I am the amp tech and the builder of this website, not the owner. It was my first website build and some things need clarification. My amp business is completely separate from “Gerhart Guitars”. I am “dougMMMMusic”, and also build custom amps as “DUNAMIS”, and as “Pi Amplification”. Please check the amp pages for more info. And please continue to enjoy Sherlin Gerhart’s world class guitars and guitar repair work. This is his business, and his website. Thanks.
