Just wondering if it is better suited with a smaller mouthpiece for the conn 72H.

You use the mouthpiece that works best for you.

The 72H was originally shipped with a "Remington" shank 3B, which would be considered on the small side today. But it was mainstream bass size in its day. Modern Morse taper mouthpieces tend to wobble or not quite fit correctly in the Conn B&S receiver.

I'm using a Bach 1 1/2G in my 72H. I sent it to Bob Reeves and had it converted to Remington shank.

I was using a Kanstul George Roberts (1 1/4ish) mpc when i had my 72H. I had also changed the leadpipe to a Bach 50 leadpipe which made the horn rocking!

If you stick with the original leadpipe you'll need to get a Remington shank so the mpc will sit flush and not ruin the leadpipe.

A good tech can pull the leadpipe and a stock Bach 50 pipe is in the $50 ball park last i looked. The drawback to pipe pulling on old horns is sometimes the damn things don't want to come out and get mangled.


Good luck.

I was on a Laskey 85MD at the time I was borrowing one from a school.
The previous owner had already had the leadpipe changed so the piece fit fine.
FWIW, my Laskey worked just as fine on that horn as it did on everything else. I liked the 72H considerably more than the Yamaha I was used to, even without the second valve. Absolutely fantastic instrument.

I used old Bach 1.5G on the 72H I borrowed. It was a good match for the horn but if I was playing it on a regular basis I'd look at 2G or 3G or even better a Doug Elliott combo.

So what happens to the sound on an unmodified 72H if you go to a bigger mouthpiece? I'm on a 1 1/2G now and considering going to a 1G or Shilke 60 to get easier pedals down to pedal F.

I would think a different 1-1/2G or some woodshedding to be a better fix than a bigger mouthpiece. A large rim and a more balanced ( for the horn ) cup/throat/backbore might help you as well. I like rims in the 1.14” - 1.15” range, but I have a Bach 1-1/2G from the late 60’s that’s absolutely rocking in a smaller bass trombone.

Had one borrowed for a bit and used it with a Wick 2NAL. Wick says it compares it to a Bach 1.5G Really liked the narrow rim. Use it on tenor for lower parts also.
