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.

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.
$64.95
K-997 Effects Pedal Kit - MOD® Kits, The 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-996 Effects Pedal Kit - MOD® Kits, The Penetrator, Treble Boost
The 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.
$38.95
K-991 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.

K-978 Effects Pedal Kit - MOD® Kits, The Step Ladder, Input Attenuator
The 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.

These special features include a three position progressive toggle switch for off-standby-power and additional push-pull functionality for each control - pull out the bass control knob for “mid boost”, pull out the treble control knob for “bright”, pull out the volume control knob for “turbo”.
$265.00
K-965 Effects Pedal Kit - MOD® Kits, The Contortionist II, Fuzz
The 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.

K-MOD103 Effects Kit - MOD® Kits, The Wave, Spring Reverb
The Wave is a versatile stand-alone, tube driven analog spring reverb unit kit. It can be used in front of your guitar amp or as a line-level analog reverb effect for the recording studio. Two controls allow you to serve up a wide range of wetness from just a touch to over the top psychedelia. The "dwell" control adjusts the input signal level driving the tank and the "reverb" control adjusts the level of output reverberations from the tank. The Wave's all tube design utilizes four dual triode vacuum tubes - three 12AX7s and one 12AT7 - and comes with a MOD® three-spring reverb tank. MOD® reverb tanks are deemed the closest to the original reverb tanks from the '60s made today. The Wave's reverb function can be switched in and out pop-free via the front panel toggle or with a footswitch. Footswitch sold separately (see P-H470 for compatible footswitch).
$275.00
K-995 Effects Pedal Kit - MOD® Kits, The Aggressor, Distortion
The Aggressor is a high gain distortion pedal kit that delivers contemporary distortion with plenty of chunk and ear-splitting pitch harmonics.

The Aggressor features true bypass, LED indicator, and a versatile tone control with a scoop/bump switch that shifts the mid-frequency response allowing you to craft a tone that fits your style of playing. It works well with humbuckers and single coil pickups, so you can turn any guitar into a lethal weapon capable of inflicting serious brain damage and spontaneous combustion! MOD® Kits are designed to give 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. A pre-drilled enclosure and all necessary parts are included.

Swap to create a wide range of tones from just a hint of break up from the JJ 5751 to over the top crunchy distortion using the NOS US made 12AT7. 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.
