T-Rex Magnus Review - Premier Guitar

premierguitar.com

T-Rex Magnus impresses with its intuitive design and solid sound quality, especially in the analog overdrive and distortion department. It offers a practical solution for those seeking a streamlined multi-effect unit for live performances, with handy preset modes to switch between configurations effortlessly. However, its tuner lacks an alphanumeric display, complicating tuning tasks when strings are significantly out of tune. Additionally, while presets save effect combinations, individual settings aren't stored, which may be limiting for some users. Despite these drawbacks, at $399, Magnus stands as a valuable, gig-friendly multi-effect option.

Review: T-Rex Engineering Magnus Effect Board | Guitar World

guitarworld.com

T-Rex Engineering's Magnus effect board bridges the gap between bulky pedal boards and low-fidelity all-in-one solutions. With four boutique-quality effects—overdrive, distortion, delay, and reverb—in a user-friendly setup, it’s a boon for guitarists. The board's analog circuitry ensures a clean signal path, enhancing performance compared to separate pedals. The overdrive and distortion deliver rich, tube-like tones, while the digital delay and reverb offer smooth, noise-free echoes. Though the Magnus excels in convenience and tonal variety, traditionalists might miss the tactile experience of individual pedals. Overall, it offers world-class tones and portability at an affordable price.
