I had a look this morning at my Squier Bronco short scale bass.
I changed the pickguard to an orange one which I think looks very good.
I was going to change the pickup from the Strat single coil to a Vanson hot rail humbucker but changed my mind. I don't like how the blades are arched so the outer strings would be about 2mm further from the blades than the centre two - a 33% difference! But I liked the original pickup anyway despite it being low output so will stick with that for the time being.
I was pleased to see that the pots are decent Korean Alpha pots.
