The Tanabe TV Zenkudo is a handcrafted, boutique overdrive/boost pedal designed to replicate the tone of the legendary Zendrive. It’s a clone of the original Zendrive, with a clipping diode switch and using the 4558 opamp instead of the AD712 opamp in the original. This pedal is capable of producing a wide range of tones, including Dumble, Marshall, and original Zendrive-inspired sounds.
