Optimum distance between pickups and strings

Hi,
I own a Givson Blue Diamond and would like to know the proper distance between pickups and strings so as to get the best tone. I heard heard that putting very good pickups on a bad guitar (like mine) damages the pickups. Is this true?

 

depends on the pickups, for example the alnico's or ceramics should be no closer than 1/4" ... otherwise the guitar starts to make funny sounds and pickups lots of unwanted harmonics and feedback ..
just experiment and see what suits your guitar the most

 

My pickups are the default ones that come with the Givsons.

 

tone is a subjective matter..so vary tge height till u
get the tone u llike most

 

and the feel of thr guitar changes with action too - so make sure that ur comforatble playing and it soudsn good - ther is a trade off between tone and playability -so find the action with which ur most comfortable...
