I'm playing my acoustic guitar, a 26-year old yamaha cg-100a, fingering in d at 80bpm and this recording can be looped seamlessly. This was recorded with a samson c01 microphone plugged into a behringer u-phoria um2.
Very short beats which can be played as-is, arranged/timestretched into more conventional beats, or loaded into a sampler, thereby playing a beat made of beats.
