Hi, I'm going to buy my first bass soon, and I may have some dumb question. But then again, I'm a beginner, and am allowed to ask them ^_^ In specific I'm talking about Ibanez's SR series, but I'm really open to hear how basses from other manifacturers respond to these questions: 1- When using active picups, and the battery dies within a concert, can you continue to play?(does it switch over to passive?); and when it does, except for loss of volume, is there any sound quality difference? 2- I've seen bassguitars, with a simple clicking system, to remove the battery, while others you need a screwdriver to remove a plate in the back to remove the battery. Do you think you could switch-off the battery on most bassguitars, when not in use (in specific about the SR505, but also about other basses.) 3- A curved body, interesting for thin, or very slender people? 4- Neckthru; worth the extra 150 ..and so.. dollars?
