Issue 336 of Guitarist magazine was a bumper celebration of all things stompbox, with the team compiling a comprehensive list of the 101 best guitar effects pedals ever produced. Whether for innovation, influence, sound, sheer popularity, or all of the above, each and every unit that made the cut is a tone-shaping tool worthy of a place on a pro pedalboard.

You've probably already seen the 42 best overdrive, distortion and fuzz pedals of all time. Now we've gathered all of the 17 delay pedals and echo units together from the list, so whether you want lo-fi tape warbles or crystalline digital repeats, there's all that and more here.First up is a stompbox take on a classic tape echo unit from Boss:

"Roland’s RE-201 Space Echo is now considered an all-time classic. The RE-20 digitally models that superb tape-based machine in a practical package. We like it a lot."

FAMOUS USERS: (Original RE-201 version) Brian Setzer, Brian Eno
