Effect Modules by Lee Jackson

These are the next evolution of our miniaturized effects.
We took the best of what artists liked about our CrackPotz™ line and made the changes we where asked for.
Now with the new Lee Jackson Effects Modules these can fit in any sized instrument, from the thinnest Ibanez to a Gibson Les Paul. With the new design you can use any control pot and switch combination.
Built with the highest quality discrete components,
Right here in Austin Texas.

Works in any instrument.

These Effect Modules are an improvement from the Crackpotz line of effects. Now you are not restricted to the depth of your instrument and what configuration of Control Pot, or Switching you want to use, and where you want to put it on your instrument.
These new Modules are about the size of a quarter.

Active Guitars

The Effects Modules also work great with Active Guitars.
You can wire them directly to the battery that is powering your Active Pickups. Don’t let the size fool you, these have the same great sound as our full size pedals.

You can also put these in a small effects box and use them as a pedal.

Active Gain Booster

Lee developed the Active Gain™ Booster with a circuit that doesn’t degrade the original sound; it enhances it with more clarity and definition. This allows you to truly make your instrument go to 11 and higher. Pushing the amp to really make it sing. Or make your Acoustic stand out over the rest. Plus it can be wired TRUE BYPASS.
The Most Awesome Gain Booster you have ever heard..
Keep your Tone… Just have a lot More of it!

True Bypass

Can be wired True Bypass or Buffered Output.
This is the same Design and Circuit as the CrackPotz™ BitchBoost™ and Active Gain Pedal.


The “CreamyCompressor™” does not change the tone of your instrument. Most Compressor’s change the sound of the instrument for the sake of the compressor. The Creamy Compressor™ allows the full frequency of your instrument to pass through, this is why it sounds more like Studio Compression. It is the Warmest, smoothest compression you have ever heard. The Peak Reduction and Expansion controls the amount of Compression and Expansion, which causes the circuit to be more sensitive to your playing style.

Variable Compression

Between how high you have this control and the level of your guitar.
You can dial in the amount of compression you want, and when you want it to come on. As you turn it toward expansion, it will increase the gain and hold the notes longer, for sustained chords or solo notes.
The only OnBoard Compressor that sounds like a Studio Tube Compressor, with all the Warmth and Tone!


Vintage Studio Compression Sound.
Peak Reduction and Expansion Ability.
Sensitive to your playing style.
Can be wired True Bypass.
100% Discrete Analog Circuitry

Mr Fuzzzy™ Fuzz

The first thing I thought when I played Mr Fuzzzy™ was, man it is fun to play guitar. For years I have been working on a design to allow you to have your favorite Vintage Fuzz Sound. I have developed a circuit that doesn’t degrade the original sound. It can Clean up to a Sparkling Clean Sound by turning the volume of your guitar down. Mr Fuzzzy™ will enhance your great Rhythm sound without dropping out all your Low End. Get ready for Chocolatey Luscious Solo’s, and Endless Possibilities. Oh Yeah and for the Good part.
Mr Fuzzzy™ is completely discrete NOS Germanium and Silicon Transistors, it can be wired True Bypass. Mr Fuzzzy™ is Hand Made with the Finest components.


Smooth and Rich Sounding NOS Germanium Fuzz.
Accommodates Different Styles and Guitars and Basses.
Can be wired True Bypass.
Same circuit as our our Famous FuzzyFinger™ Pedal.

BCR Booster

This is the exact booster that Lee hand made for BC Rich Guitars in the late 70’s. Lee worked for BC Rich in the late 70’s wiring their guitars and making their boosters and varitones.
You now can get one for your Old BC Rich or if you want to put one in your new guitar. This booster is built with transistors instead of op amps and has a warm distortion when pushed.
