Hello! So it's taken more than a month, but here it is:
My friend Craig played, and I manned the cell phone. I learnt that Aubade (DAW available for Android phones) will record you a stereo track, but there's a phase issue. Easy Voice Recorder Pro (also available on Play Store) will record in mono, unless you fiddle with the settings. Neither could capture the dynamics of the acoustic guitar effectively. You'll hear compression artefacts, and overall it sounds like a tin can. It was a fun exercise though. Listen to a proper recording of the Taylor GS mini here:
