I hadn't owned an active pickup bass until I bought a Spector Rebop 5 in december. Don't leave it plugged in when you've stopped practicing. I didn't realize it run down the battery. Took it out for a gig a couple of weeks ago, during the first song of a 3 song medley, the sound started to cut out. I panicked. Connection? My wireless? No the battery was dead. And I really needed a 5 string that set. Took the sound guy 3 songs to get the battery changed. Not good. valuable lesson learned. What a dufus!
