Loop-Master Pedals Loop-Master ABC Loop Switcher w/Tuner Out

The Loop-Master ABC Loop Switcher w/Tuner Out is a guitar pedal switcher for effects control and signal routing, made by Loop-Master Pedals. As its name describes, it provides ABC routing, meaning it switches a signal between three paths, and it includes a tuner out so a tuner can be fed from the switcher rather than taking its own spot in the signal chain¹. For a player, that kind of box sits at the front or middle of a board and handles routing decisions with a footswitch, instead of repatching cables between songs. It belongs to the broader family of switching pedals, and the tuner out pairs naturally with a dedicated tuner pedal.

What it does

The switcher's job is routing: it selects between three paths (A, B and C) and carries a separate tuner out. Loop-Master describes it as part of its "Guitar Pedal Switchers for Effects Control & Signal Routing" range, under the name "ABC Loop Switcher™ w/Tuner Out"¹. A tuner out means the signal sent to the tuner can be kept out of the main path, so tuning happens silently while the routed signal carries on to the amp.

Related Loop-Master switchers

Loop-Master builds several switchers around the same idea, differing in how many paths they route and what extra outputs they carry:

The ABCD models add a fourth path, and the versions with a master out or master bypass give a way to kill or redirect the whole signal from the same box. Loop-Master lists these alongside the ABC version in its line of guitar pedal switchers for effects control and signal routing¹.
