The kma machines mandrake octo shrieker pedal is an innovative sound modulation accessory that offers an unparalleled blend of flexibility and precision. Built upon an improved version of the shriek circuit from the esteemed moai maea pedal the mandrake provides an enhanced upper octave sound enriching your sonic output. The pedal is a testament to kma machines dedication to crafting the most versatile analog upper octave pedal presenting a plethora of tonal options in a user friendly interface. From subtle tone enhancement to outright dual octave grind this robust pedal ensures ultra fast tracking and a wide array of tonal options courtesy of its variable timbre and filter controls. The mandrake pedal isnt just a mere octave up device. Its prowess lies in its versatile enhancements that include a 2nd order low pass filter timbre and individual mix controls significantly expanding the capabilities of the renowned shriek circuit. The filter control refines your upper harmonics for a varied range of sounds from ear piercing shrieks to a mellower synth like texture. The timbre control on the other hand allows you to manage the amount of fuzzy gain in the upper octave enabling a perfect integration of the pedals tonality with your signal chain. With independent mix controls for both the dry signal and affected upper octave the mandrake pedal gives you complete tonal control whether you aim for a subtle descant or a decimating octaval armageddon. The choice is entirely yours with the mandrake octo shrieker pedal from kma machines.
