What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
Sets sweep rate only. Depth and stages are fixed, so you get one voice, dialed fast.
Detail 02
Notches move through the frequency range, creating a hollow whooshing sweep. Different from chorus, which detunes.
Detail 03
The effect tracks your picking dynamics rather than flattening them, so hard and soft strokes stay distinct.
Detail 04
Tuned toward the fast, shallow setting heard on Van Halen rhythm tracks rather than a slow ambient sweep.
Detail 05
Sits in the range where you're paying for a specific voice, not a do-everything modulation box.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
The EVH version carries Eddie Van Halen's script logo and is voiced toward his settings. The control layout stays a single Speed knob.
MXR pedals in this line typically run on 9V, either battery or adapter. Confirm what's in the box before you order a cable.
Most players put it before distortion for a thicker sweep, or after for a cleaner one. Both work; try both.
For this sound, yes. The fixed depth is the point. If you want to shape the sweep width and stages, look at a larger phaser.
