Lawrence Arms Tone?

[Milk=BadChoice]

Does anyone know what amp Chris from the Larry Arms uses? I'm really digging his tone, on their official website it looks like he's using a Mesa live, but on the 'Great Lakes/Great Escape' live video on youtube, it looks like he has a Marshall. Thanks in advance

I just confirmed that he uses a Marshall through the "Devil's Taking Names" video, anyone know the model though? I'm thinking maybe buying a JCM 800 2205 from ebay.

BTW, this is the picture he's using a Mesa-Boogie.v
