I've run into a slight problem. I've been practicing a year with no amp, (I had been using a friend's, but he had to sell it for financial reasons) but now that I have a new one my bass wont work in it. I know the amp isn't the problem, because I tried my old Squire in it and it plays like a dream. The Squire is passive, so I figured the battery was probably dead in my LTD, but I changed it and it's still not working. Then I opened up the back to check all the soldering, and it all looks fine, as does the jack. I haven't had any power running through the bass for about a year, so I don't see how the electronics could be fried. My only two guesses are that the amp won't accept input from an active bass, or the battery just isn't good. (The new battery was a cheap dollar store one.) The amp is a Roland Cube 30 Bass. Does anyone know what the problem might be?
