Ya know, up until about 3 or so I was having a not-so-good birthday (yeah it is really tomorrow, but my family decided today would be better to celebrate it on) cos I had to see my girlfriend off and she won't be back for a whole month! So that put me in a real downer mood until lo and behold my parents bring in a nice Gallien-Krueger 400rb combo w/ 10s in it! I was a cancer dancin', I tell ya! So yeah, I'm funkin' out on this little monster and all of a sudden it gets real quiet. And now the thing is acting up quite a bit. It goes from the volume it should be at to half the volume and then it'll jump back up to the reg. volume but overdriven. I've scanned the manual so many times that I know it by memory! Now, I know I'm keeping my volume low enough that it shouldn't be clipping or anything, and I've fooled around with everything, including my bass and my patch cords and yet it's still being a pain! Can anyone out there lend me a hand?
