The NUX Sculpture Compressor pedal offers a consistent volume output level and sharpens the top and bottom edges of your signal. When you start picking your guitar, it will clean the peak notes and increase the sustain by raising the level of decaying notes. Sculpture also contributes to the signal foundation that's fed into the rest of your effects chain. It has two clip modes, which can be switched between "Clean Mode" and "Clip Mode" by holding the switch for one second. The clean mode has a wide limit range from bottom to top so if your guitar slams the limits too hard (like humbucker pickups) it is very suitable to control the compression. You can also dial up a very soft and clean compressor for single coil system guitars in Clean mode.
