I came across this very good demo and explanation of the Mojo Hand FX Colossus fuzz by Just Nick. I have to say, that Just Nick is becoming one of my favorite channels on YouTube. I highly recommend subscribing to him. He does a fantastic job explaining what’s going on while playing and demo’ing the pedal. Audio quality is also good and kind on the ears.
The Colossus fuzz is their take on the Russian Big Muff style fuzz (which I personally prefer out of the various Muffs). Controls in clude Tone, Gain, Vol and Mids (Yes.. mids is a great addition). There is also a 3 way toggle switch for different EQ voicings. Pedal is built well, as you would expect from Mojo and looks awesome!
