[Gotoh Bridge replacement for Inspired By John Lennon Casino made in China]

I own an Epiphone Inspired by John Lennon Casino and would like to upgrade its bridge to a more precise bridge. I found a Gotoh Tune o matic bridge on Amazon and read that it is drop in replacement for this guitar model made in China:

Do you agree? 

 

[good casino upgrades?]

The Kent Armstrong pups distributed by WD Music Products are designed by Mr. Armstrong, but manufactured by Dong Ho Electronics in the Philippines.

 

Bottom line, the only upgrade you will do to a Made in China Casino are the Grover tuners and the nut? or would you mess with the pots and electronics also?
