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 guarantees great vibes at all feel-good events where the unmistakable brass instrument sound is indispensable.
Super Light for Heavy Use...
Kids, music students, and wind heroes, take note! 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 on occasions where the expensive brass model would rather stay in its case. Above all, the 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 especially 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 get 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 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 upcoming mountain hikes. Their resilience also makes them the ideal 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, 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!
