I've been mulling over the idea of getting an aftermarket tremolo.
One thing that irritates me about the Fender is the action going up and down as you use it.
Entertaining the idea of a 'Trem-King' as it's a lot cheaper than a Stetsbar.
The disadvantage is in the intrusive fitting it onto your guitar.

Main consideration though is 'am I really gonna be using it enough to offset the cost?'
So the mulling continues

cheers, Mark.
