Hi Bruce

You are 100% correct! the bore has far less importance than most trumpet players think.

As makers we can put a leadpipe on that would make a 470 bore horn feel like the most resistant horn youve ever played. Plus we could place chokes , or gaps a certain points to cause further resistance.

Likewise i could easily make a Medium bore trumpet so open that you would be exhausted after only a few minutes from the amount of air required.

The 470 Bore Horn we have in development right now has had several leadpipes made for it whilst we find out what works best for this particular horn. One of the tighter pipes we fitted caused the horn to be far more resistant than my 460,s that have a more open pipe.

One other thing to mention that is very important is the fact that Eclipse horns are not set up in the same way as other horns!! Due to the fact that we choose to tune at the back of the horn and not the front bend, we have managed to have a continuous uninterupted air column all the way from the mouthpiece reciever all the way into the 3rd valve.
This does make the horn more open as the steps that are normally encountered are not there to cause resistance.

However resistance of some degree is required to give you something to push against, but we prefer to cause ours after the valve section.

The bottom line is! do not be blinded by bore sizes! they do have a role to play, but nowhere near as much as you would be led to believe.

If a good maker can balance off the right leadpipe to the right bore horn, he could really get a M/ML and L bore all blowing very similar (resistance-wise)

If you come to the ITG you will see that our new C trumpet has wonderful presence and great power with a 460 ML valve section.
We of course know what else is out there in the C trumpet market and have made a horn with those in mind that WE believe is truly world class in all aspects.
In fact the feedback is that less energy is required to get the same or more from Our C than other C ,s the testers have played (but everyones different!)
Like i say, its how you build the other parts around that section that makes the biggest difference.

Regards

Leigh
