I need a wiring diagram for a Ibanez Silver Cadet 4 string bass guitar

The guitar was made at the Saein Plant, Korea in February, 2005.

Depending on the exact model number and condition, it would sell for approx US$600-900. They are quite well regarded.

This bass was made by Cort in Korea, in Jan 2004. They sell used for US$150-250 depending on condition.

You can find that here:

This what I found by googling wiring diagram for Peavey Zodiac EX 4 string bass.

Ask for lite gauge steal strings

The internal workings of the guitar - pickups, potentiometers, switches are not grounded.
Very common.

Replace it with the same size as the original and the original type. The 100 sounds right for the E. Make sure it is the SAME type string as there are non magnetic for some guitars and if you have magnetic pickups the bronze types won't work. There are also round wound, flat wound and some are flattened on one side. You need to make sure the replacement is exact type. Take sample of old to show store clerk.
