Hi, This question goes to all guitarists and music afficionados. i've been thinking of buying an acoustic steel string guitar and recently found a pretty neat piece by yamaha... model - f 210 at a store in my town. when i looked on their website and searched for the serial no- f 210 , it simply wasn't there at all....they do have an f- 310...which appeared as jumbo to me. is that a dubious yamaha that they are selling or yamaha has not listed or updated the model on the website?. what about gba guitars ...i'm getting a black colored gba for about Rs 3500... the body style is Artist or Nex.
