Manufactured in England by Soundtronics, these solid hardwood cases provide for a really professional finish to your MFOS sound generator or single board synth. Available in African Walnut, American White Oak or Maple for a dark, medium or light wood colour respectively. We like the Walnut, it just seems to work so well with the black panels but the other timbers look fab as well.

The case are provided ready assembled, the end cheeks and front / rear rails are 20mm thick. The base is 3mm thick aluminium composite which is located into slots in the rails during assembly. The rails are rebated so as to recess the front panel. The front panel is screwed into place using our Torx head screws (see related products tab above) but we do recommend drilling a 1.5mm pilot hole first.

The case is suitable for our 5U high panels and is available in widths from 3U to 12U. The larger cases can also accept a mix and match of panels, for example: a 12U case could be fitted with a 8U and a 4U panel. Internal height is 51mm so you will need to keep your wiring tidy.

The cases are supplied ready sealed with Teak oil which also provides a degree of UV protection.

As standard, the cases do not have a routed hole in the rear rail to accept our 3-pole power connector but is an option. Some of the MFOS sound generators can be run off batteries, where this is practicable, additional options for integral battery holders in the base are available. As these are universal cases, you should check the module description you intend to house in these cases to see what power options are available and of course the panel width in 'U'.

Choose from African Walnut, American White Oak or Maple hardwood for your case.


Walnut is the darker of the two hardwoods. It is described as golden yellow to reddish brown, sometimes with darker streaks and veins. Color tends to darken upon exposure and with age. Sapwood is a medium yellow to light grey. We further treat the timber with Teak oil to really bring out the grain and further darken the wood. The Teak oil also provides resistance to UV rays.

American White Oak

Lighter than the African Walnut with a colour range from a light yellowy brown to pale biscuit, occasionally with a pinkish tinge depending on region and site condition in Eastern USA.  Straight grained with a medium to coarse texture. We further treat the timber with Teak oil to really bring out the grain and further darken the wood. The Teak oil also provides resistance to UV rays.


Maple is the lightest in colour of the three hardwoods we use but is also the hardest wearing. It has a creamy white appearance with a reddish tinge. The grain is straight, but occasionally can have a wavy or curvy grain with a fine even texture. We further treat the timber with Teak oil to really bring out the grain and further darken the wood. The Teak oil also provides resistance to UV rays


Timber is a natural product and may differ from the sample images above. Certain species of timber will contain a small percentage of sap and knots in line with international grading standards. We take every effort to select timber to have as few imperfections as possible. From the raw sawn timber coming into our workshops, only 40% of the volume reaches the final finished product.

Manufacturing Process

The rough sawn timber is stored in drying houses prior to delivery to Soundtronics where we further store the timber in a clean dry environment for many more months to stabilise.

The sawn planks are 28-35mm thick so these are planned and thicknessed to remove all cupping and twists to arrive at our standard 20mm thick timber ready for machining.

Depending on the product, machining operations include cutting to size on a panel saw, CNC routing, dowell drilling, routing for corner fixings and slot routing.

Finishing includes sanding, staining (oiling), assembly and packaging ready for dispatch.
