Those samples I think are usually pretty loud. And have probably been processed a ton anyway.
Try a different profile. Heck, try MANY different profiles, until you find one that works best for you. And you don't have to single-track, you can record a double if you like (you can do ANYTHING you like, of course).
Keep in mind you don't know WHICH guitar, pickup, amp, cabinet, mic, mic position etc etc the samples in logic have been recorded with. You need to experiment with different profiles, my friend
