Having mastered my tracks by John is not only a technical decision. Besides bringing the music up to professional standards he also has an incredible gift (and ear) to preserve the musicality and dynamics within. Definitely my first choice when it comes to mastering! Dirk Ehlert

These days with the Internet offering all these different automated “Mastering” services it’s just nice to have someone like John. He’s the real deal. Incredible ears and incredibly skilled. I trust his judgement implicitly and he’s always there for you should the need arise. He’s also more than willing to discuss his process and exchange ideas. That to me is crucial. He’s the man and his track record speaks for himself. Stephan Baer

Working with John over at Musiklab has been a fantastic experience from day one. Attention to detail, fast turnaround, valuable insight and feedback but most importantly, absolutely fantastic sounding masters. He’s always gotten the most out of our mixes: every detail comes to life with clarity and vibrancy while staying true to each individual track’s sound no matter the style of music. Helluva a mastering engineer this guy! Guillermo De La Barreda | Dos Brains

What a treat to have your mastering engineer send your work back to you, all polished, and when you listen you just go, “ahhhh…. that’s it!”. It’s like a cool drink of water on warm day, or a mug of steaming tea on a chilly one. Hits the spot. Emily Jones

Want to say a big thank you John for your brilliant mastering of the ep. It was really great to work with someone who took a genuine concern with our tracks offering us help and advise and consulting with Stephen, the mix engineer too. All this was above and beyond the mastering service we expected. Thanks again. Was a pleasure to work with you and look forward to the next project. Katie Morgan & Brian Clayton
