Brass Sound in Vibrant Colors!
Good news for everyone who likes 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 on every fun moment and delivers a radiant sound that guarantees great vibes at all feel-good events where the unmistakable brass sound is essential.
Super Lightweight for Heavy Use...
Kids, music students, and brass heroes, listen up! The tuba from the Classic Cantabile MardiBrass line is an attractive instrument perfect for experimenting, inviting you to try new things, and one you'll confidently pull out at occasions where the expensive brass model would rather stay in its case. 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), at the ski hut in Ischgl, or in the Megapark in Mallorca – party animal and stage pro Micha always has his MardiBrass tuba with him and, above all, 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 truly amazing for the price. I would buy this tuba again anytime!"
Top-Notch Features!
If you think durability and precision are contradictory, think again. The combination of the tough plastic body with corrosion-resistant stainless steel valves and brass leadpipe and valve section 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 upcoming mountain hikes. Plus, their resilience 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 survives long, lively hut parties.

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

All in all, it can be used as a training instrument or as a light alternative for marching music.

The only flaw: the water valves. I had to fix them myself to stop it from leaking. I would advise the manufacturers to maybe add a cork seal, which should solve the problem (I solved it by attaching a chair felt).

Certainly not to be compared with a 3/4 tuba. But convinced by low weight for marching use, and also
the sound is round. In the higher registers it gets tight. But all around a tuba for normal use very suitable.

Questions about product
Question by Emi on 05.11.2025
Can the plastic tuba be played just as well in an orchestra? Is the sound similar to that of the tin tuba? Is it recommended for students who have the tuba as a compulsory instrument? Or should we choose a more serious model for semi-professionals?
Answer by Musikhaus Kirstein:
The KT-30BK is a very light and robust tuba that is particularly suitable for lessons, for students or as a handy instrument for on the go (e.g. when marching or outdoors). The sound is surprisingly full and warm for a plastic instrument.
It is therefore highly recommended for school use or as a second instrument - especially because of its light weight and easy handling.
However, if the instrument is to be used regularly in an orchestra or ensemble at a higher musical level, we recommend a conventional brass model in the long term, as it is superior in terms of sound volume and response.
