If you think boost pedals are kind of boring, the Crazy Tube Circuits Super Conductor is here to make you change your mind. This fully analog pedal delivers four flavors of boost, each inspired by established circuits producing different sonic characters.
The big knob on the top deals with setting the amount of boost, while a rotary knob in the middle of the case selects among the following modes:
- rm: a silicon reinterpretation of the ’60s classic germanium, Rangemaster-inspired treble booster using a unique setup with 2 low gain silicon transistors.
- ep: a colored JFET preamp – gain stage voiced after the preamp circuit of the Echoplex, operating at 24V DC via an internal voltage boost. .
- ma: based on a clean and “transparent” volume booster of the late ’70s / early ’80s (read: MXR Micro Amp-style), handy to run long signal chains with its low output impedance or drive your amp harder into natural saturation.
- mf: based on a late ’90s ultra-transparent, high input impedance MOSFET boost of the ZVex Super Hard On pedal, famous for its pristine highs.
Each mode can then be tweaked via two pushbuttons, one for a “fatter” sound with more low-end emphasis and one that changes the circuit’s voltage from 9v to 18v, for extra headroom. These modifications are tailored to each mode.
Here are the first videos of the Crazy Tube Circuits Super Conductor, we added it to our article about the best Rangemaster-inspired pedals (although it does a lot more than that!).
Crazy Tube Circuits Super Conductor, Builder’s Notes
Featuring 4 distinct boost circuits, based on one-knob-wonders of the present and past, these tone
accelerators can drive your rig into sonic bliss.Each all-analog circuit features different input/output impedance, voltage supply and behaves
differently on the volume / output knob, producing its own sonic signature, so that you can find the
one that suits your rig and playing style.We have added tone shaping modifications, individual to each circuit, that you can switch at will via
the white and black button modifiers.rm: our own silicon interpretation of the 60s classic germanium treble booster. Using a unique setup
of paralleling 2 low gain silicon transistors we’ve managed to produce a sound that will convince
even a NOS OC44 enthusiast.
Select between original voicing or enhanced lo-mid frequencies for fatter sound.ep: JFET preamp – gain stage based on the preamp circuit of a tape echo unit of the early 70s run on
true to the original specs 24V DC power supply via an internal voltage boost. This tone enhancer is
known for its magical coloration and the added focus and detail it gives to your sound.
Select between original 70s voicing or enhanced full frequency boost with extra output.ma: based on a clean and “transparent” volume booster of the late 70s / early 80s. This circuit is a
“reference” to louder solos. Use it to run long signal chains with its low output impedance or drive
your amp harder into natural saturation.
Select between original 9V DC power supply or internally boosted 18V DC for increased headroom.mf: based on a late 90s ultra-transparent, high input impedance MOSFET boost. This interpretation
doesn’t crackle but still retains the massive clean boost with pristine highs, sonic identity of the
circuit it was modelled after.
Select between original 9V DC power supply or internally boosted 18V DC for increased headroom.
