Jeffrey de Gans

Da Goose Music is driven by Jeffrey de Gans (Gans is dutch for Goose). Jeffrey was born in 1971 and was obsessed with music, sound and technique from the day he was born. At the age of 10 he started messing with tapedecks, mixers and turntables while playing his sisters disco records. Later he had his own (illegal) radio-station, worked for a drive-in-show, worked for several radio-stations, produced and released over 70 vinyl-records and played worldwide (and still does every now and then) on a zillion parties as a DJ.

espresso naked filterOne of his passions is making espresso; always fine-tuning the machines to make the perfect espresso. This is something that can be found back in his mastering skills; always looking for the best and even push it just a bit more.

Da Goose Music was founded as a music-production company in 1996 and Jeffrey’s first real mastering-job dates back to the end of the nineties. Needless to say that he has a lot of experience, a great set of ears and serious knowledge of what he is doing.

What about the eco-friendly-studio logo?

ecostudioWe believe in the fact that a better and healthier environment starts with yourself. That is why we have taken a lot of care about how to deal with the energy consumption.


  • Da Goose Music runs on 100% Solar-power!
  • 8 massive solar-panels combined with a Mastervolt (hence the name) power-inverter.
  • Lightning is done with energy friendly led-lights (also in our private-house)
  • In the studio roof we installed a sola-tube daylight system; less artificial lightning needed.
  • Studio isolation with mineral wool which is soundproofed, but also well isolated when it comes to temperature.
  • The roof is covered with sand and stones; grass and weed can grow freely forming an ecological isolation.
  • Because of the isolation, no energyslurping airco is needed and econoheat heater in the winter.
  • Equipment not in use is switched off.
  • Amplifiers are Class-D which are known for extremely low power consumption.
  • Computers make use of SSD disks and all screens are LED screens with standbykillers.
  • For data we use a synology NAS with eco hard-drives with automatic powersave mode. The NAS device is automatically switched of during nighttime.
  • To monitor the energy consumption, we use a Wattson energy monitor.
