One thing for sure- there wouldn't be as much "buzz" about the push/pull tone if there wasn't something to it. I was very curious, and was luck enough to get a chance to play a bunch of P/P's at once (various Emmons, Fatback, Bolt-on, etc. courtesy of Mr. Tom Cassella), along with my 2001 Carter D-10 (with TrueTone pickups), for an amazing A/B test. No doubt, the p/p tone is not only special, but there are different flavors of it, depending on the horn and how it is set up (naturally!).
I felt the Carter "measured up", tone-wise, about 85%. The best p/p's had a certain extra 'zing', a ringing, sustaining, thick, resonant quality, that was undeniable. That 15% is icing on the cake, but substantial...but there are trade-offs. Many players feel that there is Nothing Else But a P/P, End of The Story.
I like the fact that the Carter D-10 weighs about 1/2 as much as the p/p, and that I could change the copedant around myself (I added a complex p4 change to the C6 neck successfully, and am nowhere near mechanically inclined).I'm happy with my Carter, tone and feel-wise. Out of adjustment P/P's can be stiff and tough to play, but properly adjusted by knowledgeable techs, they can play as smoothly as all-pulls.
It is akin to trying to find the "perfect Tele" (or perfect woman, for that matter!)- you can spend all your time chasing it! Everything in life requires some kind of compromise. I like the tone of my instrument very much, but I reckon most steel players have a "wandering ear" !
Anyway, I'd rather be honest and complain about my tone being my hand's fault rather than my horn's fault- 'cause it's true!
