I have been using search a lot, there are plenty of valuable info. But, there is always one specifics answer that is not always easy to found. I thank everyone who participated in answering my various questions.
--T, that is very interesting. I love Aria SBs a lot you know (second best after Alembics), to me they are like the poor man's Alembic. I have a 600 bolt neck and a 700 thru neck which I am fixing (Plus the beautiful red one I posted the picture), one with steel bridge and the other with brass bridge, both with brass nut and nice lockable machine heads. But one has had a replacement pickup which doesn't sound as good as the original and doesn't have provision for the tap coil switch...
Both are single pickup version, so I though I may as well look for something a bit more exotic than a copy/replacement and came up with this idea of considering fitting a Bad boy pickup...
Now that you are saying that the new replacement is bigger and needs more space, it kind of gives me even more excuses to fit a bad boy in there, if I have to do some routing, I may as well do it for a bad boy.
Saying that, I am open minded, and anything, if the other original SB pickup were to pass away, I would consider the option. So, how did this pick up cost then, and how do you get in touch with the relevant people? Thanks, LG
