Dual Overdrive With Two Independent Sections!

Unobtanium - a rare tone element derived from legendary sounds. A mythical overdrive meets the sound and character of two iconic amplifiers. Crazy Tube Circuits has precisely reproduced the circuit of the high-headroom overdrive with its magical blend of clean and distorted sounds and expanded it with additional features for greater versatility.

The amp section uses a fully analog circuit to deliver the character of two legendary D-style amplifiers — from tube-like, compressed, fat cleans to singing overdrive with radiant harmonic overtones. Combine both sides for an almost endless, smooth sustain and experience pure sonic bliss. A passive, serial effects loop allows you to insert your favorite pedals between the overdrive and amp sections so you can assemble your ideal setup.

Features

  • "Klon" (pedal) and "Dumble" (amp) together in one unit - ultra-rare tone elements that are normally unobtainable
  • "Klon" pedal channel (right side) - authentic reproduction of the original circuit
  • "Dumble" amp channel (left side) - 2 overdrive circuits with Dumble voicings (Steel String Singer / Overdrive Special)
  • The Klon and Dumble channels can be used independently or in series.
  • Switch between the two Dumble amp characters using the onboard switch or an external footswitch (available as an accessory)
  • Passive, serial effects loop for inserting pedals between the two sections or to use as independent effects
  • Two legendary tone elements combined in one unit
  • Right side: Overdrive circuit in "K-Style" with the famous germanium diodes
    - Controls: Gain, Treble (Tone), Volume, Bypass mode and Clipping / Compression
    - Wide gain range from transparent boost to high-headroom overdrive
    - Treble control: active circuit to boost or cut the high frequencies
    - Volume control: controls the overall output level, providing plenty of dB boost
    - Switch to toggle between the original buffered bypass (for more transparency and long cable runs) or True Bypass
    - Switch to toggle between the original clipping/compression behavior or extended gain and headroom
  • Left side: "Amp in a box" with "D-Style Overdrive"
    - Controls: Gain, Emphasis, Tone, Volume, switch for the amp character
    - Gain control: from clean boost to singing overdrive
    - Emphasis control: pre-overdrive EQ to control presence and low-end response
    - Tone control: adjusts the intensity of the high frequencies after the overdrive
    - Volume control: controls the overall output level to match bypass volume or to use as a clean boost or preamp
    - Switch to select between two independent overdrive circuits
    - SSS: cleaner and more transparent overdrive with natural, organic compression
    - ODS: overdrive with more gain and emphasis on mid frequencies and harmonic overtones
    - Connection for external footswitch to change amp character (disables the onboard switch)
    - Trim pots inside the enclosure to adjust EQ and volume-boost of the overdrive voicings
  • Passive, serial effects loop for inserting other pedals between the two sections or to use as independent effects
  • Internally runs on 18 V DC for more headroom and tube-like behavior
  • Outstanding response to pick attack - almost endless, smooth sustain when both sides are used together
  • Top-mounted jacks
  • Silent True-Bypass design with high-quality relay
  • Power supply: 9 V DC only, center negative (power supply not included)
  • Current draw: 83 mA
  • Pebble-gray die-cast enclosure with black retro-style lettering
  • Made in Greece
