Personally, I wouldn't use such guitars for metal. Horses for courses. Both of them are very pretty BTW. I'd put PAF style pickups in it like Stormy Mondays, Mules or Riff Raffs.
I have a Gretsch Power Jet wich is s heavily chambered you could call it a hollow body. It has no problems with hard rock ut it does tend to feed back with heavy (metal) distortion at high volume.
Since yours has no maple cap it will be less bright so I think it would be great with Riff Raffs wich will give you a good blues, rock n' roll and hard rock tone and will venture into metal territories.
What sort of metal are we talking about?
Edit: Rebel Yells might work for that guitar too.
