I was wondering why lately people were talking more about the older model of TRB 4. They are probably over 5 years old I think. I resume playing bass again 5 years ago and there was TRB II already so I have never experience any of that. Are they a neck-through body or BO. What was the special about it. I am a Yamaha fan, got few models from them and like all so I was searching for this one but not sucess so far.
