I've been steadily learning more and more about guitars and amps for the past 7-8 years. I take great pride in what I've learned. One thing I know for sure, the more I learn, the less I realize I know. Furthermore, the more I learn, the more skeptical I become of what I read or hear (books, internet, forums, dialogue). I've come to this conclusion - I don't know squat... maybe <10% in general knowledge... maybe 20% of specialty knowledge (Fender Strat/Tele & Gibson legacy products). If I don't know an answer, especially regarding historic significance/accuracy, I never ever seek general population advice on a guitar forum. Opinions do matter, and for less significant things have some value. There is a MASSIVE amount of product knowledge available. There are some trusted purveyors of fact. There are FAR TOO MANY 'subject matter experts' who openly discuss seemingly accurate topics of value... whether broad-brush comments regarding a specific manufacturer's production processes during a distinct period, or the minutiae of metallurgy in the 1956 Gibson ABR-1 and its affect on the sonic signature combined with other materials & electronics that make the Les Paul of the day. Admittedly, I'm one who used to place value on unqualified opinions. No longer. Not since about two years ago when I began to see discussions regarding guitars/amps/pedals and the incessant bickering between two or more SME's, all insistent their opinion is correct WITHOUT QUALIFYING themselves or divulging their references. It was then I realized someone here doesn't know what they're talking about - which one should I believe... there's only one truth here. So, that said, what do you think people should do - those who comment on: other peoples FOR SALE threads; burst the happy bubble on NGD threads; etc.
