Channel switcher voor (gitaar)versterker met ingebouwde loop functie. Door mij gebruikt om het kanaal van mijn Marshall te schakelen en bij clean een extra effectsloop/effect te activeren. Zie onderstaande omschrijving van de fabrikant:

Turn on or bypass your favorite tone sucking effect(s) and change the channel on your two channel amp all at the same time.

Say you want an EQ to come on only on the drive channel of your amp and when on the second channel, you want that effect off.
Connect the EQ in the loop.

Connect a cable to your channel switching jack on your amp to "Channel" on the Loop-Master.

If the effect(s) that you want in that loop are on but is on the wrong channel, flip the "Line Polarity" switch once and you're calibrated.

Works with any amp that requires a single 1/4" mono cable for switching channels. If in doubt, see your amp dealer or contact your amp manufacturer. (If you have an amp that uses TRS, you will need a stereo cable and a stereo to dual-mono connector for this to work. Let me know if you need either or both items)

DIMENSIONS: 4.3" X 2.3" X 1.2" (MXR-Sized)

LEDS: For the 9V DC Jack, these units require a 9V AC adapter with a Boss/Ibanez style 2.1mm barrel plug. If you do not have one, we have these in the "Accessories" section. (Unit will work without LED's. The LED circuit in any Loop-Master™ unit does not affect tone.)
