5 stars :-)Their last mastering:


Great Job

I've been using Product London for my mastering for quite a while now and I couldn't be happier with their service! Their engineer Ian has been very helpful answering any questions I have and he does a great job on mastering my tracks. I have been using them exclusively and will carry on doing so. My Groovepressure label is making a comeback early 2016 and the first 2 releases (8 tracks) will all have been mastered by Ian. Long may this continue! Get yourself over to the Groovepressure soundcloud from February and you will be able to hear lots of examples of this.

Robin Ball

Pleased by PL's Work

We have almost all our releases mastered by Product London and our artists are always pleased by PL's work. We had once to change a few things and result was approved by the artist. PL is really a pleasure to work with.

Spectrowave Records

What a revelation!

Iain mastered 4 tracks for me after I had to admit defeat. What a revelation! The tracks sound fab They are loud and punchy yet still with great definition and separation of the frequencies and also with a great stereo spread. All in 2 days. I'm delighted and would highly recommend.

Soul Major

Incredibly Perfect

All of the tracks that have been Mastered for me have been incredibly perfect. I have been astounded at the quality of sound that is brought out, the layers all have a distinct quality without overpowering the vocals, which have a depth of their own. I have been very happy and will use you again. Thank you.

Dexter & The Project

Sounds Great!

XLR8R have just put up a free download of my track Fionn which was mastered by Product London and sounds great! Thanks Ian! Go and check it. It's out on vinyl on my Groovepressure label next week.


Really Happy

Iain done a great job mastering my new single, really really happy with it.
Great customer service too and willing to help you get the best out of your track.

Thanks for the great work Iain!


Highly Recommend

I am new in the electronic scene, I knew them by twitter and sent them 3 tracks for mixing & mastering. I think both process are important but the mix process is fundamental for the final result and I am very satisfied with their work. My songs have improved a lot and sound really well.

I am very grateful for their work, profesionalism and good vibes, Iain and his team were receptive to any changes and the songs were delivered on time that they had published. I highly recommend Product London for their great quality and service at a reasonable price. Thanks!!!

Jose A. Núñez


Iain did a marvelous job bringing my music to life. When my next album drops I'll be sure to be sending it over to Product London for the final touch. They have the patience and know-how to get your music where you want it to go. I'm very happy with the results and will be back very soon for round two! Thanks Iain and Product London Studios!

Brian Theoret


Our first song mastered by Product London. Really, really good and satisfied.


I can't recommend them enough

I've used lots of different mastering houses over the years but these guys take it to the next level (pardon the pun). Amazing quality, very reasonably priced and joy or joys don't charge again for running off several different versions of the same mix. This now makes it affordable for me to have everything professionally mastered. I can't recommend them enough.

Jon Dixon

Highly recommended!

I had the chance to play my new track, mastered by Product London, yesterday @ Ministry of Sound, on a big sound system. It sounds amazing. They did a very good job, and the price was reasonable. After I send my track, got it back in less than 24 hours. If I could give more than 5 stars I would. Highly recommended!


Really Impressed

This is the first experience of using a Mastering Engineer on my work. I found Iain through twitter a year ago and couldn't wait to try out their services. I'm really impressed with the output on my track Stabbo the energy of the original loop I created back in April last year was retained in the stunning master I received back. They have managed to bring forward lost sounds and give every part a well defined and full bodied part in the mix. The fizzling hi hats and refined boom of the 808 bass really got me excited when I played it in my car for the first time on the way to ASDA after receiving the file. I listen to lots of music in the car, so if it sounds good there its gonna be great in the club. It's nice and loud without spoiling the intended dynamic range which is what I had in mind. They offer a really quick turnaround and the price is great value. I was able to try it out on the dance floor this weekend and it certainly held its own against all the other commercial quality tracks in my set. Next time I'll be trying out their mix down services too. Highly Recommended! 🙂


Exact sound I was looking for!

I could not recommend more highly that anyone considering it decide to work with Product London!! My album would not be the same without them and without Iain's expertise. He took the time to work with me to get the exact sound I was looking for on each track. Always available, courteous, extremely professional- with the additional (and rare) bonus of the added care that comes from a company who shares your passion. I can't wait to work with them again on my next project! =D

Amber Ladd


Very Impressed, Great sound with elements of the track louder as requested, My go to company for future mastering, even better that they actually really liked the production on my first track, EPIC!!

Victoria Rolph

Clean & Clear

What more could you ask for? The vocals were clean and clear. The instrumentation sounded great. The low end was nice and fat, without swallowing up the rest of the mix. And even though it was much louder, the dynamics and movement of the song were never sacrificed. Everything I was looking for.

Plus the customer service was great. Iain replied quickly to my requests and made my adjustments within an hour of our correspondence. I look forward to working with them again.


Renders Perfectly

I was happily surprised by the turnaround time. The mastering done was really sharped and renders perfectly on all kind of speakers. The sound undergoes mp3 compression really well. Iain MacDonald knows what he's doing and he's fast to answer all the requests. I will definitely work with them again.



Product London Mastering is an amazing company to get your tracks mastered with. The price, revisions, and quality of there work is unbeatable. I've gotten 4 tracks mastered so far, and 3 of them are currently signed. Their mastering service is part of it.

Armando Rosario

Recommend PL unconditionally

This was the first time I sent a song to mastering and I was impressed by the price/quality relation. I can recommend PL unconditionally.

Wolfgang Schwarz

Awesome To Work With

We submitted our song to several mastering services and none compare to PL. Awesome to work with as well. Great stuff!

Frank Garay

Very Impressed

I was very impressed by the quality and quick turnaround, in comparison to others I've used. I will definitely be sending the recordings I'm currently doing to Product London for mastering. Furthermore, I found Iain to be extremely helpful.

Stuart Tabram

Crisp Clarity

As the owner of Swishcraft Music, I've worked with my share of mastering houses in the US for over 25 years. Some have been good some not so good. So after being referred to Product London, I was a bit skeptical. Mastering for Dance Music can be tricky as our artists want crisp clarity and impactful lowed with overall loudness while not peaking or distorting. It's quite an art form in itself. Iain and the boys have been up to the challenge and have not let us down. As long as you let them know up front what you're looking for, they go out of their way to exceed your expectations. In addition, we often work with tight turnaround schedules and we've never had to wait or be delayed.

Matt Consola

Crystal Clear Sound

Faultless. Uploaded and back to me in 24hrs. Crystal clear sound with space and warmth in a track that has a lot going on. Definitely coming back for all future work. Highly recommended.


Super Job

Tania did a super job in pulling together all of the design elements that we had in mind for our logo. She started from scratch with only a description sent to her via email, and effectively created a great signature for our brand!

Fred DiTomasso

Great Service!



Shined throughout

Product London has fantastic customer service. They are very quick, polite, and reliable to get you the tracks you need on time. I had a very tight deadline and they got me my track with time to get a few revisions in! Furthermore, I decided a few days after that I wanted to have my track remastered and they had no problem with helping at no extra cost. Although it took a few revisions, my final product came out a good as I had hoped but it was truly their customer service that shined throughout the entire process. Recommended, I plan to return to PL for mastering and will direct my friends to them as well.


Professional Sounding

I've used Product London for mixing and mastering on a few occasions now and every time they have provided an excellent, fast and friendly service.

I highly recommend using their mastering service to get a professional sounding, full and clear outcome for your track.


Just Amazing

I m really satisfied with the work Iain did, and the service is just amazing!

He mastered this remix for me:


They Don't Over Compress

Having worked in a mastering studio before I was a bit skeptical at first but after a few mastering jobs I’m completely satisfied with the level of quality I receive from product London. They get the volume to the right level, their EQ-ing sounds great and they don’t over compress my tracks.

Dredillah aka Andre

Quick turnaround

Superb sounds i use no one else, very friendly and helpful, quick turnaround

Stu Ward


After being severely let down and ripped off by another mastering firm, we'd given up. After using Product London for a logo, we went to them again to save us.
Wow, Iain really, really took the time to find out what we wanted, how we wanted to sound, along with lots of great advice.
AMAZING communication and we're blown away with the results.
Iain, we salute you. We can't believe you've retrieved our disaster!
Can't wait to work with you again Iain!
Thanks you so so so so so much!

Quick, Professional

I first used Product London to master my own EP in the fall of 2013, and then used them again to master my band's EP in the spring of 2014. Iain is quick, professional, and offers the best rates I've seen which is why I'll continue to use Product London.

Ryan Koch

Great Job

Having never had a track of mine professionally mastered I did not know what to expect. I was extremely impressed when I got my track back. Of course I've looked up how to's on how to master but I can't beat having a professional do it for me. Great job! I can't wait to send over my next track.

Ken Sheldon

Great Mastering Job

I would like to say how good I found the experience of working with Ian at Product London! He's done a great mastering job for me and was really helpful giving me a couple of useful tips. I have just given him my third track to master and I'm sure there will be more.
I am looking for good homes for the tracks so they're not out there to listen to at the moment but I will post again with links when they're available so you can hear the work.

Robin Ball


I cant praise Product London enough.... Their service is outstanding. Nothing is too much trouble and any tweeks or changes to my final masters were done and sent back within the hour. They ALWAYS delivered! Iain especially went out of his way, above and beyond and has helped me and advised me with finding suitable labels for my eps. Product London has a new client for life in me. thanks guys!

Charlotte Moss

Highly recommended!

The sound that product London brings out in your track is unbeatable, I have used others cheaper and more expensive to get a comparison and from the warmth in the bass to the punch in the kick it doesn't compare.

They are such nice people to work with, very professional and very helpful.

Highly recommended!

Thomos Knight

Incredibe Job

I've had an EP mixed and mastered by Product London as well as a DJ mix mastered by them. Iain is a pleasure to work with and very professional. I can't recommend them highly enough for the quality of their work and their responsiveness. I look forward to working with them again.


Simply The Best

I´ve been working with Product London for while and they are simply the best. They give you the attention you require and treat you as part of their family. They won´t stop working on your track until you are pleased with it, and you´ll never feel that they want to finish it quickly because they have other stuff going on.
They are the definition of good work and professionalism, that is why I highly recommend them.

Product London,

Gives you patience and clarity in the business of mastering and promotions. There is never a sense that they need to push something out of the door to get on to the next uncared for project. I highly recommend!


Marcel Humes

Top Calibre

Super fast turn-around. Lends advice on the mix when it's needed. Making mix adjustments has never been a problem, and I don't know of another mastering service of this calibre that allows me to do that for this price.


Highly Recommend

I met Product London via Social Media and have never looked back, they have provided me with a cost effective, quick, no fuss and very professional service/product for my work.

Excellent feedback and guidance has been provided also as the team are heavily involved in the scene, producing Music of their own and also, taking great interest in new and unsigned Artists.

Great for me to keep in touch, from all the way Down Under here in Sydney, Australia.

Would highly recommend them for any Mastering work you may require.

Richard Remedios

Absolutely nailed it!

Absolutely nailed it! Quick on the draw and happy to make amendments. Be seeing you.

Gavin Bailey-Hague

Very Good Experience

As a newbie producer, when it came time to mix and master my first release I chose Product London for the task. I could not be more pleased with this decision! The professional team at Product London handled my track with outstanding attention to detail, and when I asked for a few minor changes to achieve the sound I was looking for it was no problem at all. Iain and the team at Product London have been great, and they have made my track sound amazing. I plan to use Product London for my future mixing and mastering needs based on this first very good experience, and I am happy to recommend Product London to anyone.
