This new travel radio looks like a slightly smaller tweed-covered version of an early sixties Fender Reverb unit. Spring reverbs like the Fender are very popular to achieve the wet, splashy surf sound. They are in fact the only way to create that sound, like on classics Pipeline by The Chantays or Baja by The Astronauts.
