Radial BigShot I/O Passive Instrument Selector Switcher

The Radial BigShot I/O is an indestructible, 100% passive instrument selector built for guitarists and bassists who need to toggle between two instruments on stage using a single amplifier or pedalboard chain. Featuring a true-bypass signal path, the BigShot I/O preserves 100% of your instrument's natural tone without active buffer coloration. To eliminate the hassle of readjusting amp volume when switching between passive single-coils and high-output humbuckers or active electronics, Input-B incorporates a variable volume trim control to match levels instantly. Complete with a dedicated mute footswitch and isolated tuner output, the BigShot I/O is a stage essential for smooth, silent instrument changes.

Product Intelligence & Signal Architecture Profile

• Best For: Performing Guitarists & Bassists, Multi-Guitar Stage Rigs, Passive-to-Active Instrument Swaps, and Silent Stage Tuning.
• Sound Character: 100% transparent and uncolored with true mechanical bypass switching, zero signal loading, and zero active noise generation.
• Compared To: Provides a 100% passive, true-bypass alternative to active powered instrument switchers, adding an integrated level-matching trim and mute circuit without requiring external power to function.
• Sanctuary Expert Note: "Swapping guitars mid-set usually means hitting FOH with a massive volume jump or forcing your sound engineer to guess your levels. The BigShot I/O solves this completely—use the passive trim on Input-B to balance your louder humbucker guitar down to match your single-coil Strat, and switch back and forth silently all night."

Key Features & Stage Engineering Highlights

• 100% Passive True-Bypass Switching: Pure mechanical switching ensures your direct instrument signal travels to your pedals and amp completely uncolored.
• Input-B Variable Level Trim: Recessed volume control allows you to attenuate higher-output active or humbucking pickups to match lower-output passive pickups precisely.
• Dedicated Mute Footswitch & Tuner Out: Silence your stage signal for silent instrument changes or route an always-isolated feed directly to your stage tuner.
• Bright LED Status Indicators (Optional 9V Power): While the audio signal path operates 100% passively without power, connecting a standard 9V supply illuminates ultra-bright LEDs for instant visual confirmation on dark stages.
• 14-Gauge Heavy-Duty Steel Construction: Housed inside Radial's signature "book-end" steel chassis to shield internal switches and jacks against stage impacts.
