I can't tell from your pix as it's not detailed enough - but if you have this design:::
--- you will need to have a custom pickguard made.
The Squier basses don't always comply with normal dimen-
sions for some oddball reason - I dunnow why - but the
trench under the PG can be so large to clear the jack and
the pots that a larger PG is required in this low position near
the jack.
