Letter to my visitors:

Hello, my name is Alex Knappenberger and you have found Grendel Sound! The products on this website are conceived, designed, and constructed solely by me. The products I create are usually a result of my own needs and through a lot of research and development. I pride myself on providing original high quality products at reasonable price tags.

I want you to know exactly who you are dealing with when you choose to purchase from Grendel Sound. If you have any questions, please call me personally at 330-232-2109 and/or e-mail me at alex@grendelsound.com. Sometimes I'm in the middle of something that I can't stop immediately to answer the phone, or maybe I'm in the can or taking a nap! Leave a voicemail and I'll call back! It's a priority of mine that you are able to communicate with me directly about any questions you may have.

Thank you for visiting!
