  • One Control Japonism Edition Purple Plexifier Distortion Pedal

    Our original Purple Plexifier Distortion was the first pedal we have made as an “amp-in-the-box” style of pedal. The brand-new Purple PLEXIDIST is the latest version of this circuit that modernly brushes up the tone of the original with brand new art and updated tone.

    What is the Purple Plexidist? This style of distortion is a classic that transcends time and will always be loved by guitarists. A tone that is vintage, classic, and a standard. Legendary tone that forms the foundation of the rock genre. And since we have put it into a pedal form, it is easy to carry and use anywhere, without troublesome maintenance or weight.

    With our new One Control PPD, you can make that tone simple and easy. The word “Plexi” simply means a transparent board made of acrylic. How did it become to be applied to rock guitar sounds? The classic British-made amplifier that most guitarists love had a control panel made of plexiglass (acrylic plate) made around 1969 and used by some of the most famous guitarists of the 1970s until the modern day.

    Back in 1962, the PA systems were very underpowered and usually only used for vocals. Guitar amplifiers were made to be powerful for a larger sound to keep up with the band. These guitarists helped to create the sound of rock, and top guitarists from all over the world have demonstrated the power onstage of this sound. Even today, many famous guitarists record and tour with their precious “plexi” amps to have this sound, so the legend of this amp continues to have an overwhelming presence.

    When guitarists refer to the “plexiamp”, there are many variations in the tone due to the output, combo, speaker choices, and the various model differences. However, this tone is indeed the sound as played by some of the masters of rock guitar. Our Purple Plexifier aimed for that tone, the gorgeous plexi sound with some “hot rod mods” like were done by amp technicians in LA during the Sunset Strip era. The famous “brown sound” was created during this era and is still desired by guitarists all over the world – with our Purple Plexidist you can have “that sound”.

    The most important thing in reproducing the plexi sound is not just the distortion – it’s meaningless to just simply distort the sound. Even at full-gain settings, if you play hard the sound will distort a lot, and if you play softer it will be clearer with just that “edge” of distortion. With the playing dynamics from just your fingers, you can control the strength of the distortion easily as well as have the articulation and details from the cleaner part of the sound. With our Purple Plexidist, you can have that same response, clean and distortion balance, and high-end details as the famous guitar amplifier.

    Bjorn's Description:

    The Purple Plexidist by One Control is our first Amp-In-A-Box (AIAB) design. The goal was to reproduce the classic sound of that iconic late sixties amp that has a similar name.

    The Purple Plexidist combines a gain range of +6db - +67db - a rare high dynamic range and a low dynamic range that is comparable to the best tube amplifiers. The tight bottom end with bright (but not harsh) highs will amaze you. Moreover, the thick mid-range, which can be scooped or flattened with the MID control, will give you fuller tone. Use this pedal to create a three-dimensional distortion by itself or use it in conjunction with the amp’s own distortion settings to create your own sound.

    The true test of any distortion effect is its ability to react to any playing style and intensity. The Purple Plexidist rewards the guitarist with a feel that is rare and responsive, no matter the type of pickups. The stretchable distortion patterns that follow the musicians playing dynamics separates this compact pedal from any other on the market. Even though this pedal was designed with a specific shade of distortion in mind, it lends itself to as many styles as the musician can explore!

    Purple Plexifier (PP) is a British AIAB (amp in a box) that creates the sound of rock that will last forever. It's a sound that any generation can play and enjoy. If you use it in combination with other distortion devices, the usage will be greatly expanded.

    I combine it with SROD and LLYC and use PP as a distortion box.
