I use it for a week. The most interesting feature of this pedal is its all-metal casing is very solid and well designed especially for the stage. The LEDs can quickly whether you are on the right note and the brightness of the LED that intensifies as it was the right tone of the note. This is useful in concert.Les leds to see both day and night. The price is not expensive to build reliability and ease of use. I buy it back again if it was a remake.
