The JangleBox J-Boost is a clean booster that combines both power and refined sound. Designed to be used in conjunction with a compressor, it is an ideal companion to many compressors, including the JangleBox. The J-Boost itself is non-compressive. Equipped with an equalizer, it is a total booster that controls and enhances the overall tone. The J-Boost outputs a clean, distortion-free, pure tone. Most compressors have an interaction between Attack and Gain, making it difficult to boost volume while applying a light amount of compression. The J-Boost can increase volume and create a clear, rich output while applying only a slight amount of compression.
