Root Loops
This pedal routes your guitar signal through two possible effects loops in series or parallel.
In parallel mode, you have three channels to mix with their own volume controls (FX Loop A, FX Loop B, and your dry guitar signal). This is a great way to use intense distortion effects while still maintaining the clarity of your notes.
In series mode, you have the ability to switch the order of which FX Loop goes into the other. Fuzz before Wah? Wah before Fuzz? Have your pick!
A Master Volume controls the buffered output that protects your guitar signal and adds a volume boost of up to 10 dB.
Each FX Loop Send has a special switching input jack that connects the signal directly to the FX Loop Return when there is nothing plugged in.
There is a standard true bypass footswitch for each FX Loop.
