I'm sure it probably won't compare to the Vermona in terms of build quality. But from the videos I've watched, the DB sounds comparable. I owned a DRM-1 mkIII for a couple of years. It's built like an absolute tank. I loved the high-hats, snare, and clap. But some of the sounds were simply too metallic and zappy for my tastes. The kick was... okay. But a lot of people love 'em. This DB sounds very similar to the DRM-1 mkIII, imo. But much cheaper and with more features. 17 voices, sequencer, etc. I think if someone wants "that type of sound" then these two will be up for a duel. Buyer will have to decide based on build quality, extra features, price, etc.
Maybe in a few months somebody could buy the DRM-1 used and this DB used. Sequence the DRM-1 with the DB and have a fantastic time! I think they would blend really well.
Damn, now I'm thinking about buying another Vermona. I still have the desktop rack I placed the Vermona in. I had a Push down below it to sequence. Move the Push out for DB, layer the sounds, and you have a cool desktop setup with tons of hands-on tweaking and fun.
