I'm a proud owner of a 77 BFP and a 77 fp... But I always try other jem 7 from my friends or from some music shop in London and Paris... For me :
aanj makes a little difference
But one thing you must consider is that the neck has a different feeling also...
- Of course the freatbord could be maple and rosewood on a 77 , but you can have ebony
on a 7...
- But the most important thing is that the 77 has a "special wood finish (clearcoat?!?) so the neck feels so natural
... And I love that
!!!!!!!!!!! :P You've got like a real piece of wood in your hand and i never find anything like that on a 7
... It's great on a 7 but it slide more... Does anyone feels the same???
- last thing : On 77 you have "paf pro" dimarzio : I like them... Evolution are very good but too aggresive for my taste!
That's only my opinion, I don't know if ibanez does it on purpose or not...
So it depends on : what is your "cup of tea!!!"
PS : Sorry if you don't undersatn everything, still improving my english!!!!
