Dom you sound really confident . Lets have some fun. Your really confidemnt of your position arnt you ? I mean yamaha cant touch you can they ? How about you write to yamaha and tell them what you are doing and post up their response ???? You can then have bragging rights for years to come and Diki nor i can say a word about it becuase you told us so didnt you ? Dont wimp out now ! Whatr have you got to lose ????? I mean you are so confident of your position right? Ok that might be a bit too risky for you i know :-) How about you post up whatever legal advice you have sought to confirm that you are not breaking any copyright laws by using other manufacturers styles and packaging them when you sell your instruments....oh and by the way post up the name of the Law firm that gave you this advice....if they are brave enough to give it. Go on Dom. Either write to Yamaha or chicken out and post up tyhe legal advice you have recieved.
I double dare ya :-)
