Re: Is Poplar and Alder similar in tone?
All poplar guitar I played so far were MIM Strats. They all had tone that to my ears was pretty dead.
Then again - it could've been the cheaper hardware.
A bit late to this party, but had to chime in:
All this talk about wood species and tone is really a bit "tone deaf" to me. Comparing two completely different make / model guitars, one with a poplar body (as a previous poster did), or saying something like all the poplar bodied MIM strats I've played sounded pretty dead is, I think, a bit short-sighted.
Please don't get me wrong, I am not flaming anyone, but, IMHO the main ingredients in guitar tone are the pickups and electronics, pedals, and amplifier. Not to mention strings (gauge and type); and old dirty worn out strings are going to contribute to a duller sounding instrument.
In my opinion, body wood species maybe counts for 10 to 15% of overall tone. I think the wood species of the fretboard counts for more than that of the body, because the strings come into direct contact with the fretboard when playing. I've heard that maple fretboards are a little snappier / brighter than rosewood. And ebony is maybe as dense as maple. Then we also have to consider the affect of the type and thickness of finish put onto the body itself (poly vs lacquer for example).
I agree that all / most MIM strats sound dull, if they have the stock pickups, regardless of the wood species of the body.
You also have to consider the electronics, namely the tone capacitor type and value and it's +/- tolerance.
So, to sum up, if I am to do a guitar build, say a strat or tele, I typically don't care about the wood species of the body. I prefer nice wood grain, maybe a stain, and a thin clear finish (wipe on tung oil or tru-oil), a decent neck. I will always build the wiring harness using high quality pots, caps, wire, switch. But what I think has the most impact on the final tone is the pickups. I'll do my research and use pro quality pickups (Seymour Duncan, DiMarzio, Fender, Lace, etc, etc). And if I use humbuckers (whether full sized or stacked to fit single coil applications), I'll usually wire the guitar for push / pulls so that I can split coils (humbucker becomes single coil when push / pull is pulled). You can also wire for series / parallel, out of phase, etc.
So, great pickups, versatile wiring, and quality electronics. I also almost always use D'Addario or Ernie Ball 10's.
Then of course, play thru a decent tube amp and a few effects pedals.
Now, that's my recipe for shaping tone...
Thx for enduring my opinion, please feel free to blast me if you think I am way off on some of my points!
