A TS doesn't necessarily muddy up.
I find it actually TIGHTENS the sound up.
The traditional TS has a bass cut and treble cut. The bass cut prevents muddying up and the treble rounds off the sizzle a little. Then there's a good serving of compression. This is why strat (or single coil) players love the TS effect.
Go to TyMusic to try the Liquid Sunshine. Ebenex has the Blackstone and MJM fuzzes.
I don't if you enjoy how a Fuzz Face works with your tone but I really enjoy it and even though does change the character of your sound & feel (but less than a TS) I think its a very natural change.
Note that if you play high gain, the characteristics of the boosting pedal don't effect the original tone so much.
