Interesting, not convinced in what way? I’d been considering grabbing a Boss tuner to use mainly as a y splitter and reamp box more so than just for tuning, there were a bunch of people saying and doing videos on this in the past couple of years so if it doesn’t actually work that would be a bummer.

Were you using it to re-amp, i.e. run a signal from your DAW or synth through pedals and then into an amp? If you want to just run through pedals and back into the DAW it’s probably a different problem and solution that’s needed.
