Crackpotz are effects built into replacement tone knobs and include distortion, boost, compressor, wah, and fuzz.

Austin, TX (September 23, 2010) -- Famed amplifier guru, Lee Jackson, who founded the legendary Metaltronix & Lee Jackson Amplifier lines, has announced the introduction of the world’s first direct replacement tone knob effects, Crackpotz Effects, made in Austin, Texas.


From his early days modding and designing amps for artists like Paul Gilbert, Steve Vai, George Lynch, Allan Holdsworth, Scott Henderson, and Zakk Wylde, Lee has developed a line of effect pedals, some of which incorporate his famous amp designs. Now, Lee has taken many of his famous sound designs and incorporated them into replacement tone knobs for guitarist and bassists alike. Lee uses analog circuitry with true hardwire bypass on all Crackpotz replacement knobs.

Lee’s first Crackpotz, the Stack in a Jack, is modeled after his famous Marshall mods. Says Crackpotz, "It is the warmest, smoothest distortion you have ever heard. It really acts like one of Lee’s guitar amps as the distortion is fully controllable by your guitar!" Retail $149.

Next, Lee introduces the circuitry used in his Active Gain pedal in the Crackpotz BitchBoost. Crackpotz says, "This incredible model features a buffered output that when pulled on at unity gain (0), will allow you to run a 250ft guitar cable with zero signal degradation! Then, when dialed from 1 to 11, you can increase the output of your instrument by over 100 times its normal output, driving the front end of a tube amp to perform tones you never knew your amp could produce!" This model is popular with players like Victor Johnson from Sammy Hagar’s band. Retail $99.

Next, Lee offers the Creamy Compressor, a true analog studio-quality compressor and expander that brightens and sparkles. Says Crackpotz, "Guitars like Teles and Strats excel with this thrilling new replacement knob! Put a Creamy Compressor and a Stack In a Jack, into the two useless tone knobs of a Strat for the ultimate rock and rock machine!" Retail $129.

Next, Lee gives players the exciting Shock 'N' Awe Wha, custom-voiced with an authentic ‘60s Vox-type inductor for that sweet thick singing top end with full dynamic range. Says Crackpotz, "Players such as Jimi Hendrix, used their wah pedals as a frequency boost by turning them on and leaving them in a certain position for that extra edge. Get the same exciting edge at the pull of a switch, sweep the knob to your desired frequency, and get that classic tone!" Retail $139.

Finally, Lee offers a fuzz for guitar and bass, Mr. Fuzzzy. Using the same circuit as found in his famous Fuzzy Finger pedal, Lee gives players authentic vintage fuzz tones using original germanium transistors. Retail $149.

All of Lee’s Crackpotz effects can be used together, or individually, and mounted easily into most of today’s electric guitars and basses with a minor installation.

How Jeff Tweedy, Nels Cline, and Pat Sansone parlayed a songwriting hot streak, collective arrangements, live ensemble recording, and twangy tradition into the band’s new “American music album about America.”

Every artist who’s enjoyed some level of fame has had to deal with the parasocial effect—where audiences feel an overly intimate connection to an artist just from listening to their music. It can lead some listeners to believe they even have a personal relationship with the artist. I asked Jeff Tweedy what it feels like to be on the receiving end of that.

Luthier Maegen Wells recalls the moment she fell in love with the archtop and how it changed her world.

The archtop guitar is one of the greatest loves of my life, and over time it’s become clear that our tale is perhaps an unlikely one. I showed up late to the archtop party, and it took a while to realize our pairing was atypical. I had no idea that I had fallen head-over-heels in love with everything about what’s commonly perceived as a “jazz guitar.” No clue whatsoever. And, to be honest, I kind of miss those days. But one can only hear the question, “Why do you want to build jazz guitars if you don’t play jazz?” so many times before starting to wonder what the hell everyone’s talking about.

After many decades of sticking with flagship body shapes, Fender spent the last several years getting more playful via their Parallel Universe collection. The Meteora, however, is one of the more significant departures from those vintage profiles. The offset, more-angular profile was created by Fender designer Josh Hurst and first saw light of day as part of the Parallel Universe Collection in 2018. Since then, it has headed in both upscale and affordable directions within the Fender lineup—reaching the heights of master-built Custom Shop quality in the hands of Ron Thorn, and now in this much more egalitarian guise as the Player Plus Meteora HH.
