I've recently been thinking about the idea of putting a Mississippi Queen in the bridge of my Yamaha Pacifica 604W, but I'm wondering if the different spacing would cause a problem; the guitar has a Wilkinson tremolo, and as far as I know the MQ is only available in standard spacing.
Also, what single coils would you recommend for neck + middle that would be balanced with the MQ - I'm assuming something fairly hot like Irish Tours or Slowhands.
