What mag size for Prail mag swap?

[Jack_TriPpEr]

I would like to replace the alnico 5 bar magnet under the rail coil of my Prail neck pup with a ceramic bar magnet to help boost the output volume of the rail coil.

I see the Mojotone website carries a 2.35" size and a 2.60" size ceramic 8 bar magnet. Which of these is the size i need? Or do i need a different size?

Also, there is this thread from Yr 2018 where Frank Falbo himself endorsed the idea of swapping in a ceramic mag in the Prail, but unfortunately the thread doesn't get into details that I need about mag size.

I haven't heard of a 2.6" size. The longest I would recommend in the P Rail is a 2.5", but there is nothing wrong at all with using the 2.35" length.

Thanks GuitarDoc!

its a 2.5" magnet, 2.6" might be a typo?

Don't think its a typo, as website hsmagnets.com also lists 2.35" and 2.6" but not 2.5".

Also, thanks for confirming that the Prail uses a 2.5" mag!
