If I plug a tuner into one of the send outputs on the BigShot EFX, don plug anything into the corresponding return will the signal go to both the tuner and the BigShot EFX output?
The BigShot EFX is set up to provide two options: On FX Loop #1 if you have the tuner plugged into send #1, the tuner will only be active when the loop is engaged and there will be no signal going to the guitar amp output. On FX loop #2 with the tuner plugged into the send #2, when the mute switch is down, the signal will be split to the main output and the tuner. If the mute switch is up, then it will work just like FX Loop #1.
