I have the head-only version of the pathfinder.
It's 15w, trem, reverb. Reliable so far, and has a line out, headphone jack, and the "Boost" switch makes it sound reasonably good. I'm impressed by the workmanship. It definitely doesn't have that "cheap solid-state amp" look, and there's not many Heads out there to choose from (unless you want a tube amp).
The manual is sort of funny too. It's like they gave it to some disgruntled employee to write; full of sarcasm.
only two gripes:
1. I don't know about the combo pathfinders, but the heads definitely require the footswitch in order to turn the Trem Off/On. Otherwise, you can only turn it down, but you can still detect a faint trem at "0"
2. only has one input jack.
