Very good sound quality, clear sounding bass. The main speakers on the sides allow a better distribution of the sound.
The weight makes the equipment not very practical to move it.
I have experience of playing a Viscount Chorum 20, and the capacities of this one that by being portable are not inferior to it well worth the investment. I like the versatility of the transposer, it allows to connect a pedal of volume and a pedal growing, that is an advantage in a portable organ. In addition they disclose 4 styles of organ sound that are a plus. I have used it in churches and it has a comprehensive sound, which does not require external amplification.
