Powered by Nutube, the MV50 series achieved shockingly light-weight design, and is currently available in three models with differing sonic characters: AC, Clean, and Rock. Each model is capable of amazingly powerful sound that you would not expect from its looks or size, and these units have stunned guitarists around the world. Now, two new types have been added to the lineup: High Gain and Boutique. The fat sense of drive that's distinctive of vacuum tubes — and is characteristic of the Nutube — is alive and well. Painstaking attention has also been paid to the analog circuitry, perfectly replicating even the complex interaction between the components of a vacuum tube amp. Fast response and overpowering dynamics are also major features of the MV50 series.
