The CKK Electronic Omni Boost MK2 is an analog boost pedal from CKK Electronic that combines two boost voices with a buffer. RockBoard's PedalPedia describes it as "a diverse guitar pedal for both live and studio applications," aimed at versatile guitarists who play both clean and driven songs1.
Two boost voices and a buffer
The Omni Boost consists of two boost types: fat gain and clean gain1. Each does a different job on a pedalboard:
- Clean gain: The clean signal offers up to 20dB of boost, or can be turned to its minimum and act as buffer signal restoration1. At minimum it stops boosting and simply restores signal strength, the job of a dedicated buffer pedal.
- Fat gain: The fat boost setting increases the mid frequency and is suited to balancing and improving overdrive pedals1. A drive pedal that sits thin in a band mix is the obvious use: the Omni Boost in fat mode pushes the mids underneath it.
Because the two voices cover opposite ends of the job, one pedal can serve as a solo lift on a clean sound and as a mid-focused push into a drive pedal, without changing settings between songs1.
Power and practical details
The pedal runs on 9V DC, center negative, and draws 10mA1. That is a light current draw by pedal standards, so it fits easily on a shared power supply with the rest of a board. There is no battery option or higher voltage requirement given for this pedal.
How it compares
Boost-and-buffer pedals are a small but crowded field. JAM Pedals describes its Boomster mk.2 as "a high-fidelity boost and buffer that adds up to 16 dB of clean level while preserving the natural tone and feel of your instrument"2. The Omni Boost MK2's clean voice offers up to 20dB of boost against the Boomster mk.2's 16 dB, and adds a fat gain voice that raises the mids, which the Boomster mk.2 does not list12.

Questions
What power supply does the CKK Omni Boost MK2 need?
The Omni Boost MK2 runs on a 9V DC supply with a center negative plug, the standard arrangement for most pedalboard power supplies. It draws 10mA, so it sits comfortably alongside other pedals on a shared supply without demanding much current.
How much boost does the Omni Boost MK2 give?
In its clean gain mode the pedal offers up to 20dB of boost. Turned to its minimum, the clean signal instead acts as a buffer for signal restoration, which is useful on long cable runs or large pedalboards.
Is the CKK Omni Boost MK2 analog?
Yes. The circuit type is analog, according to the maker's product page.
What does the fat gain mode do?
The fat boost setting increases the mid frequency. The maker describes it as suited to balancing and improving overdrive pedals, for example adding body to a drive pedal that sounds thin in a mix.
