This little pedal can help you get the classic plexi style tone easily. 

The dynamics is like a real tube amplifier.

When you play fast, you can still distinguish the sound of each string with good clean up, 

When it is set at low gain, the sound will not be obscure but still clear. 

That is the big difference from other distortion pedals. 

Built in charge pump device to get a wide head room.

Due to revised circuit design for several times, the noise is controlled at a very very low level.
