Can't comment on the LaceSensor, as I've never played with one.
But, the Nailbomb will go heavy and clean with style! I find my Nailbomb is really smooth at higher gain settings, compared to my Mule, which is rougher and more growly, with rich and chimy when clean. I've got mine set to coil split in that PRS type way, using a Schaller Megaswitch, and I can get some pretty good Strat middle/bridge/neck sounds.
Nailbombs are the future!
Hope that helps.
Mark.
