I got a Entwistle AT52 set for my TLA-12 build... VERY impressed !!! ... Nice and clear sounding, and reasonably bright top end, plenty of bottom end that isn't boomy. Still need to put a better set of strings than the supplied ones and spend some more time getting the setup just right but right off the bat on a rough 'make sure it all works' assembly the AT52 set certainly gave me that auditory "Wow" moment.
Not sure how they dirty up as being on a 12 string build one tends not to hit the OD pedal, though I suspect on a standard 6 string build they would crunch up quite nicely.
