Summary Written by Dave Zimmerman - Maven Peal Amplifiers
The "Snubber" circuit was published in the "Radiotron Designers Handbook" in the 1930s and is supposed to serve as a "[sonically transparent] shock absorber" to remove unwanted high frequencies and dangerously high voltages resulting from output transformer ringing, without the "brick wall" effect of using diodes.  "Output transformer ringing oft

This kit was designed for the guitarist who owns a silver-face Bassman and rarely uses the bass instrument channel. Turn the bass instrument channel into a foot-switchable vintage tremolo effect for the normal channel. The kit comes with parts and easy to follow instructions. You will need your own tools and solder

This kit is for the guitarist who owns a vintage Fender amp that uses two 6L6GC's and wants to be able to use EL34 tubes in their place. The kit comes with electronic components, two EL34 vacuum tubes and easy to follow instructions. You will need your own tools and solder.

This kit is for those guitarists who want to experiment with spicing up the tone of their vintage silver-face or black-face Fender amp by modifying the tone stack components. The kits comes with parts and easy to follow instructions. You will need your own tools and solder.

The Suspended Chime has two powerful effects in one pedal - chorus and chorus/delay. The Suspended Chime features a blend knob which allows you to go from subtle to lush chorus effect in either set up. Using the selector switch, you can add a 190 millisecond delay to the chorus introducing special depth to your tone. Varying the dry/wet mix can fatten your rhythms or produce a shimmering 12-string sound. The Suspended Chime kit comes equipped with an LED indicator and industry standard 9 volt center negative power jack. 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. All effects pedals operate on a 9V battery.

Clear sound of solid-state amp and soothing warm sound of tube amp - this company cubic amp enjoys the good aspects of those two different types of amplifiers. Deck your desk with this sophisticated amp and its pleasant sound.Features

• Hybrid of vacuum tube input buffer + D-class speaker amp (AB-class headphone amp built-in)
• DC-controlled electronic volume built-in the amplifier IC. Therefore the volume deflection between right and left channels at small sound volume is minimized.
• Headphone output
• Built-in USB-DAC for PC connection
• Interlocking the amp power ON/OFF with the PC USB power selectable
• Assembly kit for users to experience the fun of DIY (A PCB is preassembled, no soldering is required. For assembly, users will need a long-nose pliers and a screwdriver only. (A hex wrench is included.))

Junior Genius Kits are built for experimentation, learning and fun! Experience the joy of seeing your first LED light up. The Blinky Lights Kit leads you through 10 core activities, from a simple LED circuit up to more advanced transistor LED blinky light circuits, using standard parts on a real-world breadboard. Learn about voltage and current by using LEDs, resistors, capacitors and transistors. You'll be able to build circuits using a schematic diagram, and there's plenty of help to get you there. Simple examples make it easy to grasp the basics and 'What's Happening' and 'Things To Try' sections encourage you to dig deeper. You will get valuable assembly and troubleshooting experience as you learn to use a great experimentation tool, the solderless breadboard. Real hands-on experience means greater educational value. This next-generation science kit doesn’t seal the parts into simplified plastic blocks.

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.

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.

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.
