We went out to test our busking equipment outside a small chapel near Alcalali in Spain (Ermita San Juan). Greys filmed it all on my Nokia Lumia. I am using a Korg Wavedrum, a JamMan looper and a dobro, plus two small mixers for a 4 channel recordiusing Mixcraft, straight into my laptop. The whole thing was powered by a 12 Volt leisure battery.
