K-997 Effects Pedal Kit - MOD® Kits, Erratic Clutch Deluxe, Fuzz/Divider
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.
$69.95
K-998 Effects Pedal Kit - MOD® Kits, Tone Attack, Active Tone Stack
Shape your sound with the Tone Attack. 12 o'clock settings give an approximate unity gain with the pedal. Rotate the treble or bass knob counterclockwise to cut the corresponding frequencies. Rotate these same knobs clockwise to boost the frequency bands. The master boost knob can be used to attenuate your signal or push your tone to screaming loud volumes. 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. The Tone Attack operates on a 9V battery or AC adapter, which is not included. The Godlyke 9-volt adapter (M-PAS-S) may be purchased separately to power your new pedal.

K-956 Effects Pedal Kit - MOD® Kits, The Thunderdrive Deluxe LTD, Overdrive
The Thunderdrive Deluxe LTD is an overdrive pedal kit that will provide a strong clean signal boost in the early gain settings and smooth distortion at maximum gain settings. Adjusting output and distortion controls provides a wide variety of tones in spite of its simple construction. It is capable of overdriving the preamp section of your guitar amp or adding its own layer of distortion at lower volume. This version is equipped with a three position diode selector switch.
The switch offers three different settings and tones. The top position is the classic silicon clipping diodes used in the original Thunderdrive. The middle position gives you the lifted diode "turbo" sound from the Deluxe model. The bottom position is a new setting limited to this version using germanium diodes for a warm vintage distortion.
