Kanstul 1 1/2G

[pipperz]

Hi guys!

Ive recently picked up the bass trombone from my college, and it came with a Kanstul 1 1/2G. One of my friends who also plays bass said that the mouthpiece is a little small for bass, which had me curious. I tried out my directors Bach 1 1/2G megatone and Bach 1G and both didnt feel right to me (the 1G feeling almost like a toilet bowl). I tried searching up the specs for the Kanstul mouthpiece to compare but I cant find any information on it whatsoever. Does anyone here happen to know the sizing and how it compares to something like a standard Bach 1 1/2G? I play on a Kanstul 1585 if that helps at all.

On paper, it has the exact same specifications as a Bach 1 1/2G. One problem is that no two Bach mouthpieces of the same numbering are identical.

But on paper, it has a rim diameter of 27.00mm, a throat of .276" and a "deep" cup depth, just as a Bach 1 1/2G.

In addition to the above, my recollection was that it would have been included with the 1585 as standard. (There was also a George Roberts piece that was bigger, but I don't remember how much...)

The 1½G was a standard bass trombone size for many years before the "toilet bowl" phase of the 80's and 90's, fwiw. For me, that size is too small of an inside diameter to be effective in all ranges. But I am me, not you.

How does it feel to you?

My advice is not to worry about the exact spec and just practice on this instrument and mouthpiece for a while.

Mouthpieces labelled 1-1/2G range a bit in size, but they are all big enough to make an excellent bass trombone sound with. Of the three you mention, this is the one I would recommend as a first bass trombone mouthpiece for anyone. It's smaller than what most symphony players are playing the US at this point, but standard or even a little bigger than what is common in the UK.

Agreed. Many times students will get hung up on the specs of a mouthpiece, instead of playing it and seeing how it matches with their horn.

Agree, the specs from Bach or other brands is not to trust. I never read the specs, better try and feel the size. I have this Kanstul 1 1/2g. I really like it. One of the best 1 1/2g size out there in my opinion. I have tried mostly all in that size area, (Expert )and there are many good brands out there now. This Kanstul mouthpiece is one of them.
