Variax bass guitars Line 6 offered the same technology for electric bass guitars with the 4-string Variax 700 bass and the model 705 5-string bass, but discontinued them in 2007. Workbench Software Variax guitars have a Variax Digital Interface (VDI) port that connects them via an Ethernet cable to compatible hardware like the Line 6 POD amp modelers, or through the Workbench interface via USB to a computer. Note that the (300-700) guitar cannot be connected directly to the computer but requires a Line 6 USB interface or POD Live / Vetta. Workbench is also the name of the software that lets users customize the electronic models—change body type, change and move pickups, and adjust volume and tone knobs function. Users can create customized models and tunings and then save them back to the guitar.
