I'm just in receipt of a Markbass 2X10 combo -- I had to give in. It sounds good, but I'm also in the position of maybe sending it back. It's an as new used one. Here's the problems:
The gain knob crackles when you turn it up; only until about 12 o'clock, and only when you're making sound anyway. Turning it up without playing, it's silent.
There looks like there's some sort of silver line, maybe two or three inches long, along the edge of one of the speakers. I can't tell if it's cracked or not. It doesn't sound like it.
Advice?
