Purchased in the US and used only a few times. It's in near-new condition. --Product Description-- You can get a pretty good sound setting whether you set Sustain and Attack to 0, 12 o'clock, or full. The knob positions are very delicate, so the controls might be a bit difficult to use for those who can't imagine the sound of a compressor, but once you get used to it, you can have a lot of fun creating sounds. Also, the mechanical noise countermeasures for the switches and pots are well implemented. - Model: EGO compressor - Brand: WAMPLER - Controls: SUSTAIN, TONE, ATTACK, VOLUME, BLEND - Color: Blue - Connections: Input, Output, DC Power Thank you for viewing.
