Mastering Engineer

Super talented and easy to work with! I'll definitely be working with him again in the future! My masters sound better than I ever could've imagined.

Beautiful

Great Mastering Engineer!

I am very satisfied with the final mix that Jonas sent me. Also, he assisted me with a pre-mix report so I could refine my track prior to Jonas's work. And that gave me more confidence with the new adjustments (which were delivered very fast).

It was an amazing experience working with Jonas! He has an amazing ear. Most mastering engineers will simply master what you send them and just send it back but not Jonas. He pointed out something in my mix that needed to be fixed! So I’ll be doing much more work with him

Jonas was the nicest person ever. He was very patient made sure I was happy with my project.

Fixed a messed up situation and made a gorgeous, smooth yet loud master for me.

I’ve had the privilege of getting 2 songs mastered by Jonas. His work is amazing but it’s his humility and professionalism that really stood out!! I recommend him to anyone looking to elevate their music. And I’m definitely going to work with him again!!!

Omg I could cry, what Jonas did with my record is absolutely beautiful! Super professional and efficient, I think he returned the finished product in less then 12 hours.

Jonas did great, detailed work on my master with very fast turnaround- glad I picked him!

JONAS! The Man knows what he's doing! First I Really appreciate how humble this guy was and how he helped the mix of my song In which he provided a service to help my song reach the full potential and it did on the first try! He's Very knowledgeable with mixing. He then Mastered it beautifully! Really appreciate his time and quality of work! He also gave me very valuable information on Mastering which will help in the distribution process as well very much appreciated. I will be back

Jonas was very professional from start to finish and super easy to work with. His mastering spoke even higher volumes and added that final touch that my tracks needed. No revisions needed. Amazing engineer!

so fast and perfect output. I hope work again with him later

Great experience! Jonas was super easy to work with- the master came back quickly and with impeccable quality. Highly recommend!

Jonas immediately knew what I was looking for out of my master, and was able to work efficiently and effectively! Super solid working with him, highly recommend!

Jonas provided a beautiful master. I look forward to working with him again in the future. thank you!

Jonas was extremely understanding, patient and professional throughout my entire time working with him. I spent a good amount of time looking through different engineers and decided to go with Jonas and I am amazed with how he was able to take my song to a different level. I will definitely be working with him again and advise anybody who happens to come across his profile to do yourself the favour and choose him to work on your next song!

Working with Jonas was a dream - he was efficient, professional, and most importantly, delivered a freakin' amazing master. I'd recommend Jonas to anybody looking to take their song to the next level.

Very happy with the finished product. I highly recommend. I think I got my truck back in about 24 hours which was nice. Thanks again

DO YOURSELF A FAVOR AND BOOK WITH JONAS! Not only did his masters bring new life and loudness to my tracks than before, but he was also EXTREMELY accommodating, helpful, and patient! So happy I found him and looking forward to working with him again!

Jonas absolutely killed the master for our first single. Super flexible, easy to work with, fast and great communication throughout. Instincts are dead on and really brought the song to life in a way we didn't think was possible. 1000% would recommend him and will be our go to for future releases.

Super professional and excellent work. Got everything I asked for. Jonas’s mastering quality and talent are elite.

Jonas is always helpful for whatever I need and he understands the whole music production from songwriting to mastering that is why I end up coming back to him every time!

Another great master from Jonas. He really has a remarkable ear for delivering a sonically pleasing and dynamic finished product.

First time working with Jonas and it certainly was a pleasure. A genuine, professional who's turnaround was lightning speed. We will be using Jonas regularly for our masters. Highly recommend him!

Super Good!! Very patient engineer.

Jonas is my go-to. Very professional and always knows how to give the track that boost while preserving dynamics.

Jonas W.K. is an amazing professional, communicator and engineer!

Highly recommended!

Jonas is picky and that’s a good thing. A lot of guys on here told me my song was ready for mastering, not Jonas. He challenged me to make my mix better and though it was more work, the end result was stellar. Jonas really cares about ensuring the product is quality but most importantly what you want! We did multiple revises and when I asked him to tweak something he was more than happy to. I’m am so psyched about the finished product and I will definitely work with Jonas again. He helped me

Jonas came back to me super quickly and the turn around is super fast- he mastered an instrumental for me as well as the main version free of charge which I really appreciated!! Everything was high quality and sounded great.

Dope

Great Sound and great guy! Very accommodating!

Jonas was very friendly and professional, helping me to get the level of quality I wanted.

I will definitely work with him again.

Always delivers an awesome master. Highly recommend!!

Jonas did an incredible job on the master of my new song! He gave detailed information on my original mix which optimized the dynamic range and clarity of the finished song. He responded quickly, was professional, and I couldn't be more pleased with the quality of his work. I will definitely be working with him again in the future!

Jonas was very responsive, professional and helped me get the tone I wanted from my master. Would definitely work with him again.

Love what Jonas does with my mixes and always great to work with.

2nd time working with Jonas. And once again, I'm more than pleased with the result and mix feedback. His attention to detail is awesome!

Very understanding and tech-savvy

Jonas brings out the very best elements of your track. He has a great combination of talent, skillset and creativity when it comes to production and mixing. Looking forward to working with him again, and would highly recommend him for anyone who wants to create or bring out the best of their craft.

I couldn’t be happier with the end result! Just amazing!
Thank you so much!

Jonas is the absolute best. Jonas took a track I had been touring with for a little while, and he completely re-imagined the mix to a whole other level. He's patient, professional, and insanely talented! He is truly the best and I highly recommend!!!!

Jonas is my only choice ! My project was completed on time and with the upmost detail and precision. His creative input also helped me to push my project further than I ever imagined. His skill set and ability across many genres are priceless. Adding to his talent as a producer with further skills of the best mix and mastering l have found. I will only use Jonas moving forward for all my music needs.

Jonas has also mastered "Look At Who I Am (BLKZEN Remix)" for me. Check out the song if you wanted to hear his work and quality!

Jonas is the most skilled/talented/humble/hardest working/nicest guy I have ever met. He has mixed/mastered my original song "Look At Who I Am (Feat. Lu Alex) and I am going to ask him to be a part of my team and mix/master all my future songs for me. I do NOT want many people to know him because I want to keep him on my side.. lol Not going to lie he is absolutely 100 stars!

Jonas was super professional, amazingly helpful, and responded to all my questions with my project patiently and thoughtfully! I've worked with other mastering engineers in the past and Jonas is by far the best in every aspect. He had my project back in no time, but with no sacrifice to quality as my song sounded incredible after his mastering! Looking forward to continued success with Jonas!

Jonas, the most kindest and unbelievable talented producer/songwriter! Jonas has written and produced songs to a pop artist that I manage. His unique, distinctive style really makes the records he creates stand out. His skills in mixing are outstanding, not to mention vocal editing! Always such a pleasure to work with him. A true gem :)

Jonas has mixed many songs for me. He's a a top notch engineer who has the highest quality gear, a great ear, and a true musical sensibility which gives him a unique vantage point when mixing. He consistently delivers the highest quality and freshest sound on every record!
