The “Legends Of Fuzz” series is a collection of the world’s most historic, rare, and sought after circuits. 

At JHS, fuzz pedals have been in our lineup for over a decade. We have designed original circuits, replicated classics, and we have seen the trend of fuzz popularity come and go. The “Legends Of Fuzz” series is our tribute to the most important fuzz circuits ever made. It is our way of ensuring that the stories of these effects live on in the music that you are going to make. From the earliest days of fuzz in the mid-60’s London scene to the 1990’s ex-Soviet military factories that brought the Big Muff back to life, fuzz tells a story, and that story includes guitarists just like you. There is nothing more primitive than plugging your guitar into a vintage fuzz circuit; it is raw, untamed, and so pure that it pushes the boundaries of what your instrument can accomplish. Plug into a fuzz and plug into sixty years of beautifully broken sound. 

Kay Musical Instruments was founded by Henry “Kay” Kuhrmeyer on July 1, 1931. Although Henry quickly shifted production focus to all types of stringed instruments (including basses, violas and guitars), they didn’t enter the guitar pedal market until the late 1960s with a series of  knobless, treadle-based delightfully odd plastic pedals. Each of these four units (the Fuzz Tone F1, Tremolo T1, Wah Wah W1 and Bass Boost B1) were housed in knobless, treadle-based enclosures allowing one parameter of each effect to be adjusted by foot. The Kay Fuzz Tone was most likely released in late 1968/early 1969. Initially designed as a low-cost-version of the Shin-ei/Univox Superfuzz, this fuzz is one of the Edge’s go-to pedals. Fifty-four years later, JHS is releasing our spin on the Kay Fuzz Tone: the Mary-K. We’ve even added knobs and an expression pedal output for those who want to use it as it was originally intended.

Rather than using a treadle chassis, we allow Mary-K users the option to control the Frequency knob with an expression pedal. We recommend the Nektar NX-P and Roland EV-5 expression pedals, but many other expression pedals should also work.  Be advised: some expression pedals may introduce a hum/noise into the signal chain in high electromagnetic interference environments. Therefore, we recommend using plastic chassis expression pedals with short cables to avoid unwanted noise in a high EMI environment.

USES 9V DC NEGATIVE CENTER. 4MA CONSUMPTION. DO NOT USE MORE THAN 9V DC, OR YOUR WARRANTY WILL BE VOIDED. 
THE MARY-K DOES ALLOW FOR BATTERY OPERATION VIA A SINGLE 9V BATTERY. JUST LOOSEN THE TWO REAR SCREWS FROM THE ENCLOSURE AND THE BACKPLATE WILL SWING OPEN. ON THE INSIDE YOU WILL SEE A BATTERY CLIP TO INSTALL THE BATTERY INTO.
THE WORDS KAY MUSICAL INSTRUMENTS, MARY KAY, KAY FUZZ TONE, TREMOLO, WAH WAH AND BASS BOOST MAY BE REGISTERED TRADEMARKS. THE JHS PEDALS MARY-K IS IN NO WAY AFFILIATED WITH OR ENDORSED BY KAY MUSICAL INSTRUMENTS OR MARY KAY INC.
