Located in the Czech Republic, Bach Musik is known the world over for their high-quality guitar and bass parts. They are one of the only makers of a fulcrum-style bass tremolo system that features fine tuners on the bridge (which may account for why they are usually sold out). Their English website is located at: http://www.bachmusik.com/en/

As pointed out earlier by both Hans and Barkless Dog, this trem was once offered as a stock addition to the Washburn Bantam bass.

So many trems - so little time and money... ;-)

Altogether too true, my friend.
