Jack is the guy!!

I was looking for someone reliable and talented to master a few tracks and quickly found out he was the one.

As soon as I received the first tracks I was amazed on how they sound perfect, professional, polished and ready for proper soundsystems!

A truly talented artist, you can feel his passion in everything he does.

Also a great human being, kind, helpful and attentive!

I'm glad I contacted him and will happily continue working with him.

This is the guy you are looking for!

Jack has mastered no end of music for me from self-releases on my Bandcamp to over half of my label's back catalogue. Probably getting on for 100+ tracks overall.
Never had a complaint to make. Delivers a top quality service with a fast turn-around and at a super competitive price-point. I wouldn't bother looking anywhere else!

A friend recommended Grey Mastering...

A friend recommended Jack and within the first email I could sense I was working with someone professional, friendly and passionate.
The process flowed with ease and I felt supported and able to ask questions, and feel confident in the process. I am fully satisfied with the end result and will continue to return for all the albums to come.
I feel I've found my forever go-to mastering person and I'm so grateful. Thank you so much!

Jack is the man!

Jack is exactly what you're looking for with someone mastering your music. He understands what you're going for, the vibe you are trying to portray and accentuates it. Great to work with, communicative, gives advise where and when needed. Turns out brilliant sound.

I have worked with him for over a year…

I have worked with him for over a year now. He not only has mastered many of my tracks and they have sounded great but he has personally gone out of his way on multiple occasions to help give me tips, insight, and education which is invaluable. Can not recommend his business enough!
