An innovation that once made a splash in the music scene is making a comeback. Magnatone guitar amplifiers- featuring the iconic pitch-shifting vibrato effect- are back. More than 40 years after the original company in Los Angeles folded, a St. Louis startup bought the legendary Magnatone name, releasing a new line of six different Magnatone models. Magnatone engineers are using the patented vibrato circuit from 1958 as their design platform, bringing back the original pitch-shifting vibrato effect and making improvements for modern amp designs. Some musicians are calling it a ‘rockin’ resurrection’.
