Hi all, I got a PRS 30 combo from ebay and am wondering if it's broken. Here is why, it's all high end with very little bass. I have to turn all the trebel down and bright switch off to get it to sound reasonably (with a les paul). I don't know if this is how it's supposed to sound, it doesn't seem right. Other than that it sounds great. Has anyone else experienced this? Does anyone know what's going on?

Thanks!
