A staple item for bassists! Authentic imported product for your peace of mind! This unit is a bass preamp/D/I that offers a wide range of sound variations thanks to its independent distortion switch. This unit has two faces: a simple yet clear preamp section with a stable 3-band EQ, and a drive sound that completely changes the sound character.It is a popular classic preamp among professionals and amateurs alike due to its excellent sound and ease of use. In addition, when distortion is on, it is possible to mix the original sound with the original sound, overcoming the weakness of a decrease in sound pressure that occurs when distortion is used! In addition, the Gate switch completely shuts out any noise that occurs when driving, so there's no need to worry when connecting to passive instruments! This is a model that we would like to recommend to anyone who is looking for both a preamp that brings out the tone of their instrument and a distortion sound! control: (CL) is for clean, (DS) is for distortion Bypass, Distortion switch, EQ (CL/DS): Bass/Mid/Treb, Color (Preset EQ), Clean Volume (CL), Gain (DS), Distortion Volume (DS), Blend (DS), Gate Trigger (DS) = Noise floor threshold, Gate switch (DS), Phantom/Ground switch (XLR)
