Amati Low-C Bass Clarinet

The Amati Bass clarinets (ACL 691 and ACL 692) are available in Prague. Compared with, say, a Buffet bought in the UK, the price difference is (or was) enough to pay for the trip and a few days' holiday for two. In my opinion the instrument compares very well with the Buffet models. It is true that there are fewer adjustment screws, but mine has needed no adjustments in the three or four years I've had it and been playing it (though immediately after purchase it needed some tweaks on the register key and the articulated C#/G# closure lever). The low-C-extension thumb keys may not be to everyone's taste, though I find it satisfactory; it is pictured below.

There are official details of the Amati models on this page of the Amati website..

There are two permanently-connected tone-holes closed by the F/C little-finger keys (or F#/C#): this system gives correct  hole-size and spacing for tonal reasons, and good bass clarinets - but not all - have this feature. On the other hand, there is no open side-hole in the bell, as there is on a Buffet instrument; if this is supposedly deleterious to the tone, it is not noticeable.

The upper register hole, on the neck, applies above right-hand D, with the lower hole taking over for the lower notes D downwards. The lower one doubles as  the throat Bb, for which the usual r.h. side-key Bb is an alternative. The low-Eb extension key + register key gives a rather sharp Bb, and is not usable except in passing or with a lot of lipping-down.)

The right-hand little-finger low Eb key automatically closes the E key, while the thumb equivalent, below, does not. There is no little-finger low D.

Pressing C closes all; pressing C# closes D & Eb; pressing D closes Eb. The thumb Eb key is not particularly useful, compared with right-hand little-finger alternative. It is necessary to hold down the low E, or the little-finger Eb, for D, C# and C to work: this has some disadvantages and some advantages, one of the latter being a quick change from low C to G by lifting the E key.
