This is a rare Sumo Stomp bass compressor. It provides strong compression without being overly squashed by the threshold, and it sounds natural, making it one of the top-class modern compressors among pedal compressors. The response to touch is also quick, and the attack and clarity are outstanding, making slap playing clear. Furthermore, the toggle switch in the center is a switch that can be switched for 5-string and 4-string basses, and it responds well to the deep lows of a 5-string bass. However, please be aware that the current consumption is a bit high. All accessories are included. The condition is beautiful, as shown in the photos. Thank you. - Model Name: SUMO stomp COMP - Color: Red - Features: Compressor effect pedal - Accessories: Box, instruction manual - Control Knobs: 4 knobs (Level, Tone, Compression) Thank you for viewing.
