This may be dating myself. Our lead guitar player had a analog tape echo delay in my first band. We played lot of surf music and it came in handy on many songs. When we first heard it we though it was the coolest thing ever.
We started out on surf music too (Surfaris, Chantays, Ventures, etc) Our guitar player had the Fender “echo chamber” as they were called. He also got the very first fuzz, it was the Gibson Maestro fuzztone. (Back to 2019 ... )
