K-955 Effects Pedal Kit - MOD® Kits, The Thunderdrive Deluxe, 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 pre-amp 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.
This is an easy build kit with point to point wiring and clear, easy to follow instructions.

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).

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.
