The Colour Box V2 has all the same functionality of the V1 with many 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.

Features and Controls
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. Rotating the Step knob from left-to-right will increase the gain by the following: 1st is +18 dB, 2nd is +23 dB, 3rd is +28 dB, 4th is +33 dB, 5th is +39 dB.

The Colour Box V2 has a new Hi / Lo switch to control the amount of clean headroom you have available.  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 -20dB pad switch on the right side of the Colour Box V2. This function only works when in XLR input mode and can help tame the volume for high output microphones.

Most Powerful EQ Yet
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 center frequencies for the Shift knobs are Treble 10kHz, Middle 1kHz, and Bass 120Hz, while the Treble, Middle, and Bass knobs boost or cut with +/- 17dB of control.  If you want to boost high-mid frequencies, turn the Mid Shift knob to 3 o'clock or above and increase the Middle knob above 12 o'clock. If you want to cut upper treble frequencies, turn the Treble Shift knob to 3 o'clock or above and set the Treble knob below 12 o'clock. The Shift knobs give you precision control over the EQ for anything you put through the Colour Box V2.

Frequencies controlled by Shift Knobs:

Treble: 1kHz - 15kHz +/- 15dB

Mid: 160Hz - 2.5kHz +/- 10dB

Bass: 20Hz - 400Hz +/-15dB

HPF 160Hz - 650Hz 3dBper octave filter

The Hi-Pass section is enabled by the toggle switch below the Hi-Pass knob. Just flip it up to engage the Hi-Pass knob, which spans from 60Hz to 800Hz with a 6dB per octave slope.

XLR and Output
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.

Warranty Info:

JHS Pedals carry an unconditional “Two Year” full warranty for ANY problem related to the function or operation of that pedal due to faulty parts and/or other internal problem. Simply show the receipt of purchase and JHS will honor it up to two years. JHS does not cover things such as broken knobs, pots and jacks due to abuse.  JHS build them to last but not to be thrown out of an airplane. However, JHS will repair problems that are out from under our warranty like the above at a very reasonable price.  Several JHS pedals have internal trim pots which are set and sealed very carefully for the function of the circuit and it should be noted that tampering with the trim pots will void the warranty.
