You could try the Black Dog which is, supposedly, like a beefed up Mule. I have one in a LP-type guitar and it is surprisingly punchy, but still has nice cleans. It brings out the somewhat lacking mid-range in my guitar.
If you want hotter, the Rebel Yell excels in Les Pauls & still cleans up well.
I've not played a Crawler in a Les Paul, (only a Strat,) so I'm not entirely sure what that sounds like. But it is certainly very versatile in a Strat, if a little compressed sounding.
