Big Mouth Brass J-865 vs J-845

Post by BassTBone »

Looking to try some used Big Mouth Brass horns available which include the J-865 and J-845 models. They're both CC horns that seem to have the same bore sizes (.750"/.787"/.827"). Does anyone know what the actual difference between the two models is? Maybe the J-865 is just a newer version?

Thanks

Ah I see. Same bore size through the valves I guess but the 865 has a wider bell throat and bigger boughs making it a true 6/4.

Haven't tried the 845 but the 865 is definitely a true 6/4.
