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).

K-MOD102 Amp Kit - MOD® Kits, MOD102 guitar amplifier
The MOD 102 is a great place to start for those interested in building their own tube amp. It is based on a classic American tube-circuit design combined with a British style Class A output tube section. At low volume it produces a clean chimey tone that moves into smooth overdrive at higher volumes. All parts are included along with a pre-drilled steel chassis, wire and tubes (1 EL84 and 1 12AX7). Puts out at least 5 watts. The chassis layout is open for easy assembly using the clear, easy to follow instructions.

M-OD9 Effects Pedal - Maxon, OD9, Overdrive
Improved circuitry featuring the JRC4558 IC yields the ultra-smooth, creamy, dynamic overdrive so sought after by guitarists.
Overdrive and output level controls adjust the intensity of overdrive and output volume, while the Hi Boost/Hi Cut Tone control adjusts the brightness from warm and smooth to sizzling hot.
While the M-OD808 may have been the first overdrive circuit of its kind, it was the OD-9 that cemented this sound in the history of Rock & Roll guitar. Looking at the OD-9's circuit, you'll realize that this is not some redesign being cleverly marketed as a reissue – this is THE original OD-9 (TS-9) circuit, yet with the addition of true bypass switching.

M-OD808 Effects Pedal - Maxon, OD808, Overdrive
The Original Overdrive! The OD808 is often imitated but never matched! Identical to the 1970s circuit and featuring the JRC4558 IC chip, it offers warm, smooth, transparent overdrive that'll make your rig scream! The OD808's dynamically responsive circuitry reacts precisely to individual playing styles, letting the true voice of any instrument or artist shine through. Don't settle for copies when you can have the original. The OD808 Reissue offers up all the warm, creamy, organic overdrive as the original and then some. Never one to rest on their laurels, Maxon has tweaked the current version ever so slightly to reduce noise level while retaining the legendary “808" tone. The OD808 is the perfect pedal for adding smooth, tube-like overdrive to any clean amp – use it as a secondary dirt channel to beef up a song's chorus section, or keep it on all the time for the crunchy tone that has defined rock and roll.

K-997 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.
