Interesting observation. I would have said the same about pickups/electronics. Guess at the end of the day we all believe what our own ears are telling us and really no amount other people's anecdotal experience is going to sway what we hear and feel with our own hands. And that's good, really.
That's the kind of thing I was referring to. I will never accept that the material a baseplate is made of could make a bigger different than the kind of wood a guitar is built out of. What I know is this: a dog is a dog, and no matter how many pickup changes I have made to a dog it remained a dog. On the other hand, when I have had a good piece of wood its virtually impossible to make it sound bad no matter what is in it. Again, my own experience and no one else's.
I used to think the same about baseplates...until I started making pickups here at home from parts. To take that further, I even switched baseplates and did before and after recordings. Here's what I found out.
Brass seems to give a particular pickup a warmer sound and nickel-silver a brighter sound. Admittedly, the difference is pretty small, but on back-to-back recordings, you can hear it. It was enough of a difference that I wanted that added 'sparkle,' so I went nickel-silver on my latest build.
Now, about wood and construction...
I have owned few guitars - to include 5 brand new Gibson's - but I have installed pickups in far more guitars than I have ever owned. My experience is probably average, but I will share what I have learned.
One of the worst sounding guitars I ever experienced was a Wildwood Spec Gibson Les Paul. No matter what pickups we put in it, it never sounded good to me, or the owner. We even put in a cloth Gravitt harness, CTS pots and vintage spec Bumblebee tone caps, Thro-Bak PAF's, Virgil Arlo 1959's and David Allen Tru-59 PAF Replicas. We also changed tailpieces and bridge and never got what anyone who played it would call a "memorable" tone. The owner ended up selling it at a tremendous loss and went with a USA Jackson.
One of the best sounding guitars I ever heard was an Indonesian Squire Strat with a Vinatge 6-Screw Trem and a Duncan JB-SH4 in the bridge with the stock, import harness and pots.
Why??? I have no idea and I cannot even begin to explain why these two guitars behaved so differently, but the Wildwood Spec Les Paul cost $5,000, the Thro-Bak's cost $750.00/set, the Virgil Arlo PAF's were $2,000/pair and the David Allen's were $400.0/set and nothing sounded good. It was just a dark, dull sounding guitar. Even 1Mk pots were tried to no avail.
I feel like this was a very good experiment because we were able to run the full gamut of modifications with no expense spared.
What did this teach me???
Two things actually...
1. Brand Loyalty Means Nothing.
2. If result disagree with theory, believe results.
Now, I am not a rich man, but a brand new Gibson in the $5,000 range is "do-able" for me. My issue is, I have just not seen/heard the benefit from these more expensive guitars. Even my Mom's 1979 Norlin-Era Les Paul is just 'OK' sounding. It is not at all memorable, despite it's 'Holy Grail' status.
I just cannot see spending $5k on a guitar when I have been continuously employed in the music industry full-time since 2015 on a much, much cheaper guitar.
Another thing...
Sitting around listening for subtle nuances at home or in the studio is the WORST possible thing you could ever do to yourself. I have spent so much time listening for subtleties that I have missed out on a lot of playing enjoyment. and delayed the completion of a lot of my musical projects.
Every time I need to evaluate how a guitar sounds, I listen to it in a full band at stage volumes. At the very least, I will rent a rehearsal studio and demo my gear at stage volume levels, then go home that night and listen to the recordings.
Just my 2 cents on the subject....
