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.

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!

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.
