Foderas, Ken Smiths, Seis, ACGs...
I would happily have a go on one though if the opportunity arose though. The looks just do nothing for me, and I imagine the sound to be very modern, clinical and sterile - probably totally incorrect an assumption.
Despite this general aversion to this style of modern, silly money boutique instrument, I'm still fairly obsessed with Alembics, partly because they still have that 70s hippy ideal imae, but mainly because I know how awesome they can sound.
