Yamaha 643 bell flare

[JohntheTheologian]

I'm wondering how close the Yamaha 643 bell flare is to an Elkhart 88H.

While the horn looks very much like an 88H, I know some have said it doesn't sound exactly like an 88H.

Is that primarily due to a difference in the bell?

The reason I"m asking is because I might need to replace the bell flare on my Blessing B8 and I was wondering how the Yammie bell flare might work.

I have always found the Yammie 643 (and 643 II) to be very nimble horns. The 643 bells have a quick response and the horns are very efficient. Being that I have found the Blessing B8 and B88 bells (in yellow and red brass) to be heavier and slower to respond, I would think that the Yammie 643 bell would be an upgrade. Then again, the entire 643 horn is built lighter than the Blessing .547 bore horns.
