The VIVO from Joyos BantamP series is a very compact and portable 20 Watt head. The VIVO brings the sound of a British classic that has been modded to give modern high gain tones. Back in the day, big 100 watt heads were dimed (all knobs on 10) to push the amplifier really hard and make it distort as much as possible. Out of this came the first amps that were modified to have more gain right from the start. Often, the super saturated high gain sound of those days is referred to as the brown sound. Screaming leads, chunky rhythms with a bit of a hole in the middle. this is where the VIVO excels. If you wanna rocknroll, VIVO is going to be your new best friend! The amp operates with a single 12AX7 tube in the preamp and uses a solid state power amp.
