- Four-knob design provides excellent control and gives the user the ability to precisely shape their instrument’s dynamics. - The Sustain knob controls the amount of compression applied to the guitar signal. - The Attack know adjusts how quickly the compressor recovers. As Attack is turned clockwise the pedal’s response is slower and more initial pick attack comes thru. - The Blend knob adjusts the mix of the dry and compressed signals. - Volume controls the overall output level. - The Pad switch pads down the input signal to prevent undesirable distortion if the Tone Coret is used with high output humbuckers, bass guitar, etc. - True Bypass for maximum signal path integrity. - 9-Volt battery included, also accepts optional EHX 9.6VDC-200mA power supply
