Maple guitars are bright, but even hollowed out, maple will be a heavy guitar body. Also, maple won't give you that classic twang sound as well as swamp ash or alder. You'll be able to get that sting you want from a good pickup and good body.
Thinlines sound different than solid body guitars. If you are really after that classic tele tone, a light swamp ash body and good set of pickups is the way to go.
I invite you to check out posts by Arlo West and his pinecasters. They sound great.
Also, here is a link to my pinecaster. Sound clips are on the second page.
Not all ash or even swamp ash is the same. You can have a 3.5 lbs body or a 7 lbs body. If you order your blank from a reputable supplier like USAG or others, they will be able to select a blank that will suit your weight needs. Pine also provides a great soudning light weight guitar.
