Hey guys, getting around to sorting out my pedals(finally!!!) and pretty much have all my effects sorted except for the overdrive, as it's been to most difficult to choose. I play alot of Megadeth and Metallica etc but do not necessarily want their sounds, just similar(chunky, heavy etc). Has to be true bypass. I use ESPs with standard(for now) pickups through an ENGL E670 SE with EL34 tubes. I want something to tighten up my sound with distortion and have heard overdrives do just that. Also something that will make the notes stand out and scream and make the palm mutes chunkier. I don't want to be too far removed from the original sound though, I think people use the term 'transparency' for that?? Give me some ideas please, no budget really but nothing extreme(ie $900US+ lol). Thanks guys.
