I just recenly bought a new bass, its shinny, sound greats when it plays and all that good stuff. But... the catch is that a few wires were loose that I didnt know about. So I found out what it was and welded it back, then the 9 volt battery died so when I went to play it, it didnt work so I put in a new one, THEN about a week later one of the wires leading to the 9 volt came off so I welded that, so then it work. Again when I came back from vacation it didnt work so I changed the battery and it worked, so now the bass works so Iv just been taking the 9 volt out since. What I want to know is why is the battery dying so quick, this has never happened to me before and also did I screw something up in the wiring that would make it do that?
