Effects Pedal Kit - MOD® Kits, The Rattler Returns, Distortion
To celebrate the 10 year anniversary of 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.

Effects Pedal Kit - MOD® Kits, The Rock Bottom, Bass Fuzz
The Rock Bottom is a bass fuzz kit that gives you all of the sizzle you'd expect from a vintage fuzz without sacrificing those low frequencies. Use the blend pot to set your fuzz levels and dial in the volume to get that sound you need. This versatile pedal can be used for the sludgiest bass tones to the cleanest boost and everything in-between.

Snubber Kit - eliminate fuzz from amplifier
Snubber parts kit for circuits. Used to build a "snubber circuit" to remove unwanted high frequencies and high voltages resulting from output transformer ringing in a guitar amplifier, without the "brick wall" effect of using diodes.

Effects Pedal Kit - MOD® Kits, Erratic Clutch Deluxe
The 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 dwell control adds an extra flexibility, providing a full palette of sweet reverb sound. The effect pedal operates on a 9V battery. For a longer lasting option, a 9-volt adapter can be purchased separately. The Godlyke 9-volt adapter (M-PAS-S) may be purchased separately to power your new pedal.
