The ISP DECIMATOR provides excellent noise reduction, keeping your guitar sound clean. The metallic casing inevitably attracts fingerprints, but I clean it as much as possible with a clean wet wipe. The markings also seem prone to damage, but there are only slight chips, and I think it's in good condition. Here's the description from the retailer: The new DECIMATOR II is a noise reduction pedal improved by adding cutting-edge, top-of-the-line technology and two new patents (pending) to the original DECIMATOR. Using a mini-plug cable, you can link two DECIMATOR IIs, providing the same performance as the DECIMATOR ProRack G. This linking function allows you to use one DECIMATOR II between the guitar and the amp, and another in the effects loop. The DECIMATOR II features Linearized Time Vector Processing, developed to improve expander tracking accuracy. This results in a smoother expander release response, achieving the clearest release response unmatched by any other noise reduction system, and smoothly eliminating noise during decay. - Model Name: DECIMATOR II - Brand: ISP Technologies - Function: Noise Reduction - Power: 9V DC - Input/Output Terminals: Link Input, Link Output Thank you for viewing.
