Don’t think this is possible and prob already covered but can’t find it. Any way to record to tape using master fx as second effect ('ear selected as input), while using the metronome without picking up metronome on tape?
I don’t think so. We all did a metronome battle once where the only sound source was the metronome 
And I think white ear was the only way if recording it.
Thanks for confirming no joy, knew it was a long shot
