <50 mA


Please notice

To get the typical Muff sound, the Warlow into a clean amp is the best option. If you want to use it going into a dirty amp, we recommend using the Rat style filter. But as always, there are no rules!

TESLA WOLF V2 



Tesla Wolf V2 - Ultra Versatile Overdrive Pedal

 

We are proud to present our new and improved JPTR FX classic: the Tesla Wolf V2. A completely overhauled version of our highly versatile and surprise packed Tesla Wolf Overdrive in a pedalboard and user friendly enclosure with even more usable features than its successful predecessor.

 

The Tesla Wolf is more than just an ordinary overdrive. It covers ground in anything from vintage to modern overdrive throughout fuzz history, with an impressive tonal range and variable/combinable clipping options, making it one of the most user oriented and versatile drive circuits we at JPTR FX have had the pleasure to design.

179,00 €

  • Fast Shipping!1

Controls and features

The predecessor of this pedal already featured the Volume, Gain, and Tone controls of this pedal, which adjust how hard you push the amp, how much gain the pedal creates as well as adjusting the broad tonal range this pedal accomodates. The Tone control contains everything from thick, earthy lows to ear piercing highs – perfect for making your guitar signal sit in the right place within a mix, whether dampened or present. An extensive and generous Gain control allows the pedal to be used anywhere between subtle overdrive and sputtering/gated fuzz settings, while still maintaining a very dynamic and touch sensitive response.

In addition to existing features - we have further added an internal Bass control which offers the capability to dramatically increase the low end output.

The Tesla Wolf also now has a Dry Volume control, which allows for a smooth addition of your unaffected input signal on top of the overdriven/distorted signal.


Internal adjustment options

- The Bass boost allows you to go from tighter distortion sounds to thick fuzz sounds. Yes, this thing can be felt in the room.

- The Tesla Wolf also includes three internal dip switches to dramatically alter the gain characteristics of the Tesla Wolf through the addition of diodes and LEDs in the circuit. The dip switches can then be set according to taste, turning the Tesla Wolf into a four in one multitool for any dirt pedal application.



Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 6,5 x 13 x 6 cm with knobs

- Power requirement: 9-18 V DC PSU (centre negative, 2.1 mm)

- Current draw: <50 mA


Please notice

Due to its immense volume, this pedal works great with tube amps and set ups where you want to push the next gain stage in the signal chain. On very clean, high headroom or transistor amps this pedal will get very (VERY!) loud and not saturate the input stage.

JIVE



Jive - Reel Saturator

 

Inspired by an old Akai GX 210D reel to reel tape machine from the 1970s, the Jive - Reel Saturator was made to give you the gooey and warm saturation obtained when pushing the Akai’s pre-amps to the max.

 

This pedal is bold, gritty, present and simply chock-full of screaming old-school mojo. If you are into lo-fi garage tones, want to make your modern-day synth sound like 1972 or if you simply want to add a touch of vintage warmth and presence to your guitar/bass/vocals/whatever, then the Jive - Reel Saturator is your sonic dream come true.

139,00 €

  • Fast Shipping!1

Controls and Features

The Jive’s control set is supremely simple, yet staggeringly versatile. Familiar Volume and Gain controls make things louder and dirtier as expected, but what truly gives the Jive character is its three clipping diode toggles on the right-hand-side of the pedal.

The top toggle introduces an asymmetrical 1N4001 Silicon diode, the middle inserts a symmetrical 1N4001 Silicon diode, while the bottom toggle presents a symmetrical 1N5819 diode. Each option overrides the one above it so when the bottom diode switch is engaged, you are at the most extreme setting.

Use Jive as a volume boost, a subtle compressor or even a semi-transparent overdrive, exalt your sound with variable distortion or tear some walls down with lots and LOTS of dB. It is all up to you.

You can even run this mojo monster on everything from 9v to 18v giving you even more headroom to explore the crackling and gritty textures within the Jive.



 Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 6,5 x 13 x 6 cm with knobs

- Power requirement: 9-18 V DC PSU (centre negative, 2.1 mm)

- Current draw: <50 mA 


Please notice

If you engage the clipping diodes, the signal might get quieter because of added compression. Feel free to adjust the Volume according to your desired output level.

SUPER WEIRDO



Super Weirdo - Fuzz Modulator Pedal

 

A testament to its name, the Super Weirdo is unearthly, alien and downright trippy and besides that, it might be the only pedal that builds monumental walls, all while tearing them apart at the same time!

 

On the surface, the Super Weirdo is disguised as an early '90s style gated fuzz, with a dedicated low pass filter knob to effortlessly find your place anywhere in the mix. But that's far from where the freak show ends! This three-headed beast delivers fuzz, time modulation AND momentary glitch-bombs all in one enclosure.

179,00 €

  • Fast Shipping!1

Controls and Features

The core operation of this unit is to further enhance the input signal with an advanced, time-based modulation effect - The Pulse Width Modulator. Two dedicated knobs allow the player to multiply and manipulate their playing. The Feedback Mix controls the amount of modulated signal added to the base sound, acting almost as a doubler. A further Time Amount knob controls the distance between each modulated pulse, enabling the addition and separation of layer upon layer, resulting in a wall of thick, dynamic and articulate fuzz. Plus, if you dial in a short time setting, you get a double tracking fuzz tone. 

Beyond this, an extra momentary footswitch gives the player expressive freedom to disrupt the signal with quick bursts of oscillation - aptly named Glitch. Plus, to guarantee all manner of expressive possibilities, an expression input allows you to connect a standard expression pedal for on the fly creativity.



Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 12 x 15 x 6,5 cm with knobs

- Power requirement: 9 V DC PSU (centre negative, 2.1 mm)

- Current draw: <50 mA


Please notice

To ensure optimal operation place this pedal before your buffer or tuner. Also, the Super Weirdo can produce some extremely strage, glitchy and totally crazy sounds. That's what this pedal is about.

ADD VIOLENCE




Add Violence - Planetary Disorder Unit

 

While noisy, buzzy and sizzling fuzz and distortion sounds and general sonic heresy are indeed our medium, our reputation has felt somewhat unjustified and incomplete thus far. As such, it was our duty to release the planetary disorder unit that is the JPTR FX Add Violence.

 

The Add Violence is a very assertive fuzz that will outperform any of its contemporaries that are aimed at guitar players alone. It will also harmonize well with about anything and everything you fancy plugging into it. As always: we would never judge.

179,00 €

  • Available
  • Fast Shipping!1

Controls and features

Named after one of our favourite EPs, the Add Violence is a forceful, recklessly loud and uncompromising Super Fuzz. It is our take on the Univox classic, but on a jet rocket in a tank.

The Add Violence comes equipped with Volume, Gain, diode switching and Tone controls. The latter produces a very wide sweep - from complete mid scoop to full mid hump. Volume and Gain set how loud the pedal is and how much fuzz it produces. Disabling the diode switch results in a wholly more aggressive gated fuzz, with a raw, compressed and mid focused character. The diodes also provide an increase in volume, making the fuzz feel nearly twice as big. Engaging the diodes adds singing sustain and a very organic, dynamic breakup. In addition to that a Clean Blend (located inside the pedal) helps to maintain and balance clarity and texture, as well as retaining the native character of that beyond of just guitars. Other internal features help to shape your sound even further than the aforementioned controls.

Its practical control parameters allow it to especially shine with low end pronounced instruments, such drum machines, synths and bass guitars.


Internal adjustment options

- An upper octave control, transforming the Add Violence into an octafuzz

- A Boost control of up to 16db - loud enough to blow out your continental neighbours' eardrums

- A Clean Blend to maintain and balance clarity and texture, and to retain the native character of that beyond of just guitars.



Technical specs

- Hand screen printed, diecast Aluminium enclosure

- Size: 6,5 x 13 x 6 cm with knobs

- Power requirement: 9 V DC PSU (centre negative, 2.1 mm)

- Current draw: <50 mA


Please notice

To experience the Add Violence at its full potential, we recommend using it into a clean(ish) amp above 50 W. It has a very broad bandwith which small amps might not be able to represent as well as bigger ones.
