Compressor guitar effect pedal offering a consistent output level while rounding off the highest and lowest frequencies of your output. When you strum your guitar the NCP2 will in effect balance the frequencies of the higher notes and increase the overall sustain that can be achieved from your instrument. The pedal functions in two modes: Clean and Clip mode. The Clean mode has a very wide compression range, ideal for limiting humbuckers that strain the signal output. This mode also allows you to dial in a very soft and clean compression for single coil pickups. The Clip mode offers a much more aggressive compression. It is perfect for single coil guitars that would need a boost in output. The Blend circuit allows you to mix the compressed signal with the uncompressed one to better manage your overall output. The effect is True Bypass and is powered by a 9V adapter with center-negative polarity (not included). Connectors: 2x 6. 3 mm MONO jack In / Out, Dimensions: 9. 4 x 5. 1 x 5. 3 cm, Weight: 174 g
