Alder just sounds nice and "balanced" to me. Just a nice smooth sound.
I have Teles made of both, and I'm not embarrassed to say that, unless I stopped to think about it, I probably couldn't tell you which is which.
In all honesty - I couldn't really care less. When I pick up a Tele, the first thing I do - oddly enough - is plug it in, so that I can hear what it sounds like when it is doing what it was made for. I don't go much on the old "I like to listen to a Tele unplugged so that I can hear the tone and resonance" - try standing in front of a crowd of people, strumming unplugged, and saying to THEM "Hey! Can't you hear that superb tone? Can't you detect the resonance and sustain?".
Once the body wood is sprayed a pretty colour than gooped in that thick poly finish, I can't see the type of wood anyway.
I have to ask - has anyone ever picked up a Tele in a store, played it, liked it, then refused to buy it because it turned out that it had an ash body rather than an alder (or vice versa)? Similarly, has anyone ever been approached at a gig, and asked "What type of body wood is that Tele?" - and if you
have, has anyone ever said "ASH??? Jeez - I'm never going to listen to YOU playing ever again - I'm
strictly an Alder man...."
As it happens, my No. 1 is a CIJ 62RI Tele Custom, which, I believe, happens to have an Alder body. It DOES have a nice, "balanced" and smooth sound as the OP says - but only since I took out the dreadful stock Texas Special bridge pickup and put in something which makes it sound way better......
JMHO - YMMV.....
