Tested and confirmed working, no box. This is a classic analog compressor pedal beloved by many bassists. It's known not only for evening out sound fluctuations and increasing sound pressure, but also for being a "proactive sound-shaping" compressor that adds thickness and a rich nuance to the sound. 【Main Features and Functions】 The greatest appeal of the EBS MultiComp lies in its simple operation and the versatility of tones offered by its mode selection. *Simple operation: Intuitive sound creation is possible with just two knobs: "COMP/LIMIT" (compression level) and "GAIN" (output level). *3 Types of Modes: You can select from the following 3 compression modes using the internal or side switch. NORMAL: Functions as a standard 1-band compressor, controlling dynamics while minimizing tonal changes. Suitable for instruments with a wide dynamic range, such as 5-string basses. TUBESIM: Adds warmth and thickness like a tube amp, with a forward mid-range impression, making it ideal for old-school sound making, such as with Precision basses. MULTIBAND (MB): A dual-band compressor mode that applies compression independently to the low and high frequencies. It is particularly effective in balancing the volume during slap techniques, suppressing the attack sound of the high frequencies while maintaining the richness of the low frequencies. Tones known as the "magic box": Just by connecting it, the sound becomes thicker, making the bass's presence stand out in a band ensemble. Internal Trimmer: In MULTIBAND mode, the internal trimmer allows you to adjust the balance sensitivity of the low and high frequencies, enabling more detailed settings. #bass #effector #basseffector #equipment #homerecording #EBS #MultiComp #multicomp
