Re: Poplar Or Alder ?
IMO Poplar is not a bad wood (James Burton actually specifically requested it on one of his signature teles) bust just because it's inexpensive doesn't mean its bad. To my ears, poplar has a tighter low end, less mids, and snappier highs than alder does. It's a different flavor. Some people like it, others do not. I have a poplar MIM strat that sounds just fine to my ears.
It's true that it can be very ugly, so it's not for use with graphics. It often has nasty grey/green mineral streaks in it.
