I always liked classic Metallica more than classic Megadeth, but Dave's bass tones were miles and miles ahead of what Metallica was doing, even with Cliff imo. His bass always sounds great in their mix.
Good luck with that tone hunt, like others have said, it's probably more about playing like him than gear most likely.
