Yamaha BK-5B is an electone organ with three keyboards and a pedalboard. It has a variety of features that allow you to create and play music.

With 6 voices on the upper manual, 3 on the lower, and 2 on the pedals, you can create a rich and full sound. The vibrato lever adds depth and expression to your playing, while the percussive effects provide subtle but important shading.

The reverb effect makes your playing sound full and rich, and the reverb balance control lets you adjust the balance between the upper and lower manuals. The expression pedal gives you control over the volume of each note or phrase, and the tremolo effect adds a touch of excitement to your playing.
