Really amazing sound and versatility. New librarian software is a savior of a product otherwise devoid of proper computer support. The device has amazing enough sound to forgive the otherwise really abysmal (completely non-existent) computer software support for setting up and managing rigs and their components. The product is 5 star in every other way but really needs the kind of software programming capability found in all other modern competing products. Having to do everything with the front knobs and buttons gets old quickly. Hopefully Kemper will hear us all making this point and respond with some software to address this one serious deficiency in an otherwise 5 star product and since I ultimately believe they will eventually address this deficiency I am giving it 5 stars even with this one (significant in my opinion) shortcoming.
