Mike Matthews serves up intense, photocell-driven Uni-Vibe-style modulation at an accessible price.

Electro-Harmonix has built some amazing and affordable phasers, flangers, chorus and vibrato pedals over the years. But the Good Vibes is the company’s first accessibly-priced, photocell-driven Uni-Vibe-style modulation pedal.

Like so many great EHX pedals, Good Vibes is designed for probing the outer reaches of an effect’s potential. There’s an expression-pedal jack (why doesn’t every ’Vibe-inspired pedal have one?), and the switch for assigning it to speed or intensity is right there with the volume, intensity, speed, and chorus/vibrato controls. That simple design gesture significantly enhances the pedal’s real-world utility and expressive potential.

At lower speed and intensity settings, chorus mode deliciously reveals its EHX modulation pedigree. It’s rich, fat, and smooth sounding—perfect for animating chord arpeggios and bend-heavy fuzz leads. At higher intensity levels, though, it sacrifices some of the soft wave contours that can make an optical circuit so appealing. The upside to these harder-edged modulations is that expression-pedal sweeps between high and low intensity become uncommonly dramatic. With a biting fuzz in the mix and an amplifier with a lot of low end, the effect can be uniquely deep and dizzyingly effective.

Test Gear: Fender Jaguar, DeArmond JetStar, silverface Fender Bassman, blackface Fender Tremolo


Control layout invites tweaking. Superb expression-pedal functionality. Reasonably priced. Clean, solid construction.

High intensity settings have a very on/off, pulsating quality. Vibrato can sound thin at lower settings.




Ease of Use:



Diatonic sequences are powerful tools. Here’s how to use them wisely.



• Understand how to map out the neck in seven positions.
• Learn to combine legato and picking to create long phrases.
• Develop a smooth attack—even at high speeds.

Knowing how to function in different keys is crucial to improvising in any context. One path to fretboard mastery is learning how to move through positions across the neck. Even something as simple as a three-note-per-string major scale can offer loads of options when it’s time to step up and rip. I’m going to outline seven technical sequences, each one focusing on a position of a diatonic major scale. This should provide a fun workout for the fingers and hopefully inspire a few licks of your own.
