The JHS Colour Box V2 has all the same functionality of the popular V1 version with many new and improved additions like expanded EQ controls, a Hi/Lo switch for massive clean headroom, and the ability to pass phantom power to your condenser mics. The Gain section in red has three controls: Master, Pre-Vol, and Step. The Master volume controls the overall volume of the unit. The Pre-Vol controls the amount of gain between the two internal gain stages. This acts as a "drive" or "gain" control, adding more grit, distortion, and even fuzz as you increase the gain. The Step control increases the gain of each preamp stage in five stages. In the Lo mode, you will easily be able to get ultra clean sounds without breakup. Lo Mode is excellent for tone shaping when distortion is not needed. In the Hi mode, the Colour Box V2 will distort much more readily, giving you a broad spectrum of overdrive, distortion, and fuzz sounds. In addition to the Hi/Lo gain switch, there is a -20 dB pad switch which only works in XLR input mode and can help tame the volume for high output microphones. The EQ section in blue has three new Shift controls correlating to its standard Treble, Middle and Bass controls. The Shift knobs adjust the range of frequencies that the Treble, Middle, and Bass knobs control. The Shift knobs give you precision control over the EQ for anything you put through the Colour Box V2. The Hi-Pass section is enabled by the toggle switch below the Hi-Pass knob. The Colour Box V2 has a combination XLR and 1/4" input jack to use either an instrument or microphone. Select your input with the input selector switch on the right side of the pedal labeled INST/XLR.
