To those considering a purchase, please read this description and the profile as well. I purchased this used 2-3 months ago, but I am selling it to organize my equipment. Original box included. This is a used item, so there are scratches and dirt, but it works fine. The SPARK PIN BOOSTER features a 20dB boost function with adjustable level. - Model Name: SPARK PIN BOOSTER - Brand: tc electronic - Function: True Bypass - Output Level Adjustment: 20dB - Connectors: Input, Output, DC Jack Thank you for viewing.
