The magical combination of tremolo and reverb is the earliest example of a perfect guitar effects marriage. First pioneered within historic amplifiers of the 1960s, this harmonious coexistence has made its way onto countless records and performances — from early surf, swampy bayou blues, spaghetti westerns and film noir soundtracks, to modern-day indie rock. As music moves forward, guitarists continue rediscovering the inspiration provided by this perfect pair.
