If you want virtually ANY guitar to sound better & louder, pull the plastic bridge-pins out,and replace with solid brass ones , or you can get spun aluminium ones (Martin use them ). Over the past several years,a number of people who have heard my Martin / Avalon /Guild / and ,yes,Yamaha, guitars have switched to solid metal pins,and been "converted" ! Go on, try it !!
      Getting back to thread title---I recently bought a second-hand Guild GAD 40 , cased,for about £ 375-00 GBP . OK, so made in China, but so what ?? Solid Sitka spruce top? Solid mahogany back AND sides ? Martin-style fretboard inlays ? MOP dot-markers ?? Fishman Matrix pick-up ? Very "easy" action ? Lovely tone ? Simple looks ? Really nice ,well-made case ??      Go, seek one out !!!
