4 Stars Boom? Why such a lowtarded star score for such a great piece of gear? I'll tell you. I'll tell you hard.
The EMG plastic knobs SUCK. They are so low quality, on par with the little "Homies" and "Mijos" toys you buy out front of a Wal-Mart vending machine for 25 cents. They have plastic molding, sharp as hell, hanging off of the sides. The knobs are light weight and feel horrible.
The actual chips and arrangement of the system are REALLY awkward and long. One of the circuit boards is 3 inches long. You won't be able to fit that in a lot of control panels I promise you. Super hard to get it in there and even then, you risk bending the wires.
It sounds awesome. It cuts and boosts HARD. The range you can tweek out is amazing, it's just a shame it comes at the price of poor knobs and huge circuit boards.
