What is the guitar thru for on VoiceLive 3? Can I use the guitar thru in addition to the guitar stereo out?
The guitar thru is intended only for use when you want to completely bypass the guitar processing in VoiceLive 3 and run to a separate guitar rig, but still capture chord information for NaturalPlay (Harmony/ HardTune etc.).
It's not possible to run the Thru and the Guitar Out simultaneously.
The intent of VoiceLive 3's processing is either/or for guitar. If you're dead-set on sending processed guitar signals from VL3's Guitar Out and having a dry signal, we suggest simply splitting the guitar signal prior to entering VL3's input.
