I started with the EWI USB and traded for the 4000s. With the USB you're tied to a computer and with the 4000s you can just plug into an amp or PA. I also have Patchman's sounds loaded in and have no need for any other sounds. So, the 4000s is plug and play, the USB is tied to a computer. Later, Ray
