Spektra Edge X Tattoo Machines - The Spektra Edge X is the first completely versatile rotary tattoo machine that comes complete with all options. These machines feature a new MultiVise design that eliminates the need for adapters to switch from conventional backstem-style cartridges to screw-on-style cartridges. These machines also employ an adjustable stroke wheel that goes from 2.8mm to 4.2mm with variable options in between. The Spektra Edge X has a "Variable On-the-Fly" adjustable give that allows it to go from no give to full give with just one full turn of the micro dial. Other features that set these machines apart from other rotaries on the market are a unique pivoting stainless steel drive-bar and a self-lubricating slider with ball-bearing stabilization. The Spektra Edge X machines also employ the same HexDrive mechanism found with the Spektra Direkt machines.
