Welcome to Da Goose Mastering

My name is Jeffrey de Gans and I am the proud owner and head-engineer of Da Goose Mastering. My studio is located in Hendrik-Ido-Ambacht, in the Rotterdam area, the Netherlands. This is where I dedicate my life to give your music the final touch it deserves.

With kind regards / Met vriendelijk groet,



I offer outstanding mastering to bands, musicians, labels, studios, and producers. 

I use only the best analog hardware and digital software to improve the clarity, definition, and depth of your precious recordings.

Other services

Besides mastering I can help you with editing, restoration, transfer and (mix) advise. 

If you are looking for inspiring lectures or seminars about mastering or music and audio in general, i’m ready to help you.

Stem Mastering

With stem mastering individual audio stems are grouped together for independent control and processing. 

Most of the times stem-mastering is not needed and it will not make your master better. The max amount of stems I will work with is five.


I don’t offer mixing-services myself... but..

If you are looking for someone serious to do your mixing, I have some awesome mixing-engineers in my direct connections which are pleased to help you!

Please contact me and I will bring you into contact with the right person for your project.

“Mastering is the final step before your music is released to the world. I take that very seriously.”

Please contact me first before deciding to order stem-mastering. Most of the times stem-mastering is not needed and stereo mastering will work fine.


I prefer the use of the online order system for per track mastering.  

In case of an album or other specific wishes that will not fit the online order system, please provide me with all this information: companyname, contactname, full adress, VAT number and emailadres. You will receive an agreed upon invoice and after the payment is payed in full, I will start mastering.

All prices are excluding 21% VAT.

    This is fantastic!
    Thank you so much Jeffrey. I am excited to work with you again.

  • Ed Dejon

    Goedenmiddag Jeffrey, hij is weer lekker hoor. Wat een heerlijk laag 😍.
    Dankje wel🙏🏻.

  • Wesley Steinfort

    Bedankt weer! Het laag klinkt inderdaad lekkerder en warmer, de vocals klinken veel minder scherp en daardoor softer, precies wat we zochten! Bedankt voor je expertise en opmerkingen, fijn, bedankt!

  • Ritchie

    IK BEN BLIJ! Haha, heel dik Jeffrey, thanks alot! Ik hield hem even naast mijn 'eigen' master. Meteen duidelijk waarom je dit bij jou moet doen en vooral niet zelf, hahaha!

    Hey Jeffrey! Thanks so much for knocking out this master! I love the way it sounds. I love the loudness etc. Still super dynamic and i'm able to hear all the layers clearly. Thank you as always!

    I wanted to play the tracks on different devices before responding but now I can safely say they sound great, I'm very pleased with them!

  • Daniel

    Masters zijn goed ontvangen en iedereen hier is su-per blij met het resultaat. Ik had het ze al gezegd dat het in orde ging zijn maar de masters hebben ze echt omvergeblazen ;) Thx! Ik kijk er al naar uit om de volgende releases ook samen op poten te zetten, je hoort nog van ons.
