The Joyo Vivo from the BantamP series is a very compact and easy to transport 20W guitar head. Vivo evokes the classic British sound, designed to give the wearer the modern, high-gain sound that so many bands around the world use today. In the past, huge, 100 watt guitar heads were turned up to the max to squeeze everything possible out of the amplifier and thus get the most distorted sound possible. This ushered in the era of amps with cranked up gain, often the sound of these amps was called "The Brown Sound", and this is the direction VIVO is taking. If you want to play rock'n'roll, VIVO will be your best friend!
