Mixing and Mastering Course | £449
An intermediate/advanced course for producers who want to get to grips with the art of mixing and mastering. Jam-packed full of classic and innovative mixing techniques, tips and tricks shared to you by our established mix engineer instructors. This course is for everything in mixing and mastering you knew a bit about before, but now want to fully understand and make a massive improvement to your music yourself saving a fortune on mix engineers and studio time. It doesn’t matter what DAW you use on your Mac or PC or what genre of music you are mixing; the principles are the same.
This course takes place at the Arthaus in London and the price is £449 with no registration fee. If you miss any sessions due to holidays or illness, we can engineer it so you can come back on a future cycle and catch up. All courses come with extensive notes put together by our expert course developers, and you also get an industry recognised certificate on successful completion.
See what recent learners thought of the course at the bottom of this page. You may recognise a name or two on the list too!
Al Riley, Pete Gleadall and Tom Belton are our mixing specialists. Check them out on our instructors page and Google.
The courses are designed for optimised learning so you take in the content in a day, recap in between sessions at home, and come back to us a week later for the next session of learning. This makes use of an educational practice called The Spacing Effect. Evening courses run two sessions per week for three hours each.
To enrol, call or send us an email telling us which course you would like to do, when it runs and we will organise the rest.

Week 5 – Out Of The Box

You have learnt how to mix records ‘in the box’ (your DAW). Now it’s time to have a go ‘out of the box’ in the analogue domain on a Neve 8078 console, which are considered by many experts to be the the Rolls Royce of desks and the best sounding consoles ever made. It’s not surprising that they are highly sought after.
The studio is a commercial mixing and tracking facility available for hire too. Clients to date include Mark Ronson, Katy B, Noel Gallagher, Burial, Alice Gold, Tinchy Stryder and Jamie Woon. You will be guided through the process of mixing a record in the analogue domain step by step as well as trying out the console, the EQ and all of the vintage outboard toys yourselves. Your mixes ‘in the box’ will benefit massively from this experience alone.

“I attended a music production course at one of the main London DJ schools before doing the mixing course at Garnish. There really is no comparison. If you want to learn to DJ, go to a DJ school. If you want to learn music production, go to Garnish!” Tristen Gleed
“A nice relaxed working environment and detailed, in-depth working practices. I really got a lot from this course and answered a lot of questions I had about sound engineering processes in Pro Tools, especially as I come from a creative background.“ Paul Tilley – Mixing and Pro Tools
“Doing the mixing course is easily the best thing could’ve done to quickly take my mixing skills to where I wanted them to be. Now I understand all about layering, how to find a place for everything, how and when to use compression to make my records sound so much bigger. Knowing how to mix properly has even effected how I make a record in the earlier stages. I can now master my mixes myself for playing out and only use a mastering engineer now when I’m not paying! If you want to learn to DJ, teach yourself or go to a DJ academy. If you’re serious about learning to produce music, go to Garnish” Toby Tobias
“As a songwriter/producer I relied heavily on engineers for recording and mixing if I wanted to get my tracks sounding like masters. I always wanted to do more myself but struggled to learn anything watching an engineer zip around Logic or Pro Tools at 1000 mph! Then I found Garnish School of Sound and did their Mixing and Mastering course. It was exactly what I needed, we covered everything I was unsure of in the past from using buses properly, EQ, audio compression and using specialist mastering plugins. Everything was explained and demonstrated in a way I understood. I never thought I’d ever be able get such great sounding tracks doing everything myself.” Ben Cullum
“I attended at mixing class at Alchemea college before I went on this one. Garnish’s mixing course had better practical learning whereas Alchemea is maybe too much theory not enough practical. Great course, great value, a must for all producers looking to raise their game.” Steve Morant – Mixing
“You are getting taught by teachers who have been in the industry for a very long time and have worked with some amazing people. They are not only showing you how to work the virtual synthesisers, but also giving you tips and amazing advice.” Crysta Healy - EMP and Mixing

“The professionalism and tutoring styles from both Dave and Larry are second to none. Not only did we cover everything on the list, but any questions about other musical topics were covered and answered from the guys. A huge library of knowledge available! Never have I been on a more informative course tutored by guys as experienced as Dave and Larry. If you’re serious about musical production and getting your tracks the quality they deserve, any of their courses should be at the top of your ‘to do’ list!” Pete Waidson
“Wide spectrum of knowledge and expertise in modern music trick-nology. Industry recognised instructors that talk the talk and can walk the walk. Don’t think twice book a course with the G.S.O.S!” Nick Burns – Logic and Mixing
As a Singer/Songwriter, I really was self-taught when it came to mixing, and although over the years I have worked out how to do a lot of things, getting a good mixdown always seemed to be where I was lacking. Trying to get your head around things like compression and EQing when you’ve not had any formal training is hard. Now I have done this course I can now mix my own tracks which I’m loving! Thanks a lot Dave, you’re a Legend! x AiNA - Mixing (Singer/Songwriter and Camden community music production teacher)
“It is the perfect course for mixing, everyone should do this course before starting to mix seriously. Knowledge really is POWER!!!” J Anthony Packett
“I appreciate the personal technique of teaching and the affable and approachable manner of the teachers. The facilities are top notch and the standard of knowledge conveyed is excellent.” James Randle – Mixing
“The teachers and environment are very high quality. I’ve learnt so much and will be booking the EMP course next!” Leighanna Allen – Mixing
“I know your teaching methods are ‘future proof’ and you have some awesome teachers who can express themselves very precisely, perfect balance between theory and practice. It was an overall perfect impression and I wish you and your school all the best.”Stefan Splinter (traveled from Austria) – Mixing
I had been reading manuals, learning the tricks from books, magazines, youtube reviews and much more. All of which are great, but the (Mixing) course I did with Dave took all this and put it into context, whilst making it real and usable straight away. The courses cover all angles of production in multiple DAW formats – a really in depth powerhouse of knowledge that only the traditional sound engineers would share amongst themselves is now at my fingertips…. On top of that, this (mixing) course helped me take all the best and most powerful tricks I picked up while studying myself to a whole new level of awesome! Top notch! – Heady Stepper – EMP and Mixing
