I'm Tom MacLean, founder of Twelve Tone Studio. When I'm not working as a mixing engineer, I'm a musician, composer and producer.

I started out in the music world back in 2005 after finishing a Jazz Guitar Diploma at Trinity College of Music. My first 'proper' band was To-Mera, a progressive metal band for whom I played lead guitar, wrote and recorded 3 albums (2 for Candlelight Records), and opened for bands like Dream Theater, Pain of Salvation and Emperor.

From 2007-2013 I was the bassist for epic proggers Haken, with whom I also recorded 3 albums (2 on Sensory Records, 1 on Inside Out) and played some cool tours and festivals.

Since stepping back from the touring life I have worked on a number of projects, including a metal project called Psion, and have gradually turned my focus towards the production aspect of music. I have completed my professional certification in audio engineering from HOFA-College in Germany, where I studied under a number of highly experienced tutors in the rock and metal scene, including Dennis Ward (Angra, Gus G, Pink Cream 69). I continue to hone my skills as a member of Jordan Valeriote's (Intervals, Auras) exclusive Syndicate group of mixing engineers.

Helping musicians achieve their dream productions is my passion in life. For any questions you may have about how I can help you achieve this, please leave me a message in the contact form below.

Mixer Desk


Whether you've recorded your tracks in a professional studio or in your bedroom, I am an experienced mixing engineer who can turn your raw recordings into exciting, dynamic, label quality mixes. I specialise in a range of styles within the rock and metal sub-genres, from ambient post rock to full-on death and black metal, incorporating both modern and classic production approaches. But, more importantly than that, I have the breadth and depth of experience to make the mix sound how YOU want it to sound.

My mixing packages can also include the following additional services:

- editing and comping of vocals, guitars and drums;

- guitar/ bass re-amping;

- drum sample replacement;

- adding orchestration, synths or special FX;

- session guitar and bass recording.


I am passionate about making amazing-sounding music with creative individuals, and endeavour to be affordable to all. Whatever your budget,  I can offer a package for you.

If mixing is the creative side of music production, mastering is the technical side. Essentially, it is the process of ensuring that your music sounds as good as possible across a range of listening devices (HiFis, iPhones, Bluetooth speakers, car systems etc). 


If you've mixed your music already, I can help add the finishing touches to prepare your music for release.

Mastering involves reviewing the mixing and addressing any imbalances or issues in the following areas:

- general clarity and separation;

- EQ;

- dynamics;

- loudness. 

Whilst mastering is less of a subjective process than mixing, I still master exactly to your requirements. You want it loud as hell? No problem. Or you want to keep it punchy and dynamic? We can do that too!

I can master exclusively for streaming/ downloads, or for CD and Vinyl release as well. 

You can read more about my approach to mastering here.

I am based just outside of London and can offer recording space in several professional studios in Surrey and Berkshire, including (but not limited to) Pyramid Studios and Spiral Studios.


If you don't have the budget to hire a recording studio, or don't live in my area, I offer an affordable alternative: the mobile recording studio!

I can bring my recording equipment to a convenient location of your choice, from rehearsal studios to garden sheds!


Or if you prefer the DIY option, but don't know where to begin, I can advise you in how to get your own home studio properly set up for professional quality results, whatever your budget!
