an Eneloop device to fit the situation. Take the newly announced music booster, for instance, which is designed to sit alongside your Tube Screamer, TU-2 Chromatic Tuner and RV600 Reverb Machine in order to keep the juice flowin' even if a breaker trips mid-solo. Truthfully, the device could be used to energize pretty much anything that taps into a 9V power source, and if you're concerned over noise interference, Sanyo assures us that you shouldn't be. The unit -- which goes on sale in March 2010 -- can be fully regenerated in around 3.5 hours, and depending on the drain of the device(s) it's powering, can keep things going for anywhere between 2 and 50 hours. Rock on, as they say.
