The Big Fella has tone that will fill the room! It's massive smooth overdrive has such a fat yet firm low end, that it needs two seats at the cinema. The Big Fella is all about sustain and power, yet it still retains it's attitude. The very transparent voice of the Big Fella does that it blends smoothly with the sound of the guitar amplifier when crancked up and lets the "personality" of the guitar through adding aggresive and bluesy attitude. The Big Fella achieves its fat responsive tube-like overdrive without the common use of diodes, but purely from cascading gain stages much like in a real tube amp, and therefore it is classified as a True Overdrive.
