MXR Noise Clamp
Eliminates hiss and excess noise from your effects chain. A single Trigger knob sets the volume threshold. Capable of reducing noise up to 26 dB. Maintains riff definition at extreme gain levels. The MXR Noise Clamp can be powered by one 9 volt battery (accessed by removing the bottom plate of the pedal), a Dunlop ECB003 AC adapter (ECB003E in Europe) or a Dunlop DCB10 DC Brick power supply.
