"John helps my compositions and arrangements reach their full potential with his unwavering attention to detail. He’s attentive to what I want for each project and keeps me involved in the process. Without fail, the end result always exceeds my expectations."
"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."
"Having my tracks mastered 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!"
