The iSP Technologies DECIMATOR II is a renowned noise reduction unit. It's highly effective, with a very natural noise reduction that perfectly cuts unwanted noise with minimal impact on the original sound and playing feel. Operation is incredibly simple with just one knob. You can achieve maximum effect by making minor adjustments to suit your environment, without having to struggle with settings. The bypass sound also doesn't degrade the tone, so it can be used constantly without issue. It's a truly reliable unit for high-gain environments, metal genres, and anywhere noise is a concern, such as studios and home recording setups. It also has minimal impact on sustain and spatial effects, so it won't interfere with your playing. The only downside is that the unit is a bit heavy, but in terms of performance, it's a near-flawless and complete noise gate. [Condition] This is a genuine parallel import product. It's a beautiful item that has been used a few times indoors. Operation has been confirmed. There is some surface dullness due to storage, so please check the photos. The box is damaged. Thank you.
