Im getting a mesa boogie amp for christmas and I was wondering if I also got an overdrive with the mesa boogie would I get a good a7x sound? The overdrive pedals I was looking at were ibanez tube screamer, boss super overdive, or if you have any better ideas let me know. Also should I have an overdrive or dont I even need one to get the sound im looking for? thanks everyone
I say maybe a Tube Screamer, BBE Green Screamer, or a Bad Monkey.

Shouldn't Mesa Boogies have enough onboard distortion for heavy crunch anyways?
