All user reviews for the Vertex Effects Systems Ultra-Phonix HRM

It sounds good.
Obviously I didn t compare to a dumble amp (and if so which one, etc....).
But it s a nice and articulate Overdrive.
Going in the Marshall direction to my hears. A Guv'nor-ish tone.
The settings are very precise and can go from very few to a lot.
Small enough to not kill your pedalboard. Heavy and solid metal.

Only minus are the 2 bigger knobs potentiometers are so smooth that everytime you put the pedal somewhere the settings are changing.
