Question (Might be Stupid)

I am trying to compare a Bach to my Getzen, and can't figure out the Bach Bore labeling system... I did a quick search here, but can't find the answer... (Sorry if this question has been posted before)

What are the real bores related to

M, ML, L, XL, MLV ???

Same question with a Schilke I'm looking at

What is a ML, L???

Do they all compare directly? or does each mfg. have a different numerical bore for each???

Any ideas?

For most horns, the standard ML bore is .459 and the standard L bore is .462.

I just found this on the web, thanks to Dillon Music...

Does this exist for Schilke?

Schilke doesn't publish the bore size on their horns because they feel it is irrelevant. Read this website if you have time:

Although Schilke doesn't actually publish the bore size on their horns, their large bore is about a .463 and their ML is about a .460 Some of their horns have a "step bore" system.

Schilke tends to change bore sizes and tapers in various parts of the horn - the tuning slide, leadpipe, the pipe going from the tuning slide to the third vavle, the bows within the vavle cluster, the bell taper, radius bends of slides, material used through it etc.. some vavle clusters are even a different size...

The bore is measured at the inside diameter of the second valve slide. This only tells you what the measument is there. It really tells you nothing.

For instance Schilke may have two models where this measurement is the exact same. However the horns play, respond, blow and sound totally different from each other due to the other variences in they way they are built from each other.

I have an old doc getzen model with 2 different tuning slides - on has larger than the other - it makes a hudge difference in blow sound and responce just by changing that one part - so i cannot see how what a bore size is matters...
