OK, so I recently bought a Conn 3 mouthpiece from the 70's in the weird V-shape. I have a Conn 2 of the same series, and I'm kind of a fan of the Conn 2 because it sounds nice and has a decent high range. I figure it wouldn't be a bad idea to experiment with its bigger brother.

Does anybody know how well the Conn 3 plays? Would it be considered too small for Baritone? What's its tone like? I'm tempted to substitute it for my 6 1/2 AL on my smaller trombones but I'm not sure if this is too good of an idea. What bores would be good to use it with?

Sorry for the flurry of questions, I'm just rather enthusiastic because I can start using different Conn mouthpieces with Conn equipment I have.

Actually, I think the Conn 3 is smaller than the Conn 2.

The Conn 3 was used with American Baritone horns (the type that was popular 70-100 years ago).

If you want something a little bigger than the Conn 2, try to find a Conn Remington small shank. They were standard with the Connstellation horns.

The Conn 3 is and has been my choice for trombone mouthpiece. It's responsive and flexible; I am able to articulate, slur, and play any octave and timbre I choose with it. It works great for me, and I love using it. YMMV. Compare your Conn 2 and 3 yourself. Hear for yourself how each works connecting you to your instruments. Hint: Record yourself from a distance in front of the bell to get an accurate idea of how you sound to your audience. Also compare what you hear from behind the bell to what is heard in front of it. Ideally, the timbre should be the same. In reality this does not happen as often as we would like.

I have all 3 of these Conn small-shank mouthpieces – all newer than 70 years old and in excellent condition.

Bruce's recollection is incorrect. Here's what I measure and observe from the mouthpieces in my hand:

• Conn 2: Cup I.D. ~25.10mm; Throat 6.63mm

... Smaller than Conn 3, more bowl-shaped cup; larger & deeper cup & throat vs Bach 6¾C.

• Conn 3: Cup I.D. ~25.35mm; Throat 6.35mm

... Larger, more V-shaped cup than Conn 2. cf. Bach 6½AM. Sharper rim than Bach makes articulations pop.

• Conn <I>Connstellation</I> (Remington): Cup I.D. ~25.55mm, Throat 6.15mm

... V-shaped cup. Small-shank version of large-shank Remington 5CL.

• I find the Conn 3 a nice, flexible, easy-to-play mouthpiece, as Doubler has already noted. It would indeed be a good alternative to a Bach 6½AL for a small-bore tenor.

• I'm still familiarizing myself with the (new-to-me) slightly smaller but slightly more bowl-shaped Conn 2, which might work well on a 0.500" bore tenor trombone.

• The unrelated Connstellation is a nice companion to my Conn 79H (0.522" bore).

I was always under the impression a Conn 3 was on the bigger side of mpcs (close to Bach 6.5). But thinking about how Conn 3s came with 6Hs and some othe small bore horns has me rethinking thar.

The Conn 3 was Rob McConnell`s mouthpiece of choice for just about his entire career . Worked for him.

As I previously posted, the Conn 3 dimensions are not to far from a Bach 6½AM or 6½AL:

• Conn 3: Cup I.D. ~25.35mm; Throat 6.63mm (I just remeasured mine! Throat larger than spec.)

• Bach 6½AM: Cup I.D. ~25.40mm; Throat 6.53mm

• Bach 6½AM: Cup I.D. ~25.40mm; Throat 6.63mm

For some reason, to me the Conn 3 is more comfortable on a 0.500" bore tenor than the Bach 6½AL (which always seems too large). :idk:

Sorry. I must've gleamed over that while i was formulating my thoughts.

I used a Bach 6.5 for the longesr time on my 6H and thought it sounded fine. I only switched because i was having endurance issues playing lead at the end of a long day of blowing. I use a Bach 7 now.

Oops - typo:
