MXR Dyna Comp
Debut: 1973
Putting the pop in country licks and helping slide parts sound silky smooth has long been a specialty of this king of stompbox compressors. The Dyna Comp was quickly adopted by ace Nashville session players such as Reggie Young and Jerry Reed—who used the script-logo versions on hundreds of hit recordings—and it was also a key tool of slide master Lowell George.
