From the vendor

Project overview

Inspired by the extremely hard to find and buy Shin’s Music Dumbloid, this pedal is a versatile drive that can go from a clean and transparent boost to a tender, touch-sensitive, Dumble-style overdrive.

Introduction

Some people say that it is easier to have a close alien encounter than to find an original Dumble amplifier. Most of you will never see one of these pedals in person, much less play through one. And if you, a friend, or a friend of a friend by any chance of fate discover one, you will find out that Dumbles are not only scarce but astonishingly expensive.

Produced by Alexander Dumble out of his shop, hardly 300 Dumbles are currently in circulation, with many of them crafted for specific clients.

Because of this, the Shin Suzuki’s Dumbloid was born: a Japanese take on the original circuit that meticulously recreates the Dumble sound. But don’t get too excited yet; let me tell you that this one is also scarce and incredibly expensive, with prices above $600 on the US used market.

Our version, The Humanoid, is easier to find and buy and a friendlier approach for the human race in general. This smooth, clean, sensitive overdrive and transparent boost is something you must try. The controls deliver incredibly responsive and provide a large spectrum of tonal options, all of which are extremely good. Moreover, you can stack them, so the gain structures play off one another when used in conjunction.
