Nice work! There is hardly any direct string noise too (which I always get when recording using the iPhone mic).
Hi SB and thanks for the kind words.
Re string noise, the trick is to set the level with the phone in front of the amp but with the mic pointing away from you.
(And I was also playing veeeeeeery softly thru most of it)!
I've also considered dropping a cloth over the phone as a baffle, but not tried it yet.
