Introducing the Casio CTK-240 portable keyboard

The CTK-240 comes with 49 standard keys (four octaves) and is perfect for combining fun with serious learning. 100 timbres, 100 rhythms and 50 songs all lend themselves to instructive music lessons. Where the music is! Even the design of the CTK model is extremely impressive: slimline, slender and black - it is a beautiful piece of technology.

Please note, a power supply is not included and must be purchased separately. We recommend an EPA95100 9.5V adaptor, or 6 x AA batteries.

What we think of the Casio CTK-240...

As a starter keyboard this model offers exceptional value and if you are buying in bulk offers real savings over many competitor products. The CTK1100 offers a much improved specification and is slightly cheaper, so I would purchase that instead. However at this price point the CTK-240 is hard to fault, especially if space is really limited. Do remember to purchase a power adapter if you do not want to rely solely in battery power.
