The Roland Aerophone AE-10 is a great addition to any sax player's arsenal. With the AE-10, your experience on the saxophone transfers directly to a wide variety of sounds. The unit is programmable through your cell phone or tablet. Roland has done a great job of posting instructional Youtube videos for advanced users. But it is also immediately useful out of the box with ample factory sound settings. I researched the AE-10 prior to this purchase, then went looking for a vendor. Sam Ash had the best price by far, and with professional service and a reasonable return policy, I knew I could buy with confidence.
