The TC Electronic G-Sharp is a versatile, 19" rack-mount guitar multi-effects processor. Designed for simplicity, it provides premium TC-quality reverb, delay, and modulation effects without forcing the user to navigate through complex, deep software menus.

Key Features

• Dual-Engine Design: Contains two independent effects engines; one strictly for Reverbs, and one for Delays/Modulations (you cannot stack two modulations simultaneously).
• Effects Onboard: 15 studio-grade reverbs (e.g., Hall, Room, Plate) and 15 delays/modulations (Tape delay, Dynamic/Duck delay, Chorus, Flanger, Tremolo).
• True Spillover: Features up to 2.5 seconds of delay with spillover when switching presets.
• Total Presets: 256 effect combinations with 99 user-programmable preset slots.
• I/O & Connectivity: Includes Mono/Stereo inputs, MIDI In/Out for external controller support, and S/PDIF digital output.
• Power: Built-in auto-sensing universal power supply (no bulky wall-wart adapters required).

Interface & Control

Unlike other rack units of its era, the G-Sharp prides itself on a "what you see is what you get" philosophy. Its front panel functions like a traditional pedalboard—you tweak parameters using dedicated physical knobs.

• Tap Tempo: The delay can be synced using either the front panel tap button or an external footswitch.
• Footswitchable: Fully compatible with basic footswitches (like the TC TripTrap) or larger MIDI floorboards for patch changes and true bypass.
