We have had some good threads in the Stomp Box sub-forum here about loopers. These usually start as "which looper is best" or similar and often have some good looping info but then those threads sink into oblivion over time. Let's discuss techniques, ideas, and setups here. Other ideas - what kind of music are you looping? What songs work particularly well with a looper? How are you using multi-loop pedals such as Boomerangs and RC-50s and the more powerful software loopers? How are you adding more instruments and sounds to your loops? What works and what doesn't? Got any recorded looping experiments or performances to share? To get things started, here's my low-budget home looping/recording setup: Electric guitars into Fender G-DEC amp, used as a preamp. The G-DEC has inputs for two guitars, so I can switch from Tele to electric 12-string, for example, "on the fly". I send the headphone output from the G-DEC to a small mixing board. A Line 6 POD or multi-effects floorboard would work just as well to provide different sounds with the touch of a button or press of a foot pedal. Bass guitar into bass preamp into mixer. Keyboard at stand-up height into mixer, so I can play guitar or bass and keyboard at the same time - well, not exactly the same time, but you know what I mean. Sometimes I'll swap leads between guitar and keys and the recordings sound like two players trading off - a mediocre guitarist vs. a really crummy keyboard player. Drum machine into mixer. A Peavey Microbass amp works pretty well as a preamp for my Ovation acoustic/electric. I don't use this often, but it works. The headphone jack from the Microbass goes to the mixer. Microphone into mixer. This is for acoustic guitar, hand-held percussion, and strange vocal noises. I have a Boss RC-2 Loop Station with the optional FS-5U pedal to stop the loop with one click instead of two in the effects loop of the mixing board. The control room output of the mixing board sends the mono signal from the RC-2 to one channel of a Fostex 8-track digital recorder. This way I can record "live looping", which I do less and less of these days. Still, it's fun sometimes. The main output of the mixer goes to the aux input of a Fender 25-watt SS 1x10 bass amp. This is my monitor. Finally, when I want to listen to music through this setup, or occasionally loop something pre-recorded, I plug in my mp3 player or computer into the aux inputs of the looper. All this was heavily influenced by Albert Lee Land on YouTube. Check out his videos for some excellent and amazing multi-instrument live looping.
