Four legendary boost circuits, one powerful pedal.

The Super Conductor by Crazy Tube Circuits delivers four unique boost circuits, each inspired by classic one-knob boosters from different eras. Whether you need transparent gain, midrange push, or vintage treble enhancement, this pedal provides versatile tone shaping with switchable EQ modifications.

Key Features

• Four Boost Circuits – Select between:

  • RM – A silicon interpretation of the classic 60s Germanium treble booster, using two low-gain silicon transistors to replicate the presence and bite of vintage designs.

  • EP – A JFET preamp based on the preamp circuit of a 1970s tape echo unit, running at 24V DC internally for enhanced clarity and harmonic richness.

  • MA – An op-amp boost modeled after a late 70s/early 80s clean volume booster, ideal for running long signal chains or driving an amp into natural saturation.

  • MF – A MOSFET boost inspired by a late 90s ultra-transparent high-input impedance design, delivering massive clean boost with pristine highs.

• Switchable EQ Modifications – The white button modifier operates on RM and EP circuits, while the black button modifier affects MA and MF circuits, allowing individual tone shaping per circuit.

• Internal Voltage Handling – Each circuit has different input/output impedance and internal voltage, affecting how the volume/output knob behaves.

• True Bypass Switching – Maintains signal clarity when disengaged.
