Okay, I just some simple advice. I am currently looking for a distortion/overdrive pedal that will give me an load of distortion that can stack onto my amp's overdrive without producing the evil screeching noise of death. Price is not a problem and I have a tube Randall tube amp. I haven't tried anything yet but from what I've read I'm thinking about trying an Ibanez Tube screamer. I need it to be true bypass and analog. Thanks for any help.
that maybe a metal zone, not really sure what exact sound you are going for
