LEGENDS OF FUZZ
MARY-K
Although Kay Musical Instruments was founded by Henry “Kay” Kuhrmeyer
in 1931, they didn’t enter the guitar pedal market until the late 1960s with a
series of knobless, treadle-based plastic pedals: the Fuzz Tone F1, Tremolo
T1, Wah Wah W1 and Bass Boost B1. Fifty-four years later, JHS is releasing
our spin on the Kay Fuzz Tone. We’ve even added knobs and an expression
pedal output for those who want to use it as it was originally intended.
CONTROLS
VOLUME - Controls overall output volume. Left is less, right is more.
FREQUENCY - Controls the frequency response. Left is darker, right is brighter.
JHS MODE - Increases the fuzz level with more pronounced mids.
JACKS
INPUT -1/4” jack on the right side of the pedal.
OUTPUT - 1/4” jack on the left side of the pedal.
EXPRESSION JACK - Plug in an external expression pedal with a TRS cable to control the frequency
response while playing.
POWER - 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. Have fun!
