Ninja by Gurus is the father of all distortion pedals. There are no integrated circuits and clipping diodes inside the Ninja.
The Ninja uses one of the Gurus patented HyperFET circuits, Class A FETs and real preamp tubes that operate at high voltages. Thanks to this, the Ninja can perfectly reproduce up to six fresh gain stages.

However, the Ninja is quiet where it needs to be. Engineers at Guru have put a lot of effort into giving the Ninja a superlative tone and at the same time ultra-low noise. This is achieved with true bypass switching circuits and gold pin relays. The settings allow you to precisely shape the tone to your liking, whether it's a soaring lead tone or a killer rhythm part.

On the outside, the Gurus have also pushed the Ninja's design to the limit. The innovative, bolt-free Aero-Space aluminum housing construction is simply the sleekest, cleanest and most functional pedal ever. The Ninja is the first in a series of tube pedals in such a reasonable, smaller size with a top jack configuration.
