DB3 exists in 2 versions: the expander and the keyboard version. The latter has more of a keyboard with 61 keys like waterfall (near the keyboard of a "real Hammond"), if not the specifics of the 2 versions are the same.

DB3 is a clone of the Hammond organ, there is therefore no sounds of organ tone wheel, adjustable (like on a B3) with 9 drawbars (drawbars) present on the dashboard.

UTILIZATION

Use of DB3 is a breeze: no hidden menu, everything is accessible and intuitive. Sounds are easily configurable and memorable, as the manual (English or Italian), it is almost superfluous.

SOUNDS

When playing in blues bands, rhythm & blues, soul and even jazz, we definitely need to B3 sounds authentic and realistic. At first glance, the DB3 fills out these features: basic sounds, without the rotary speaker (Leslie) are very well reproduced, and can quickly take to Jimmy Smith (organ jazz sounds are really realistic).
The effect Leslie (Rotary Speaker) leaves a little to be desired, it is preferable to use an external leslie for the big sound (I use a small personal Boss RT-20, and it does)

OVERALL OPINION

I use the DB3 2 years now in version keyboard, and it's really comfortable to play on this type of keyboard, the look is vintage wood (good quality, ideal for waterfall keyboard glissando), the drawbars provide sensations game previously absent on other synths and sound modules). We are almost at the controls of a B3, but lighter and cheaper.

The only defect of this organ, Leslie is the effect that should be better. Hence the need to obtain either a real Leslie (beware of lumbago) or a good emulator Leslie (Boss RT-20, Korg G4, H & K Rotosphère).

At the portfolio level, nothing to say, the DB3 is 3 times cheaper than a Roland or a Korg CX3 VK8.

In summary, for a broke musician (redundant) fan of vintage sounds of the Hammond organ and who does not want to get a backache by carrying a real B3, the Viscount DB3 is ideal.
