Hi Mark,
I'm just guessing at a few things, and as Stan noted above, I'm hoping someone else will chime in here.

You might try "unfolding" your song to see if you can spot anything.

It sounds like that last chord is getting stuck some way, what happens if you hit the 'panic' button?

I'm thinking this almost has to be something with BIAB, as the SD2 "just works" as every one that has used it can attest too.

Later,
Jim


I'd be completely happy if I had just one more guitar.
