Surdo 24" x 50 cm - hide heads (goat skin) with aluminium rims

Beautiful Rio style Samba surdo by IVSOM - typical Ivsom design with yellow hardware.
Ivsom´s surdos are very popular in Rio´s and meanwhile also in European Samba schools. They stand out from other brands especially through 3 characters:

  • They are 50 cm high instead of the former 60 cm standard height of the older days. This saves weight, does not really influence the sound and is a lot more comfortable to handle. By now it is quite normal to see 50 cm surdos in Rio´s Samba schools.
  • The rods have threads on both ends, that means that where you are probably used to popping the rod through a bracket with a slit, Ivsom's rods are screwed down flush with the hoop on both ends. No more metal pieces sticking out!
  • To enforce the rim where the heads lies on the shell, the body is flanged around a ring of 10 mm flat metal. Like this the shell is a lot more stable than it would be using just a piece of round wire. But the more important fact is that the rim is now absolutely flat and protects the leather.
  • The main optical feature of this surdo line is definitively the yellow galvanised hardware and exceptionally beautiful and hand-selected goatskin heads.

IVSOM delivers to the Samba school Mocidade Independente de Padre Miguel in Rio de Janeiro, amongst many others. Being a mechanic and caixa player himself, he has the best knowledge and skills to build excellent Samba instruments with outstanding sound qualities.

Important information for mounting goat skin heads:
Hide heads are mounted on wood or aluminium rims after previously being moistened. When dry, the skins tighten up which usually causes the wood rim to twist a bit. So if you put a new hide head on your surdo, it will probably be neccessary to wetten the head with a sponge or a cloth (no need to drown it, just dampen it a little). Then the head will turn soft, be able to stretch and you can easily mount it. Leave the head on your surdo without tension until it's completely dry. Leave it to dry at room temperature overnight, don´t expose it to sun or other things like heating or hairdryers which would make the head brittle. It will fit itself nicely on your surdo and be ready for being tuned and played the next day. Like this you'll enjoy your surdo for a very long time.

Please note: 24'' Surdos can only be sent unmounted due to the DHL girth measurement which may not be exceeded!

IVSOM in Brazil

IVSOM is a small producer of Samba instruments from Rio de Janeiro. The brand is a wordplay: Its owner´s name is Ivson, the Braziliain word for tune is 'som'. Before becoming self-employed, Ivson absolved a profound formation in the metalworking craft sector. Ivson has been an active sambista for many years. He plays caixa for Mocidade, his wife and business partner Luciana plays the chocalho. Therefore he is very close to his clients and knows exactly, what is in demand. Ivson actively participates in the production of his instruments and makes excellent-quality instruments in a very well organized workshop. Some of Rio´s major Samba schools play his instruments. Quite frecuently Ivson surprises us with new features and innovations. Due to his close contact to the Samba scene, he is often the first to convert buzzing ideas and or incitations into useful inspiration for making new instruments. The IVSOM 'vasado' caixas and repiniques created the trend of instruments without bodies.


IVSOM in Europe
IVSOM instruments have gained high recognition amongst Hardcore Rio Sambistas in Europe within the last couple of years. Especially their good workmanship and the excellent sound of the drums have attracted the percussionist´s attenention over here. The number of IVSOM fans is growing larger each year.

Percussion instrumens
IVSOM drums have a couple of untypical characteristics. For example, the tension rods are tightly screwed to the tension hoop. This link is very stable and absolutely free of rattling noises, but a bit more time-consuming in its montage. The surdos have a neat detail concerning the rims of the body where the head rests. The body´s wall is rimmed around a 10 mm flat bar. With this the corpus is a lot more stable than other bodies where wire is used for reinforcement. Like this the drums obtain a smooth and flat rim for ideal head fitting. IVSOM´s reference product is the rocar with 20 jingles.
