Sculpture is a mini compressor pedal with professional performance. Sustain and level controls adjust the compression and output, whilst blend gives the ability to add back in some of the unaffected signal to give a more natural attack. Hold down the on/off pedal to switch between soft clip and clean compression modes. Perfect for long sustain chords and clean lead tones.Power supply: 9Vdc (centre-negative power adaptor required)vbCrLfCurrent consumption: 100mAvbCrLfInput impedance: 1M OhmvbCrLfOutput impedance: 20 OhmvbCrLfControls: Sustain.
