Brass Sound in Vibrant Colors!
Good news for everyone who loves to take their wind instrument out on the town: the Classic Cantabile MardiBrass series is here! Fear of nasty tones from temperature changes and worries about dents after lively spontaneous sessions are finally a thing of the past. This indestructible instrument joins in all the fun and delivers its radiant sound to create the perfect mood at every feel-good event where the unmistakable brass instrument’s sound is essential.
Super Light for Heavy Use...
Kids, music students, and brass heroes, listen up! The tuba from the Classic Cantabile MardiBrass line is an attractive instrument that invites experimentation and will confidently be pulled out at occasions where the expensive brass model would rather stay in its case. Above all, its low weight makes the MardiBrass tuba the ideal student instrument!
"The Man with the Blue Tuba" Plays MardiBrass
Micha von der Rampe, aka "The Man with the Blue Tuba," has been performing for some time now on the MardiBrass plastic tuba. Whether at the "Dahoim Feschd" (his open-air event in Brackenheim near Heilbronn), the ski hut in Ischgl, or the Megapark in Mallorca – party animal and stage pro Micha always has his MardiBrass tuba with him and, most importantly, in action.
Micha von der Rampe experiences his "blue miracle" on every stage and is thrilled: "For me, it’s the perfect tuba. It’s light, an eye-catcher, and nearly indestructible – even on the ski slope and in the roller coaster!"
Micha’s conclusion: "Both sonically and technically, it’s absolutely amazing for the price. I would buy this tuba again anytime!"
Top-Notch Features!
So anyone who thinks durability and precision are contradictory qualities is mistaken. The combination of the tough plastic body with corrosion-resistant stainless steel valves plus leadpipe and valve section made of brass makes Classic Cantabile MardiBrass a truly well-rounded package.
Perfect for On the Go
The MardiBrass instruments are so light they won’t weigh you down during moves or mountain hikes. Their resilience also makes them the perfect travel companion.
The ABS plastic tuba won’t mind if you briefly leave it on the beach while the band cools off in the water, and it easily withstands long, merry hut evenings.

Includes Gigbag and Mouthpiece
The lightweight instrument comes with a mouthpiece and, of course, the matching gigbag.
Take it easy, take MardiBrass!

It is 3/4 size Bb tuba and it is smaller that I was expecting. Mechanically it is nicely done and all 4 valves works nicely and they are made like in real tubas.
The bag is very light and nicely done. There is a very long zip to close instrument bag. That might be a problem after a few years use.
The sound is ok, better than I expected, and valves work smoothly.
While playing in a military band you have to play quite loud to to get enough volume. This is compared to my other tuba which is big B&S.
I will use this tuba while practicing and when we have small gigs. This kind of use it is perfect for me. There is a good value for money.
I recommend this tuba also for juniors to be a first instrument.
Thank you
Jukka

I have to say, the paint is great, matte black looks classy, and I don't care if people recognize it as a plastic tuba. The instrument is well made, and after cleaning and oiling, the valves work well. Only the water key on the main tuning slide wouldn't open, and unfortunately I had to force it a little, which caused the sealing plug to break. But it still seals well.
With a normal mouthpiece and a little practice, it produces a good sound and the intonation is surprisingly good.
Unfortunately, the bag that comes with it is not so great. The long zipper makes the packing process a bit tedious. It's better to order the linked gig bag as well. It's much better, offers space for sheet music and a stand, and the instrument is not only better protected but also quicker to pack.

Question by Andreas Rönker on 08.05.2025
What do I need to attach a music holder?
Answer by Musikhaus Kirstein:
A holder for a marching fork is normally already fitted to the tuba. Otherwise, an optional music holder box can be ordered: https://www.kirstein.de/Marschgabeln/Riedl-Notenhalterkaestchen-mit-Scharnierring-16-mm.html
