Yes. And no. If I play thru an amp/speaker rig that sounds good to my ears, then if I want that sound again from a different rig it helps to know the specs of the earlier rig. But if I enter a stage and play thru an existing rig and it's awesome, or if I walk into a music store and plug into a random amp and it sounds great, then the sound is all that matters! Particularly nowadays, when almost every stage deploys sound reinforcement (which obviates the need for a big guitar rig), all that matters is the sound experience itself. But let's turn your argument around. What if my default guitar 'requirements' were three single-coil pickups, a 25.5" scale, and an alder body? And if a guitar lacked those specs I refuse to try it? Answer is that I would never have even tried a PRS! But I saw that 408 hanging there, and even though I'm a "Strat player" I sidestepped my tech specs and picked it up. That is why specs don't matter. All that matters is the subjective experience of the sound (for amps), and of playing (for guitars). JMO of course.
