I've only tried one brand so far thats made me go "WOW!"... It's not a Ovation, Taylor, Martin, Takamine, Godin or any known brand... It's not even a Breedlove nor a Ramirez... It's some really oddball unknown Swiss-Made brand called Schertler. That one acoustic was mind blowing... It's STILL blowing my mind today, and I had only played it ONCE...
Shertler is a reknowned brand of acoustic transducer systems...expensive shit i think....
Didnt know they made guitars though...
I think for everyone... when you play a guitar that makes you go wow... its important to know the specs of the guitar. I strongly believe certain charateristics of the guitar you like are due to type of woods used and can be replicated at lower price points...by diff brands
one of my favourite guitars was an el cheapo takamine ... spruce top with rosewood back and sides... till today im particularly impressed with stika and rosewood combo guitars...
another favourite is Cedar tops!! man those rock...
