Hey all. I got a new Czech Spector a couple weeks ago and noticed something that may be peculiar. This is my first active, so I'm not sure what I'm hearin'. If I push the treble up, I get this hissing sound that gets louder the further I push it. No problems with the bass knob, no problems with the treble in neutral. It's not a hum, just a staticy kind of sound. I replaced the battery with a brand new fresh one, so it's not that. The sounds not really noticable when I play(at least to my humble ears) but when I stop, it's there. Any thoughts? Do I need to get it checked out, return it, or is it normal? Thanks again.
