Features Blend Like all of our pedals, allows for mixing the compressed and clean signals, ideal for fast compression adjustment (to reduce it you can dial back the blend and avoid having to readjust your Input and Output levels for unity gain). Input Adjusts the gain on the compressor. Besides working great for ensuring clean operation, it also allows for adjusting the threshold over which the compressor starts reducing gain. Higher input settings will result in higher levels of compression. Attack Sets the time until gain reduction begins (higher settings will translate into faster Attack times). Release Sets the time after which the signal goes back to pre gain-reduction levels. Higher release settings will hold the compressed signal for shorter time. Compression Sets the amount of compression (Peak Reduction). Output Sets the output volume of the compressed signal. Dimensions 12×9.4cm (4.72×3.7 in).
