The Sanctuary Perspective

The Radial Shotgun is a compact, high-performance guitar signal buffer and multi-amp splitter engineered to drive up to four amplifiers simultaneously without noise, tone loss, or phase degradation. Operating in either 1x4 mono mode or 2x2 stereo mode, the Shotgun allows guitarists to build massive multi-amp rigs, wet/dry/wet setups, or dual-stereo pedalboard chains. Built with custom-wound nickel-core transformers on outputs 2, 3, and 4, the Shotgun provides complete galvanic isolation between all connected amplifiers, eliminating the frustrating ground loops and 60-cycle hum that plague complex stage setups.

Product Intelligence & Signal Architecture Profile

• Best For: Multi-Amplifier Rigs (Dual Mono, Quad, or Stereo Wet/Dry/Wet), Studio Amp Shootouts, Dense Pedalboard Systems, and Tour-Grade Signal Splitting.
• Sound Character: 100% transparent and uncolored with full frequency preservation, ultra-low distortion, dynamic headroom, and zero active noise floor.
• Compared To: Unlike standard ABY switchers or active splitters that cause severe ground hum and signal loading when feeding multiple amps, the Shotgun uses passive transformer isolation with individual 180° phase inversion controls across all secondary outputs.
• Sanctuary Expert Note: "Running multiple tube amps simultaneously is the ultimate secret to massive stage tone, but connecting them directly creates immediate phase cancellation and loud ground hum. The Radial Shotgun fixes both instantly—allowing you to blend two, three, or four amps together in perfect alignment and dead silence."

Key Features & Stage Engineering Highlights

• Smart Multi-Mode Architecture: Automatically configures for 1-In / 4-Out mono operation or 2-In / 4-Out stereo operation based on input jack connections.
• Transformer Isolated Outputs: Features custom Radial nickel-core isolation transformers on outputs 2, 3, and 4 to block stray electrical ground currents and eliminate 60-cycle ground buzz.
• Individual Phase Inversion Switches: Dedicated 180° polarity reverse toggles on outputs 2, 3, and 4 ensure all connected amplifiers push air in unison without acoustic phase cancellation.
• Individual Ground Lift Switches: Disconnect signal ground paths independently for each output channel to resolve localized stage noise issues instantly.
• Low-Noise Active Front-End Buffer: Unity-gain input buffer preserves your instrument's natural pick attack and frequency response over long cable runs.
• 14-Gauge Steel Chassis: Built inside Radial’s legendary "book-end" heavy-duty steel enclosure to protect internal electronics from mechanical stress and stage abuse.
