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.

Great results and a fast turn around. Professional service from start to finish. I can't recommend Grey Mastering enough!

I have learnt so much in the mastering process with Jack. The tracks always come back sounding amazing and weighty. Would recommend anyone to work with Jack.

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 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!

Great to work with, always pays close attention to detail and always delivers a perfect final product! Highly recommend!

Top quality mastering at a very reasonable price for our label DSP releases. Definitely recommend

He gets what type of sound youre after and execute it perfectly and fast. I can not recommend him enough!

Has been mastering my stuff for 7 months now, everything has been top shelf. Couldn’t ask for better and always goes out of his way to give any mix down advice and tips to help get the best out of the track.

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.

Great masters and turn around every time!

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!

Brilliant results and friendly service, I’ve had a music mastered here a handful of times and wouldn’t go anywhere else.
