Nutube Guitar Amp System

A 60W output guitar-use head amp and cabinet set equipped with a Nutube 6P1 together with pre/power amps. The preamp features both clean and lead channels. In addition to Nutube, the power amp combines a ValveReactor circuit, which reproduces a tube/power amp operating environment, and a digital power amp (ICEpower), allowing users to experience fat sounds and details unique to vacuum tubes. Also, wattages can be changed without losing the tone of the power amp.
This amplifier was part of the Nutube announcement event at the KORG booth at Winter NAMM 2015 and was the first prototype to feature Nutube.
