On its right, there’s an Amp Models knob that enables you to pick one of 11 model amplifiers, the Gain knob that controls the preamp and a three-band Equaliser with Treble, Middle, and Bass knobs.

The Volume manages the volume of preamp and changes the distortion. The Power Level enables you to change the level of output power while keeping the same distortion. The Power button next to it turns on/off the device. Below it, there are an Aux and headphones inputs.

This section controls the tubes (aka valves in British English). There are Bias Shift Button and Class Button

The Bias Button operates in 3 modes: off, green and red. It can change the clarity of a sound from a very clear (green) to standard (off) to overdriven (red).

Ther Class Button has only red or green modes. The latter is standard. The former adds distortion nuances.

Next to the footswitch input, there are 1 Bank Button and 4 buttons each turning the User Programs mode on. Below them, there’s a USB port.

The Tap button can help you set the modulation speed and delay of the effect. Finally, Value 1 and Value 2 knobs change the parameters of the effects.
