I'm Tom MacLean, founder of Twelve Tone Studio. 

Having started out in the music world back in 2005 as the guitarist for progressive metal band To-Mera, and later the bassist for epic proggers Haken, my experiences in recording and co-producing 6 acclaimed albums and several EPs within the genre led to an insatiable desire to understand more about the technical side of music production. In 2015, I decided to study the arts of mixing and mastering more seriously, and have undertaken audio engineering training through HOFA college in Germany (under tutors such as Dennis Ward), as well as personal training as an exclusive member of Jordan Valeriote's (Intervals, Auras, Silverstein) Syndicate programme. 

Helping musicians achieve their dream productions is my passion in life. I am experienced in many production styles, from cutting edge progressive metal to vintage classic rock. 


For any questions you may have about how I can help your music sound the best it can, please leave me a message in the contact form below.

I know that choosing the right producer or engineer to work on your production is a big decision to make. There are so many factors to consider and you probably have some questions about whether I'm the right fit for you, or about how the process would work. 

To help make the decision easier for you, I have prepared some responses to some typical questions that prospective clients have tended to ask before we've agreed to work together. 

You can find them on this page.
