MOTU at the 2010 NAMM Show announced the ZBox guitar impedance adapter, and a new major upgrade to its Ethno virtual instrument software. ZBox is designed to improve sound quality with software amplifiers by replicating the impedance levels found on classic guitar amps. Features include authentic matching circuits that emulate two-jack switching networks, and a built-in 16-inch cable for connecting to any guitar input. It offers plug-and-play installation and supports either Mac- or PC-powered audio interfaces equipped with preamps.
