Q: What is the Four cable method? (POD X3 Live and Pro Only)
A: The “Four Cable” method (4CM) can be used for any effect unit that has an effects loop when connecting to an amplifier that has an effects loop (i.e.
the POD X3 Live). This cabling method allows the end-user to place filters and overdrive units before the preamp section of the amplifier, and modulation and delay effects after the effect loop in the effect unit. This way the amplifier will provide the tones and the Line 6 device will provide the effects (pre and post). Be sure to enable the effects loop, and experiment with Pre-post effect to decide which method works best for you.
Instrument > X3Live guitar in
X3Live effect loop send > instrument input of amplifier
Amplifier effect loop send > X3Live effect loop return
X3 line output > Amplifier effect loop return.
Q: Can I run the two tones separately, such as one tone for "pre" amp sounds and the other for "post" (i.e. effect loop) sounds?
A: An “alternate” method of the Four Cable method is to completely separate the front of the amp effects (i.e. filters and overdrives) into Tone 1, and the time based effects (chorus, delay, reverb) in Tone 2. The tones will need to be panned hard left (1) and hard right (2) in the outputs section (any blending of the tones may result in feedback). Be aware that you will need to have both tones active to get sound, and you need to set up the inputs as follows: Tone 1: Guitar, Tone 2: Aux. Feel free to experiment with the "amp settings" to determine which setting works best for your setup.The connection wiring is:
Instrument > X3Live guitar in
X3Live Live (left) output > amplifier input
Amplifier FX loop send > X3Live Aux input
X3Live (right) output > Amplifier FX loop return
