Folks, I've been battling with my Ibanez BTB405 for a while to get a nice, powerful signal to the amp. I bought myself an Ampeg BA-120 with 220 watts, enough power to fill any club and be a great monitor on an outdoor live stage. The batteries on my bass just died on me, so I bought some regular Panasonic $1.99 for two 9-volt batteries. I put them in. I had to crank my ampeg all the way to 10 on VOlume AND Level, and put my bass's volume to 10 JUST to have a satisfying volume on an outdoor stage. I'm sure that this is not the best that my Ampeg can do, and I'm guessing the problem is the battery. Does it make a difference in amplified signal to the amp if you have quality batteries? If so, what's the best battery to have in a bass to produce maximum signal sent to the amp?
