Real great quality compressor here. It is in excellent condition and comes with original box. One of the secrets to the Studio Bass’s power is its 3-position mini-toggle and blend knob, which give you a whole lot of control over your tone by letting you mix uncompressed tones alongside the effected sound. Blend back in lows, full range or punch with mids. Killer feature. A real versatile compressor with a whole lot of options, yet easy to dial in.
