There are 3 main ways to make use of the USB3:

1. You can now start recording tracks on any computer: Desktop or Laptop. Mac or PC. It's easy to carry around so all you need is the USB3, a USB cable, headphones and a guitar and your up and running.
2. The custom designed E.F.R.™ Circuitry is specially tailored to give you a unique sound that really warms up your guitar. You can use the E.F.R.™ Guitar input to record to the computer, or you can just monitor directly to headphones or speakers to hear yourself play.
3. As long as the USB3 is connected to the computer so it gets power, you can use it just like a small audio mixer. The USB3 lets you record and play your tracks from the computer, mix with vocals and keyboards and easily lets you monitor everything all at once.
