On piano keyboards, the reed plates for black keys are usually located closer to the filling than those for most white keys. On chromatic button keyboards, two reed sets are typically distributed across 3 or 2 reed blocks (the latter solution often requiring particularly slim reed plates). The cassotto effect tends to be stronger the further the reed plates are from the filling.

The firm Öllerer built a diatonic instrument with cassotto without register switches and two 8' (M) reed sets. Making a cassotto for diatonic instruments is quite more difficult due to the different reed plate arrangement. For chromatic accordions, a cassotto does not perform equally in every tone.

Cassotta (374 + 414), also known as "Klingenthaler
Spezialcassotto" or "Füllungscassotto". In those models the reed blocks are arranged in one plane like with ordinary accordions. The effect of cassotto is produced by a small "canopy" ("Vordach") under the treble hood forming the cassotto hollow. An

The effect of a cassotto is less pronounced with various instruments. The impact is therefore also not commonly evaluated. An individual assessment is required for each instrument. Oftentimes the cassotto sounds will be described as warm and chubby. Due to the filter effects, there are few strong,

Usually only some reed blocks are placed in the cassotto enclosure, typically for low reed sets 16' and/or 8'. The remaining treble reed blocks are mounted straight.
