Who the 3421 Classic 1 Flugelhorn Mouthpiece Is For

The Bach 3421 Classic 1 is a deep-cup flugelhorn mouthpiece designed for players who want a larger, more open feel and a full, clear flugelhorn sound. With its extra-large cup profile and #22 backbore, it is commonly chosen by musicians seeking a rich, broad tone while maintaining stable intonation and dependable response throughout the range.

This model is well-suited to serious students, advancing players, and professionals who prefer a substantial cup volume and a medium-thin rim, including players with a thin, robust embouchure who want added depth and tonal breadth typical of traditional flugelhorn playing.

Common Questions about the Bach 3421

Is the Bach 3421 Classic 1 a good choice for professional flugelhorn use?

Yes. The 3421 Classic 1 is a standard, widely used Vincent Bach flugelhorn mouthpiece design, selected by many professionals for its deep cup feel, consistent response, and full flugelhorn tone.

What does the deep 1 cup and #22 backbore do for sound and feel?

The deep 1 cup increases cup volume, which typically supports a darker, broader flugelhorn sound. The #22 backbore is designed to keep the tone rich and clear while maintaining a stable playing feel.

Who is the typical user of a mouthpiece with a thin rim?

Players who use thin rim flugelhorn mouthpieces include lead trumpet doublers, orchestral musicians who require upper-register agility, and musicians with larger, fleshier lips

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.

Extremely comfortable
Color: 02-multicolour (4-pack), Size: X-Large
These are by far the softest and most comfortable underwear I have ever owned. The leg portion absolutely does roll up as so many others have mentioned, however, I did not find that to be uncomfortable at all just annoying that they don’t stay in place. I bought these specific underwear to see if it would help alleviate HS symptoms at all. They have definitely helped with wicking moisture away from the skin. More time will tell if it’s truly helpful for HS. For now, I will recommend these. They are thin, breathable, butter soft, wick moisture comfortable and I would buy again…maybe in a different style next time. I have washed them several times and they seem to be holding up rather well so that is also of supreme importance given the cost of the item. Again, I would recommend this item and plan on purchasing more in a different style very soon.

Eaten by my Thighs
Color: 04-multicolour (4-pack), Size: X-Large
I wanted to love them. Sadly they have let me down. Pros: natural breathable fabric , super soft and comfortable, cotton panty gussets for feminine health and panty liners will stick!! Yay:). And the colors! They are great! But here’s the Con. And it’s the con of all cons. THEY RIDE UP!! Eaten by my thighs. I’m 5’6” and in the general area of 175. I fluctuate depending on how many times I visit the bakery! :) I don’t have a thigh gap but it is not a super tight thigh squeeze. I seldom have thigh climb but these do. I tried two different sizes to see if that made a difference. Nope. I was miserable at a recent theme park in these. I was wearing long heavy dresses and it was quite awkward to yank these legs down non stop. They feel amazing and they have all the requirements 1. Soft 2. Comfortable and stretches with you 3. Breathable with nice thin fabric. Not bulky 4. Natural fibers 5. Great colors If you are a person that is not blessed with Thunder Thighs, please order these. They are great! I wear them at home and to locations that I will not be doing a lot of walking at. I have washed them so many times and they look like new still.

Best Boxer Briefs for Women!
Color: 09-multicolour (4-pack), Size: Large
I rarely give 5⭐️’s but these deserve it! Hands down, the most comfortable material, stitching, waistband, moisture wicking and overall comfort. They sit right beneath my bellybutton, they wash and dry well and they’re sturdy. I have tried 3 styles and these are the best.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.
