Re: which humbucker do i need for my squier stracoaster
Welcome to the forum.
The TB-4 has two advantages. Firstly, the polepieces will line up better with the strings than an SH-4. Secondly, its baseplate has short elevator "legs" that will not foul the bottom of the pickup cavity.
The disadvantage of the TB-4 is that any colour other than black will be a special order.
