Loop-Master Pedals Dual A/B Switcher – 2 Input / 2 Output Instrument & Amp Selector

LOOP-MASTER PEDALS DUAL A/B SWITCHER – 2 INPUT / 2 OUTPUT INSTRUMENT & AMP SELECTOR

Two A/B switchers combined into one compact utility box.

The Loop-Master Pedals 2 Input / 2 Output Switcher gives you independent control over BOTH ends of your signal path.

The INPUT switch lets you select between two instruments or other audio sources.

The OUTPUT switch then lets you route the selected input to either of two destinations.

That means you can leave two instruments AND two amps, DIs or other destinations connected and select exactly which combination you want right from the pedal.

Think of it as an A/B input selector and an A/B output selector built into one enclosure.

Simple, passive and extremely useful.

WHAT IT DOES

• Two selectable inputs

• Two selectable outputs

• Independent INPUT A/B selection

• Independent OUTPUT A/B selection

• Select either of two instruments

• Send the selected instrument to either of two destinations

• Four possible input/output combinations

• Completely passive audio switching

• No power required

• Premium jacks

• Handcrafted in the USA by Loop-Master Pedals

HOW IT WORKS

The first footswitch selects your INPUT:

INPUT A

or

INPUT B

The second footswitch selects your OUTPUT:

OUTPUT A

or

OUTPUT B

The selected input is routed to the selected output.

This gives you four possible combinations:

• Input A → Output A

• Input A → Output B

• Input B → Output A

• Input B → Output B

Switch either side independently whenever you need it.

TWO GUITARS → TWO AMPS

Here's a simple example:

INPUT A → Electric Guitar

INPUT B → Acoustic Guitar

OUTPUT A → Electric Guitar Amp

OUTPUT B → Acoustic Amp

Now you can leave everything connected and select the instrument and destination from the switcher.

GUITAR / BASS RIG

Another useful setup:

INPUT A → Guitar

INPUT B → Bass

OUTPUT A → Guitar Amp

OUTPUT B → Bass Amp

Select the instrument you're playing, then select the appropriate amplifier.

AMP + DI

The outputs don't have to be two amplifiers.

For example:

INPUT A → Electric Guitar

INPUT B → Acoustic Guitar

OUTPUT A → Amplifier

OUTPUT B → DI / Recording Interface

The output switch determines where the currently selected instrument is sent.

OTHER POSSIBLE USES

• Two guitars → two amps

• Electric + acoustic → electric amp + acoustic amp

• Guitar + bass → guitar amp + bass amp

• Two instruments → amp + DI

• Two instruments → amp + recording interface

• Two pedalboard signal sources → two destinations

• Two preamps → two downstream signal paths

Anywhere you need to choose one of two sources AND one of two destinations, this box provides a simple solution.

NOT AN ABY

This is important:

This is a SELECTOR, not a splitter.

It selects ONE input at a time and routes that signal to ONE output at a time.

It does not send one instrument to both outputs simultaneously.

If you need to run two outputs at the same time, an ABY-style switcher is the better choice.

PASSIVE SIGNAL PATH

The audio switching is completely passive.

There are no buffers, preamps or active electronics in the audio path.

No power is required for operation.

WHY A DUAL A/B SWITCHER?

A normal A/B box solves one side of the problem.

It can select two instruments going to one destination OR select one instrument going to two destinations.

This switcher handles BOTH jobs in one box.

Choose your source with one footswitch.

Choose its destination with the other.

Two inputs. Two outputs. Four possible routing combinations. One compact switcher.
