Pedal Kit - Mod® Electronics, Erratic Clutch Deluxe
The Mod® Electronics Erratic Clutch Deluxe is a unique effect pedal kit that gives you fuzzy square wave distortion as well as a monophonic sub-octave square wave using a total of only four transistors. The two signals can be used individually or mixed together for a raw and sonically rich synthy output. Full of character and quirk, this pedal will give you a truly original sound. The middle knob is the bias control. This adjusts the pulse width in the initial fuzz stage of the pedal. Set this knob to fit your pickups and playing style. The closer to the center the longer the note will sustain but with that comes more chaotic tracking for the divider. Moving it more clockwise or counterclockwise will give you more predictable note tracking on the divider with less sustain.

Pedal Kit - Mod® Electronics, Phase / Off, Modulation - Phaser
The Phase / Off is a four-stage phaser based around the Sound Semiconductor SSI2140 voltage-controlled multi-mode filter. This pedal offers classic phasing effects along with plenty of control to dial in the perfect amount of modulation using the Depth, Rate, and Regen knobs. The Stages switch can change the Phase / Off from four-stage phaser to a two-stage phaser providing a wide variety of different phasing sounds. Change the Mode switch from LFO to Manual to use the Phase / Off in fixed phase mode controlled by the Depth knob for unique filtering effects. The Phase / Off pedal kit is the second entry in the Nexus Series from Mod® Electronics. This series features a PCB base rather than the Mod® Electronics’ traditional point-to-point wiring kits to offer builders an even wider variety of effects to build. The Phase / Off is a great pedal for intermediate skill sets. It features an all through-hole build with pre-soldered SMT SSI2140. The pedal operates on 9VDC.

Pedal Kit - Mod® Electronics, Seismic / Shift, JFET Boost
The Seismic / Shift is a JFET boost based on one of the earliest effects to ever be used on stage. This pedal adds subtle color to a guitar's sound while maintaining the natural tone of the guitar. It packs a serious punch that can cut through any mix when soloing or whenever some extra “umph” is required. The Seismic Shift pairs nicely with amps and other pedals. Place it ahead of tubes, preamps, overdrives, distortions, and fuzz pedals to shift your gear onto a new level. The Seismic Shift pedal kit is the introduction to the Nexus Series from Mod Electronics. This series features a PCB base rather than the Mod Electronics’ traditional point-to-point wiring kits to offer builders an even wider variety of effects to build. The Seismic Shift kit is designed for all skill sets and is the perfect first build for those unfamiliar with PCB construction. The pedal operates on both 9VDC and 18VDC.

Pedal Kit - Mod® Electronics, Step Ladder, Input Attenuator
The Mod® Electronics Step Ladder is a passive input attenuator using high quality components for excellent reliability. True-bypass mode provides the maximum signal level. The attenuator pot and two toggle switches allow for flexibility in the amount of signal attenuation when not in bypass mode. Treble bleed capacitors in the circuit retain crisp high frequencies even at maximum attenuation. The Step Ladder is ideal for anything from getting a slight boost while playing single-note acoustic guitar leads or for jumping from clean to overdrive in a high-gain electric guitar amp.

Pedal Kit - Mod® Electronics, Suspended Chime, Chorus, Delay
The Mod® Electronics Suspended Chime has two powerful effects in one pedal - chorus and chorus/delay. The Suspended Chime features a blend knob which allows you to go from subtle to lush chorus effect in either set up. Using the toggle switch, you can add a 190 millisecond delay to the chorus introducing special depth to your tone. Varying the dry/wet mix can fatten your rhythms or produce a shimmering 12-string sound. The Suspended Chime kit comes equipped with an LED indicator and industry standard 9 volt center negative power jack. MOD® Kits are designed to give both novice and experienced musicians the opportunity to build their own amps and effects pedals. All kits come with easy to follow instructions and use point to point wiring. Pre-drilled enclosure and all parts are included. All you need to provide are hand tools, a soldering iron and solder. All effects pedals operate on a 9V battery.

Pedal Kit - Mod® Electronics, The Contortionist II, Fuzz
The Mod® Electronics Contortionist II kit is an all analog, high octane fuzz box. It produces fuzz with layered octave overtones similar to those produced by an electronic-bow. The frequency multiplier circuitry creates harmonics that swell and recede depending on gain setting, pick attack, neck position and pickup. This is a high gain circuit that can put out up to 2 volts and will provide ample amounts of sustain. The Contortionist II has all the features of the original Contortionist with an added tone control for a wider range of sounds, and an LED that lights up when the unit is activated.

Pedal Kit - Mod® Electronics, The Penetrator, Treble Boost
The Mod® Electronics Penetrator is a treble boost pedal kit with enough gain to cut straight through any mix. This pedal adds glistening harmonics that get loud enough to saturate your amp’s front end. Adjust the level knob to vary the output so there’s no mistaking when you kick this pedal in. Great for solos or when you need your guitar front and center.

Pedal Kit - Mod® Electronics, The Persuader Deluxe, Overdrive
The Mod® Electronics Persuader Deluxe utilizes a Darlington preamp to push cascaded triode vacuum tubes into distortion. A boost switch provides an additional layer of flexibility with added gain and a little extra bottom end. An LED indicator lights up when the Persuader Deluxe is engaged and not in true bypass mode. Operates on a 9V battery or AC adapter, which is not included. When completed, this pedal draws considerable current and battery life will be short. The Godlyke 9-volt adapter (M-PAS-S) may be purchased separately to power your new pedal.

Pedal Kit - Mod® Electronics, The Rattler Returns, Distortion
To celebrate the 10 year anniversary of Mod® Electronics Mod® kits, we are re-releasing a new and improved version of the original Mod pedal - The Rattler. This fan favorite is making its long-awaited comeback as The Rattler Returns. The Rattler Returns offers the same over-the-top fuzz as the original Rattler and features several new upgrades. The circuit has been overhauled for a wider spectrum of fuzz that is steady when used with any pickups, pedals, or amps. The Rattler Returns preserves the diode clipping, a crucial component of the classic raw fuzz/distortion in the original but also features a diode lift switch. With the lift engaged, the pedal can hit volumes that easily drive any tube or pedal with fuzzed out guitar tones. The pedal now operates on +9V, so standard DC power supplies can be used in lieu of a battery if you choose.

Pedal Kit - Mod® Electronics, The Ring In Return, Octave-Up Fuzz
The Ring In Return is an octave-up fuzz effect that is an all-analog design that captures those late 60s octave-up fuzz tones. Transformer-coupled germanium diodes produce sounds that range from a subtle octave-up to thick, harmonically-rich sonic textures and synth-like tones. Experimenting with different pickups and tone-control settings on your guitar with The Ring In Return can also produce sitar-like sounds. Warning: This circuit was designed for use with a 9 VDC power supply only.
