Lectric FX

The company's identity is vintage re-creation. Nearly every Lectric FX project is a printed circuit board version of a classic effect, usually one whose original parts are hard or impossible to find, with modern substitutes chosen so a builder can actually finish it. The range covers delay, phaser, fuzz, overdrive, boost and tremolo circuits¹²³.

What Lectric FX sells: PCBs for DIY pedal builders

Each Lectric FX product page is a PCB project. The boards are sold by version, and the pages carry the build document as a PDF download, plus in some cases a bill of materials with individual part numbers. The Downtown Fuzz/Octaver page, for example, links its build document and a BOM with individual part numbers available via Google Drive².

Several boards ship with a small extra that saves the builder wiring work: a complimentary mini 3PDT footswitch PCB, included with the Downtown² and with every Fuzz Tang board⁴. The footswitch PCB makes the offboard switching connections easier than wiring a 3PDT switch directly.

Delay PCBs based on the Memory Man and Echo 600

The Memento Delay is a re-creation of the very first Electro-Harmonix Memory Man delay pedal, which Lectric FX notes has no relation in design to the later Deluxe Memory Man¹. The original used three SAD1024 bucket brigade devices, which the maker describes as unobtainable, so the PCB substitutes a PT2399 delay chip¹. The Memento lists at $11.99, currently on sale at $9.00¹.

The DC-Echo V.1.0 is an analog delay PCB kit described as a faithful reproduction of the Electro-Harmonix Echo 600, an extremely rare pedal from the very early eighties⁹¹¹. Lectric FX characterizes its sound as a cleaner and brighter version of a Deluxe Memory Man⁹. It lists at $18.99, with the schematic available on the product page⁹.

The DC-Echo page also carries practical build notes: an audio probing flow for the wet signal in Long Mode listed at test points including IC1 Pin 1, IC7 Pin 7, TP2 (IC10), TP3 (IC11) and TP4 (IC12), and a warning that builds using a 3PDT PCB need a ground connection to the main board that is not shown in the document, while no 9V wire is needed since the LED is powered from the main board⁹.

Phaser PCBs based on the Small Stone

The phaser line is built around the Electro-Harmonix Small Stone family, with one board per version of the original³⁷¹²:

• SpaceHarp (V1.2): a 4-stage phaser based on the early EHX Small Stone v1, using 3 LM13700 OTA chips rather than the out-of-production CA3094s, with an internally switchable JFET-buffered input. $12.99. V1.2 repaired a PCB error at C8 and changed the color toggle to switch up and down rather than side to side³.
• SH2 (SpaceHarp V2): a 4-stage DIY phaser based on the EHX V2 Small Stone, which Lectric FX calls the version most players think of as the classic effect. It uses a different input stage, feedback network/color sound and LFO section than the V1 board. $12.99. The page notes a silkscreen error: the rear of the PCB reads 100KB for the rate pot but should read 1MC, as listed in the build doc⁷.
• SH3 (SpaceHarp V3): based on the Small Stone V3, a completely new design using the LM13600 OTA for the phase stages with an op amp oscillator and input and output stages. $12.99¹².

Two further phasers step outside the Small Stone family. The Bloodstone Phase Shifter is a DIY project compared to the vintage EHX Bad Stone Phaser, with true bypass switching, the auto/manual and phase/vibrato switches of the old unit, a clean boost on the output and two internal trimmers to set the volume of each mode¹³. The current version is V.1.2³; the V.1.1 board corrected the orientation of Q2¹³. The Altered State Phaser V.1.0 is Lectric FX's take on the Maestro PS1-A Phaser, shrunk to fit a 1590BB enclosure while keeping the internal +/-12V supply of the original. It comes with 3 daughter boards, one each for slow, medium and fast, and an included matched sextet of MMBF5485 JFETs pre-soldered to through-hole converters, priced from $14.99 to $29.99 across variants¹⁴¹⁵¹¹.

Fuzz and octave PCBs

The fuzz and octave boards again follow vintage circuits:

• Downtown Fuzz/Octaver V.1.0: a replica of the rare, long out-of-production EH-5950 Deluxe Octave Multiplexer (5 knob version) from the late 1970s. Lectric FX says it gives "a great crunchy, deep & rumbling analog tone, and produces synth like sounds"². $19.99, sale $15.99, with a complimentary mini 3PDT footswitch PCB².
• Fuzz Tang: a pedalboard-friendly PCB of the vintage Maestro MFZT-1 Fuzztain compressor/fuzz circuit, a MOSFET-based compressor running into an op amp distortion stage. Lectric FX describes it as "a more refined big muff, producing long sustained fuzz notes and chords"⁴. Three modes come on a rotary switch: Sustain (a straight compressor), Soft (compressor into soft clipping fuzz) and Hard (compressor into hard clipping fuzz), with input gain and output level controls⁴. $12.99, sale $11.99⁴.
• Pork Rind Fuzz Octave: a silicon transistor Superfuzz-style circuit with octave up. $10.00, sale $7.00⁸.
• Mongrel OD/Fuzz: an NPN transistor beaten into clipping by a hot signal from an op amp, with pre-gain and bias controls. $10.00, sale $7.00¹⁵.

Overdrive and boost PCBs

The BloozeHound Overdrive is a DIY overdrive PCB based on the Boss BD-2, without the Boss bypass switching⁵. The Heiss Wurst V.2.0 is a CMOS overdrive compared to the vintage Hot Tubes overdrive with some extra filtering, and includes a tone bypass switch; the V2 circuit is unchanged from V1 but has an improved layout, which the maker says results in much lower noise with the drive control dimed¹⁶. It lists at $9.99, currently $7.00, with both V.2.0 and V.1.0 build documents on the page¹⁶.

The Betty Boost is Lectric FX's version of the DOD FX-10 BI-FET clean boost, an op-amp clean booster with a tone control that also allows bass or treble boosting, adapted for true bypass⁶. It lists at $7.00, currently $4.99⁶.

Where the build documents live

Every product page links its own PDF. Confirmed document links include the Downtown build document², the BloozeHound document⁵, the Betty Boost document⁶, the Heiss Wurst V.2.0 and old V.1.0 documents²⁵⁶, the SH2 build document²⁵⁶ and the DisDis V.1.0 build documentation²⁵⁶. A builder reads the document before ordering parts, since it carries the BOM, the offboard wiring and any errata, such as the SH2 rate pot silkscreen correction⁷.
