Hi, just today I started getting a problem with unwanted distortion. I haven't changed anything recently, so that's not the problem, it's worked perfect till now. I'm playing through a GK Backline 115, so not the most quality combo amp in the world but decent enough. What is happening is that when I hit the strings hard, it seems to distort heavily. It's NOT to do with the volume of the amp or the bass, it would seem, merely how hard I hit the strings. And it isn't gradual or anything. I play soft and its totally clean. I play hard or slap and it sounds like its going through the distortion channel. So I'm assuming this is a problem with the amp, and if anyone has ideas I'd appreciate it. Is it totally blown or is something else to blame? If so, sorry for being a newb! Thanks!
