Dual-loop AB footswitch pedal that lets you switch instantly between two effect loops or two amplifiers, with a dedicated tuner output that mutes the signal while you tune. Key benefits - Fast, reliable switching: Two-loop channel switching lets you engage Loop A or Loop B with a single tap, so you can change entire effect chains or amp paths without re-patching or adjusting individual pedals. - Hands-free control: AB foot switch design gives you seamless switching between effects and bypass modes from the stage or rehearsal without reaching down. - Simplifies complex rigs: Use the unit as an effect-switcher or an amplifier selector to route a single signal to multiple amps or combine different effect chains into one setup. - Silent tuning: Dedicated tuner output mutes the main signal when active, so you can tune silently while keeping your performance signal intact. Function and compatibility - Functions: two loop channels, AB footswitch control, amplifier select capability, and a dedicated tuner output that mutes the signal when used. - Compatible with standard pedal and amplifier setups: integrates with existing effects, amp inputs, and tuner pedals without changing how your pedals are wired or how your amps are configured. - Foot-operated design keeps your hands free for playing. Performance and usability - Instant switching between loops and amps reduces stage tap‑dancing and keeps song changes clean and predictable. - Preserves your signal routing by switching whole loops rather than individual pedals, making it easier to replicate tones and setups. - Simple, clear operation designed for live and studio use. Practical use scenarios - Live performance: Switch from your clean chain (Loop A) to your lead/overdrive chain (Loop B) between song sections without changing pedal settings. - Amp switching: Route your guitar to Amp 1 for rhythm parts and Amp 2 for solos, using the AB function to select the active amplifier instantly. - Silent stage tuning: Send your signal to the tuner output to mute the PA/amp feed while you tune, then return to the main signal without retuning settings. What this product solves - Eliminates the need to rewire or manually bypass multiple pedals during a set. - Reduces setup complexity by consolidating loop and amp selection into one foot-operated device. - Keeps tuning quiet and unobtrusive, preventing unwanted noise during performances. Compact, pedalboard-friendly approach with straightforward wiring and footswitch control makes it practical for gigging musicians and home/studio setups alike.
