I have a bass with an EMG BQC system and Seymour Duncan Basslines active soapbars. The whole system works great but I noticed that it eats my batteries within a couple of days. If I install new batteries (Duracell), play the bass for an hour, and then put it away for a week or so, the batteries are completely dead the next time I pick it up. I've had this same pickup and preamp combination before and I have never had this problem. Everything is wired correctly. I have no other issues with the sound or the preamp itself. Just seems weird. Is it possible that cold weather drains batteries? I never leave the input cable plugged in when I'm not playing the bass. Any thoughts?
