The first acoustic tune is a ballad and played in 1st flat position in the key of D on an A harp. The other 3 are in cross harp played using an Electro-voice RE10 mic into a Guyatone Tube Echo into a Kinder Anti Feedback+ pedal into a 14 watt boutique ED amp.
I've seen Carlos live a few times, but have not seen him in this drumless trio with stand-up bass configuration before. I enjoyed these videos very much. Thanks for posting, Carlos. ----------
