Ha... The loop is actually quite simple BUT, I created the upright bass instrument with samples I extracted from Anthony Cox's "This & That" solo double bass album. I put them in Propellerhead Reason's NN19 and just played with my keyboard. I'm actually quite happy with the result and I'm gonna have to get a lot of solo bass albums to create my own library... The guitar samples are from James Carter's " Layin' In The Cut". Get the albums they both are great and you'll realize how far from the originals my loop is ;) Enjoy.
