The Unobtanium RAW is a dual overdrive pedal an all-analogue faithful reproduction of the legendary Klon Centaur overdrive voicing on the right, and two unobtainable tube amplifier voicings on the left.

Key Features

  • Legendary Tone – The faithful K-style tone that comes from this pedal is designed to inspire.
  • Pure Dumble Overdrive – With the help of the ‘60s NOS Mullard/Valvo OC45 Germanium Transistors, you can be sure that this pedal delivers authentic Dumble!
  • Passive Effects Loop – The passive effects loop gives you the option to connect your beloved pedals between your booster/overdrive and amp in a box or use the two sections as separate and independent effects when using an external bypass switcher/looper.
  • Power Up Bypass/Engage – This is a preset function for footswitches. That way you can select which state your pedal will go to when you plug in the power supply.
  • True Bypass/Buffered – Buffered or True Bypass Operation means you can fit this pedal in your signal chain easily.

K-Style

On the K-style side of the pedal, Crazy Tube Circuits has added an authentic voicing to the clipping section. This is a set of hand-selected Mullard/Valvo labelled OC45 germanium transistors from the ‘60s. This adds a supernatural feel with organic compression for increased gain and sustain. This is the first Klon-type circuit to feature germanium transistors in its clipping section!

Dumble Overdrive

The amp-in-a-box side of the RAW version is 2 Dumble voiced overdrive circuits and is glassier and punchier than the standard version of this pedal. Think of singing blues rock and classic rock sounds that cut through the mix, flawlessly performing with all kinds of different guitar/pickup combinations.

Specifications

  • Controls: gain, treble (tone), volume, bypass mode and clipping/compression.
  • Wide gain range control: from transparent boost to high headroom overdrive.
  • Treble control is an active circuit to boost or cut treble.
  • Volume knob sets overall output. Huge amount of dB boost available.
  • Select between the original buffer bypass to add clarity and run long cables or true bypass.
  • Select between stock clipping (germanium diodes) or enhanced compression, gain and sustain (NOS Mullard/Valvo OC45 germanium transistors).
  • Left side: Dumble amp in a box overdrive.
  • Controls: gain, emphasis, tone, volume, amplifier voicing toggle.
  • Gain control: from clean boost to raw singing overdrive.
  • Emphasis is a pre-drive EQ to control presence and bottom end response.
  • Tone controls the amount of post overdrive high end frequencies.
  • Volume knob sets overall output. Match bypassed volume or use as a clean boost or preamp.
  • Toggle switch selects between 2 distinct overdrive circuits voiced after Steel String Singer and Overdrive Special Dumble amplifiers.
  • SSS: “clean” overdrive with natural organic compression.
  • ODS: higher gain overdrive with enhanced mid frequencies and blooming harmonic overtones.
  • Left LED changes colour to half red when ODS voicing is selected.
  • External footswitch input to select between amplifier voicings.
  • External footswitch (XT) offered as an extra accessory (not included).
  • Internal trimmers adjust EQ and volume boost of overdrive voicings.
  • Passive series effects loop to connect pedals between the two sections or use them separately as independent effects.
  • Runs internally at 18V DC for higher headroom, tube-like performance and exceptional pick attack response.
  • Top-mounted jacks.
  • Click-less True Bypass design via high-quality relay.
  • Power-up bypass/engage preset function for the footswitches.
  • Power Supply: Use only 9V DC, center negative power supply (not included).
  • Current consumption 83mA.
  • Product box dimensions: (W x L x H) : 147 x 103 x 65 mm.
  • Product box weight 521g.
  • Sparkling quartz grey die-cast enclosure with white ink in old-school type print.
  • Made in Greece

Crazy Tube Circuits

In the current JustPedals catalogue, Crazy Tube Circuits is represented by Overdrive Pedals, Tremolo & Vibrato Pedals and Multi-Effects Pedals. Current listings include Mirage JR Reverb, Time Digital Delay and Unobtanium Dual Overdrive. That makes the range relevant to players looking for drive, gain and clipping, plus time-based effects and ambience. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.

Overdrive Pedals

Overdrive uses soft or moderate clipping to add harmonics and compression while retaining more of the original note shape than heavy distortion. Some circuits emphasise the midrange and trim bass before clipping; others remain broad, transparent or amplifier-like. Gain, clipping arrangement, headroom and tone filtering decide whether it supplies a light edge, a saturated drive sound or extra push into another gain stage.

Tags

Analogue

The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.

Presets

Stores complete groups of parameter values for later recall. The number of locations, switching time, spillover behaviour and whether presets include routing, expression and MIDI assignments determine how completely one sound can change into another.

True Bypass

Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
