Protection and climate
BAM's Hightech shell is built in three layers: ABS on the outside, a foam core of injected polyurethane or, depending on the model, Airex in the middle, and a third layer of PETG or ABS on the inside. BAM thermoforms these shells in France, with part of the production based in Thailand.
The interior is foamed in a single piece and set firmly into the shell; as the instrument is fitted, the padding yields to its shape.
The three-layer shell works as a buffer against swings in temperature and humidity. Open the case after moving into a different climate and the instrument meets the new conditions gradually rather than all at once.
A shady spot suits the shell best: in full sun, for example in a parked car, it can warp or blister.
Dry air makes the maple of the scroll shrink and the pegs give, one to two millimetres of travel being normal; damp air makes them stiff. Below 40 per cent relative humidity, pegs may slip and glue joints may open; below 30 per cent, as dry heated air brings in winter, the instrument is at risk, and in the worst case the top cracks. It is above all sharp changes that do harm, such as constant travel between very different temperatures.
As wood moisture rises, the internal damping (energy lost within the wood) of spruce and maple increases, and an instrument can then sound duller; storage at controlled humidity in the case keeps the damping constant.
The Classic double case 2005S takes two 4/4 violins and, according to its data sheet, comes with four bow holders, a string tube and a large outer music pocket. Inside, the data sheet gives 17 cm at the upper bout, 21 cm at the lower bout, a 39 cm body length and 61 cm overall length with 13 cm height; outside it measures 81 × 33 × 19 cm and weighs around 3.4 kg.
In the Hightech double case 2005XL, the practical limit is a body length of around 36 cm, beyond which it becomes tight. No music pocket is provided for the 2005XL.
Our experience
Our experience from shipping is clear: an instrument travels far more safely in a BAM case than in a cardboard box. Every case we deliver passes through our own quality check first.
We make small scratches on the shell almost invisible with ordinary car polish, and we leave alcohol and white spirit well alone.
In our experience an instrument needs a few weeks to settle after a change of climate, for instance after an overseas journey, and a local luthier then fine-tunes the set-up. For the heating season we recommend a humidifier in the case; in our experience the Stretto lasts around a month and humidifies the case quickly and evenly.
Frequently asked questions
Why does my case weigh a little more than stated?
The stated weight is the net weight without straps. Because the density of the plastic varies slightly, an individual case can weigh around 100 g more.
Can BAM cases be stacked?
No, BAM cases should not be stacked; give each case a place of its own.
Can a cracked shell be repaired?
BAM replaces the complete upper or lower shell in France, as a crack cannot be repaired locally. Smaller damage such as pushed-in feet can be fixed with patches.
Will two large violins fit in the 2005XL?
Up to a body length of around 36 cm; beyond that it becomes tight.
Does the 2005XL have a music pocket?
No, no music pocket is provided for the double case.
