Same as the standard "Clean/Dirty Effects Switcher" (Horizontal Layout) but with an added switch to combine loops in series at anytime.
Some people have problems using multiple effects through one amp because they use certain ones for thier clean tones and certain ones for thier dirty tones. When they switch to dirty, they have to stomp the clean effects "off" and the dirty effects "on". That's a lot of fancy footwork that not necessary.
EXAMPLES: Put a Chorus, and Compressor in one loop then, put an Overdrive, Flanger, and Phaser in the other loop. Turn them ALL on and listen as you switch from a clean, compressed, chorused guitar to an overdriven, phased, flanged guitar signal with the click of one switch into one amp!! And if you want to nuke everyone, just select the "loop 1+2" switch and watch everyone melt as you are now using the effects in both loops! And if you have an effect that you use for both clean and dirty, (like a Delay or Wah) just run it before or after the Clean/Dirty Switcher and it'll be on no matter which loop you have activated.
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.)
