mabuhay ka kulas for starting this - 'thread' ba tawag dito?..
i remember four years ago i was asking more less the same questions and i was really lucky that Arie was kind enough to accomodate all of my questions even when he was so busy with all the guitars in his "always-fully-packed-with-guitars" hospital.
searching the true acoustic tone is i found a 'holy grail', an impossible dream.?.
maybe...
a couple of years after i started my quest, i had to stop and think and accept that good sound for us mere mortals is relative to the amount that we can or are willing to spend.
it's easy when you start with Lumanog's or Don Jon's moving up to 2nd hand Morisses or old Yamaha's and then further on to Ibanez'es or Applause's.
From here it will still be alright to move further on to brand new Yamaha's, Ovation's, Takamine's or Godin acoustic's e.g, Seagull's. ... .and then it hits you smack in the face...how much could you still improve? At this price point, which anywhere from 25T to 50T, you realize that you will need to spend ~100T to hear a significant improvement on the sound of your guitar...
True Acoustic Tone - as you all correctly deciphered is a subjective issue.
one can play a Fernando and be totally immersed in your sweet zone in the same manner as another would play his Ramirez with the technicality of a virtuoso.
in the end, just get the best guitar which you yourself has tried. trust only your guts...if it's an SX, good. If it's an SCGC, good.
