i've got the Phil Hilborne Fat TB as well, and it really does sound fabulous! i can't comment on how it compares to the other boosters mentioned, as i've never tried any of those, but i'd be amazed if they sound any better. and the row of dip switches inside is great for tuning the pedal to suit your rig. but it sounds great even before you touch them, and is more versatile than most already with it's "cut" control. before i bought it, it did seem expensive compared to various overdrives and distortions, which seemed to do more, but since i've got it i haven't felt the need to use an overdrive!
