So about a week ago, my friend gave me his Mark Bass little mark II head and SWR Big Bertha cab. The reason was he simply said didnt have much use for it anymore, as he had switched to playing guitar a few years ago and has grown to prefer it since (heresy!). This is a very good friend of mine and I'm also in his band, so he has no reason to rip me off or anything like that. Anyways, I got the rig about a week ago happy as could be. I've been using a 300 watt solid state for the past 3 years, and never had a head/cab setup. so you can imagine how quickly my excitement dropped to hook it up only to find its not working! Instead I get a loud, distorted bass tone that is terrible. Essentially, imagine something similar Cliff Burton's tone on Anesthesia or an overdriven Chris Wolstenholme's tone in Hysteria.. Not saying those are bad, but its similar to the only sound the head makes. None of the tone knobs made much difference, as it was still a very murky and distorted tone. Tried switching out cables (where in which I confirmed it must be the head and not the cab) and noticed that ANY sound going into the head, even the lightest pluck, the clip light goes on. So is this an input problem? If I open this thing up would I be able to fix it, and if so how? Thank you for any help you can contribute!
