Pedals & Kits

This radio kit will cover the AM radio band along with the SW radio band. Power for this receiver is 1.5 V DC for the filaments and 45V DC for the plate current. A D cell and five 9V transistor batteries wired in series will work to power this radio. A 2000 ohm headset or an audio amplifier is required.
Requires two T-1T4_DF91 tubes (not included).

The Mod® Electronics Trill tremolo pedal offers classic tremolo tones in an easy to build kit. The Trill's speed knob provides a wide range from a very slow to rapid fire effect. The depth knob varies the ratio between effected and dry signal. Using modern, low noise transistors makes operation of The Trill quiet with no signal drop when engaged. The Trill uses true bypass foot switching so it is out of the signal path when not engaged. All you need to provide is solder and tools! Uses 9 volt battery which is not included.

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.

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.

The K-GMOD-6 is a vintage style wiring kit for ES-335 guitars. Use this kit to upgrade your current ES-335 electronics to high quality parts. This kit also includes a treble bleed mod for the volume pots to enhance clarity with lower settings and comes with detailed instructions and all the parts you need to make your modification.

The Maxon OD-9 is the original Tube Screamer TS9 circuit built by the company that designed this immensely popular overdrive pedal.

The OD-9 offers slightly more gain than the OD808.
Features

• Identical to the original circuit and featuring the JRC4558 IC chip
• Natural tube-like overdrive that smoothly responds to dynamic signals
• True Bypass Switching
• Low noise mechanical switch
• LED indicator for effect on/off
• DC power or 9V battery
• Made in Japan

Junior Genius Kits are built for experimentation, learning and fun! Experience the joy of seeing your first LED light up. The Blinky Lights Kit leads you through 10 core activities, from a simple LED circuit up to more advanced transistor LED blinky light circuits, using standard parts on a real-world breadboard. Learn about voltage and current by using LEDs, resistors, capacitors and transistors. You'll be able to build circuits using a schematic diagram, and there's plenty of help to get you there. Simple examples make it easy to grasp the basics and 'What's Happening' and 'Things To Try' sections encourage you to dig deeper. You will get valuable assembly and troubleshooting experience as you learn to use a great experimentation tool, the solderless breadboard. Real hands-on experience means greater educational value. This next-generation science kit doesn’t seal the parts into simplified plastic blocks.

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.
