Master Your Music

Mastering is the last step in the music production process. The final chance to improve and quality check your music before everyone hears it.

A mastering engineer gives you unbiased professional feedback of your music and a clear perspective with a fresh pair of ears.

My main aim? You completely happy after I’ve taken your mix to master.

John is an incredibly sensitive musician and this is one the qualities that make him a fantastic sound engineer. He has a talent of intuitively understanding exactly what a track needs (be it in mixing or mastering) and he hits the nail on the head every time! He is fast and reliable while maintaining a very high-quality standard and I could not recommend him enough.
