Radial BigShot I/O

The Review

Every guitarist has a "what if" scenario. What if I could quickly switch between two guitars with different tunings? What if I could run my acoustic and electric into the same pedalboard without tone-sucking buffers? What if I had a dedicated, always-on tuner output? The Radial BigShot I/O exists to answer these questions - a foundational piece of gear for working musicians who value reliability and pure tone above all else.

First Impressions & Build: Built Like a Tank

Pulling the BigShot I/O out of the box, you immediately know it's a Radial product. The heavy-gauge steel housing and tough textured paint scream roadworthy, the footswitch has that satisfying, solid clunk, and the knobs feel robust.

Features at a Glance

Two high-quality inputs let you connect two different guitars - a standard-tuned electric and a drop-tuned beast, or an electric and an acoustic. A true-bypass SELECT footswitch toggles between them, with a bright LED showing the active input. The BRIGHT switch adds a preset high-frequency boost to compensate for long cable runs or a pedal-heavy board.

The TUNE BONE knob blends your dry signal with a buffered, inductor-driven signal, so silent tuning sounds clear and musical rather than dead. The MUTE switch engages that circuit, and the always-active TUNER OUT means you can leave your tuner on without interrupting your signal chain.

In Practice: Solving Real-World Problems

Switching between a Telecaster and a Les Paul was seamless, with no tone coloration or loading of the pickups. An acoustic-electric with an onboard preamp and an electric guitar ran side by side flawlessly. Into a dark-sounding amp on a long cable, the BRIGHT switch added just the right sparkle and string definition without turning harsh.

Who Is It For?

Gigging musicians who use multiple guitars, session players who need to adapt quickly, and tone purists who want a dedicated tuner output without compromising their core signal. It's a small investment for a significant upgrade in stage reliability and tonal integrity.

The Verdict

Final rating: 5/5. The Radial BigShot I/O is the kind of gear you buy once and never think about again - because it just works, perfectly and forever. It might seem superfluous if you only own one guitar, and the Tune Bone may be niche for some, but Radial has once again delivered a masterclass in practical, pro-grade engineering.
