Last October at Berlin2010, I attended a concert of bassist Andreas Bennetzen from Copenhagen/Danmark. He demonstrated and explained his concept of working with live recorded digital loops and electronical effects. I was really courious about his concept, since I also own a Digitech Jam Man Looper and soon figured out that working with loops on stage is much more demanding than expected …For me, the foremost problem is to isolate a loop recording from the loops you’ve already recorded before. When you use them as a playback, the bass (as the large microphone that it is) captures them again, along with the new loop, resulting in a unwanted multiplication … That’s why Andy uses a rather ugly solidbody electric upright bass that doesn’t capture any feedback. Besides that, Andy doesn’t use anthing special: a e-guitar effects processor (phaser, flanger, echo, reverb etc.) with integrated volume pedal, and a digital looper.Andy has recently put some of his tracks at SoundCloud, where you can hear and download them.
