I have confirmed that it works with the GT-1 and Boss Katana as well.

I have also tested with the Boss BR-80 and GT-001 and this still seems to work 
well for me, so no obvious issues have arisen from making this change.

I did also try the Boss JS-8. This works in Ardour, but capture from command 
line using arecord results in a file of silence. I'll do some more digging into 
this one.
