It it available?
The standard size phat cat is smaller than my tune-o-matic bridge. Does it matter to have a narrow one?

The Phat Cat is not available in Trembucker spacing.

I wouldn't use one in the bridge position of a Strat but if you have a guitar with a tune o matic bridge you should be fine and it should work perfectly.

All that matters is that the two E strings be over the polepieces.

The Rio Grande Bastard which is the same concept as a Phat Cat uses their spacing which splits the difference between the 2. They work great under either spacing right now I have one in a floyd equipped guitar and it rocks.

The JB in my LP is normal spaced, but the TOM is slightly wider, it doesn't make a difference to my ears though.
