The MXR Phase 90 is one of the most iconic phaser pedals ever made, a single-knob, four-stage analog phaser known for its warm, organic, liquid sweep. With just a Speed control, it is effortless to use, producing everything from a slow, gentle swirl to a fast, watery throb that animates both rhythm and lead playing. Its rich, musical phasing has appeared on countless recordings across classic rock, funk, and beyond, and it is famously associated with Eddie Van Halen's early tone. The compact orange enclosure and simple operation make it a pedalboard staple. It sits early in the chain into clean or driven amps, adding three-dimensional movement without thinning the core guitar tone.
The Walrus Audio Fundamental Chorus is part of the brand's affordable, streamlined Fundamental series, delivering quality analog-style chorus with an intuitive, slider-based interface. A dry/wet Mix slider blends the effect while mode switches select different intensities of chorusing from Light to Heavy, making it easy to dial subtle shimmer or lush, deep modulation. Designed as an accessible entry-level pedal without sacrificing tone, it offers warm, watery chorus textures suitable for clean rhythm, ambient layers, and vintage-style modulation. The simple layout makes it beginner-friendly and quick to use, while still sounding musical and usable on a serious board. It suits players wanting straightforward, good-sounding chorus at a budget price, covering everything from gentle thickening to pronounced swirl in a compact, well-built enclosure.
