Wala sa brand yan sir, and wala din sa price. Sa good brand / higher model, mas marami ka lang "lotto tickets". Pero pwede ka paring manalo sa kahit anong model (given solid body lahat ah). Ibang usapan sa laminates.
Best bet is to have a huge selection available to you, and try as many guitars as you can.
Ikaw lang talaga makakapagsabi kung ano gusto mo. Minsan kasi kahit specified mo na mga kahoy, build, etc. hindi parin ganon yung labas.
Eto personal experience: I got my acoustic after trying out a WHOLE LOT of martins, taylors, etc. Nag-libot talaga ako sa lahat ng shops dulo to dulo and even tried yung mga nakapost sa PM. I did a blind test, even yung mga 200k+ sinubukan ko lahat, pero when I got to try this one mid-level na martin, alam ko na agad na ito na yun. It just blew away the rest of the competition, it wasnt even close.
Sana ma-experience mo rin yon bro. Para sakin: Less reading, more testing!
