mrsoul: OK, great:-), i will listen some more to your files and then decide what to buy, its between the juicebox and the boostbox and the later have the "knob adjusting feature" so never need to having the MD up screwing around adjusting levels + i think its more suitable for all kinds of recording sitautions. Using a batterybox my experiance from reading is that it gets very low level, so you have to amplify it a lot, perhaps not get all details of the show. Am i thinking right ?, have you used a batterybox apart from your new boostbox ?
