Have you ever experienced some of your equipment getting better sounding over time? I have a GK MB112 that sounded good when I bought it - but great today. I play lots of my MP3 music through it all the time, and I honestly think it has broken it in and opened it up. It's definitely louder, with better, awesome bass response today than it had when I first bought it. My only bass this days, a steel 4 string Ibanez, is sounding tighter and fatter than ever. I honestly think it has improved over time. I can't imagine better tone from a steel 4 string. Experienced anything like this? Think I'm crazy?
