Re: What is the difference between SH-4 and TB-4??
Same pickup but different pole spacings to line up with different types of bridges. Basic Rule of thumb, if it has a trem, go for a TB. If it has any other type of bridge, go for the more narrow SH.
Do the outer pole peices line up with the E strings? If they do, you're fine. If not, the pickup will still work but you may want to switch to the TB version to get the poles lined up.
