EFC Heathkit Precision

For your consideration. A vintage Heathkit Precision vacuum tube volt meter converted into an Electron Fuzz Custom pedal. This is the standard pedal version. Quite aggressive. A serial numbered ID tag is mounted on the right side indicating it is an authentic member of the RMLfx family.

Two jumbo toggles have been added. One to switch to the x1000 screaming distortion (left side), the other works as a bypass (right side). Another jumbo LED glows to indicate power is connected. The two fancy knobs are the “Hurt” and “Pain” controls. The two lower knobs are the volume and the “Feedback noise”. I will include an card that defines the functions.

This is intended to be a studio piece and is not “Stompable”. But it can sit comfortably on a table for alternative styles table top performances and live in your studio as a secret weapon.

The knobs are all original. In the center is a new toggle switch for the low cut. The meter has a good response and at full volume hovers around the zero’ed center.

Size is about 8″x5″x5″ accounting for the handle and the bezeled meter face.

This light military green vintage box with original knobs and glowing jewel garnered to turn some heads and invoke questions about what it is. As always we do our best to keep the original form without drilling a bunch of holes and ruining the classic feel. While the patina of this box shows its age the unit has been cleaned and restored to the best of our abilities.

This unit is designed to ether sit upright or lay on its back.

In/Outs and power (9volts negative tip) are on the left side of the box. Print is laser etched.

More about the Electron Fuzz Custom Pedal:

The Electron Fuzz “Custom” is an extremely high gain distortion. Seriously, normal volume setting is at about 10% of its full output potential. Two gain/tone controls “Hurt” and “Pain” give a variety of tone textures and a feedback noise loop can be adjusted to add a very gritty almost 8-bit sound or a squelching scream. (Great for droning or well crafted solos and recording). The extra stomp switch adds 2 more additional gain stages and a boost of high end to the sound. Best of all the distortion oscillates when notes are held adding a new level of expression.

Here is a great demo video from the “Pedal and Effects” youtube channel featuring Alessandro Cortini of NIN, Sonoio and Modwheelmood.

[list_circle]Things I personally enjoy about this pedal:

  • Fuzzy to crunchy tones
  • Wide range of possible textures and character
  • Expressive distortion oscillations
  • Feedback noise loop for unusual sound design
  • Extremely high gain for recording direct to your DAW
  • Use with guitars and keyboards
  • VU meter responds to your playing


The red LED on the radio tower switches on when boost mode is enabled. A convent way to know where you are when playing.

• Knob controls:

A unique approach to tone control…

Hurt: Controls the gain of 3rd gain stage. Lowering the gain will also reduce low end.
Pain: Controls the gain of the 2nd transistor gain stage. Lowering the gain will reduce high end.
Output: Volume/saturation. Take some of the edge off the mix or crank the pain and hurt all the way for a big, dirty, crunchy fuzz.
FB Noise: On/Off adjusts the amount of feedback in the circuit for noise making. Creates a weird octave mod fx.

• Switch controls:
Low cut toggle: Cuts the low end for a slightly less bassy more gated sound.
x1000 gain: On left stomp switch. This takes your sound through an addition 2 transistor gain stages and pushes the electrons way past 11! The booster switch adds a loud and dirty, thrash crunch to this versatile pedal. Incredible for feedback noise and FX textures. Can cause the parasitic frequency oscillation but sounds awesome while playing.
True Bypass: Lets you play through the pedal.

• Meter: Responds to your playing, and reflects first gain stage transistor distortion. Illuminates when active.
