I specialize in mixing rock, alternative, punk, and metal music. I've been in bands playing these genres for 30 years and they are very close to my heart. My goal is to take the tracks that you have recorded in a professional or home studio and turn them into great sounding mixes. Each project gets treated with the same care. I pride myself on having 100% happy and satisfied clients.


Studio Humbucker is made up of a control room and two tracking rooms. I aim to create a relaxed and inspirational environment for you to work in. Having been recording albums as a musician in studios for many years, I know how important it is to have fun and be relaxed while recording. I will engineer and also produce if that is something that you'd like. The last steps would be mixing and mastering, which I also offer as services.

Remote mixing & mastering

You can send me files to have them mixed and/or mastered. I will work on them in the studio. Each day I'll send my work back to you and if necessary make changes based on your feedback. This way you'll be a close part of the process. You will find more info regarding this under "More on mixing and how to send me your files" below.


I work in a hybrid fashion when I mix. I use hardware gear such as compressors and EQ’s, I also make use of my favorite plugins such as UAD, Soundtoys, FabFilter & Softube, to mention a few. I really enjoy working this way, and it gives me a nice workflow, and I get the best from both worlds. I will mix the music you have recorded here, or elsewhere. The internet is a wonderful thing! I can mix your music no matter where you reside. You can send me your files and I will work on it from my studio. Each day I’ll send my work back to you and await your input and make changes based on that. That way you will be along for the ride during the whole process.

Some of the gear and software I use when I mix and track:

  • Mackie HR624 Mk2 monitoring
  • UAD Apollo 8 Quad, 
  • UAD Satellite Quad (x2)
  • DBX 163 vintage compressor (x3)
  • DBX 163X vintage compressor (x3)
  • TL Audio 5051 Valve Processor
  • ART Pro MPA II
  • Softube Console 1 MKII
  • Plugins from UAD, FabFilter, Soundtoys, Softube, Slate, Plugin Alliance to name a few.

Preparing your tracks for mixing
If you are sending me tracks to get them mixed there are a number of things you can do to prepare them. It will save me a lot of time and it will be more cost effective for you and ultimately will make the process much smoother for both parties. Performance enhancement such as drum editing and vocal tuning are not included in the price unless agreed beforehand. 

  • Do not send a DAW session file. WAV files only.
  • Send only the tracks you want to be mixed. 
  • Organize and clearly label your tracks. Make it simple, short, clean and logical. Each track needs to have a unique name that is descriptive of the sound on it and each song needs its own folder labeled with the song name. 
  • Prepend track names with the track numbers. Numbers ensure that all the drums will show up next to each other as will the bass, guitars and vocals, assuming that’s how you have them grouped in your recording session.
  • Turn off processing plugins. If there are certain delays, reverbs, modulation effects, etc. that you have been using and are absolutely in love with, feel free to leave them on the track.
  • Every track should be consolidated from zero until the end of the session. This is to ensure everything lines up correctly once it has been imported. This is critical. 
  • Clean up your tracks if possible. Remove all unwanted noises between performance parts such as breathing, headphone leakage, string buzz, etc.
  • Make sure to create fades and crossfades where needed on all the audio before you export the files and send them to me. This is crucial to avoid clicking, popping or other artifacts.
  • Please be certain that all mono tracks are sent as mono WAV files. Most files will be mono, guitars, individual drum mics, vocal tracks, bass tracks, etc.
  • If possible include a rough MP3 mixdown of the session as a reference and feel free to include any songs from other bands that you want as a mix reference.
  • Please send all files in the same sample rate\bit depth in which they were recorded (usually 44.1kHz\24 bit or 48kHz\24 bit).
  • Pack everything in a zip and send to

Here you can record with your band or do overdubs on the music you already recorded elsewhere. I have a backline readily available for your use, should you choose not to bring your own gear. Drums, a variety of amps, cabinets, pedals, etc. I own a bunch of guitars, both vintage and new. We have everything covered in the backline department to make a great sounding pop, rock, hard rock, metal, project. Check out the gear list under ”Studio”.

My name is Robert Pehrsson. I have been writing songs and playing music for 30 years in bands such as DundertågetThunder ExpressDeath BreathImperial State Electric and for the last eight years Robert Pehrsson’s Humbucker.

I’ve been around long enough to have recorded a couple of albums in the all-analog domain to tape, and then experience the shift towards the digital recording environment. I was always interested in the craft of recording, engineering, mixing and producing, so much I decided to build my own studio, a hybrid between analog and computer-based recording and mixing.

I have also worked as an engineer and music teacher at a culture center for youths. There I recorded and mixed a variety of music every day for 12 years.

Studio Humbucker - Recording, mixing & mastering - Robert Pehrsson

What the clients say

Jobbade ihop kring mix på vårt tredje och senaste album Rambler.
Väldigt nöjda med både samsyn, process, lyhördhet och slutresultatet som verkligen rockade iväg till hundratusentals lyssningar på Spotify och Youtube! Rekommenderas varmt!

Stefan Blomqvist
Black Paisley

Robert Pehrsson har mixat fem låtar åt Deviation Days med mycket bra resultat. Vi lämnade feedback löpande på mixen och fick bra återkoppling på våra synpunkter. Inspelningen fick verkligen en ny dimension efter Roberts mix!

Arvid Engström
Deviation Days

Robert really captured the heaviness and nature of the band when he mastered our latest album. He understood completely our music and elevated our sound to the next level. Letting Robert master our record was the best decision we could have done. If you are looking for a dedicated producer with an expertise in heavy rock music, then Robert is the guy you call first!


Robert is fantastic engineer/producer with great ears and stable hands. He balances the role of being able to both assist the ideas of the band, but can also steer in another direction when needed. Robert mixed and mastered the upcoming Under The Church ep and we´re very happy with the outcome.

Erik Qvick
Under The Church

My band Protector was at Studio Humbucker in the autumn of 2021 to record eleven Songs for the bands eighth full length album. Me and my bandcolleagues Micke, Matte and Calle enjoyed our stay there very much. The studio has all you need for a good recording: good technical equipment, two recording rooms, an engineeringroom and an area where you can relax in between the takes. It is also very close to the subway, if you don't want to take the car every day to the studio. Robert himself is a very sympathetic and relaxed person who, on the one hand, radiates calm, and on the other hand, thanks to his great expertise both as a sound engineer and as a musician, also can give the bands tips for the recordings. 666 thumbs up from Protector to Robert and his studio

Martin Missy

Robert is a genius. He did the mix & master of our forthcoming album and took it to the next level. To be honest every mix he send us was perfect, all ended up sounding killer. Robert achieved exactly what we want it. He have a really good ear and advice, putting the right vibe and good taste. We are more than happy with the end result, totally rips! He's also a super cool person, extremely profesional and friendly. Definitely we are looking forward to work with him again. 

Alex Mendoza

Robert is really professional with a great ear and good advice. We are very satisfied with the result of the mix and we hope to be able to work with him again.


We recently recorded our upcoming album in Studio Humbucker and couldn't be happier with the outcome or with the process. Not only is Robert super skilled and professional, he's also a very pleasant person to work and hang out with. Close to zero time spent on technical problems, extremely good workflow, with Robert finding and solving (or pointing out) problems before we even noticed them ourselves, and a very good communication about mixing and editing, in the studio and also afterwards. Sound is always hard to describe in words, but Robert managed to achieve what we tried to explain to him, and do it very well. Top marks from us and this will be our number one option for recording henceforth.


Robert mixed our, The Revoltas forthcoming release and our single Above! A full-blood professional through and through, Robert managed to elevate our material beyond what we expected and listened to our thoughts with patience. Super happy with the end result, will definently work with him again.

The Revoltas

En studio med ordning och reda - finns det? Ja det gör det - Studio Humbucker!

The Hellacopters

Vi i Cobra Cult fick tips om Robert och Studio Humbucker när vi skulle spela in vår andra platta. Ett av de bästa tipsen vi fått. Robert är grymt proffsig med ett fantastiskt öra och lätt att jobba med. Resultatet blev otroligt bra och vi är mer än nöjda. Rekommenderas starkt, vi kommer absolut att komma tillbaka!

Thomas Jonsson
Cobra Cult

Bästa studion i denna storlek i Stockholm. Expertis om allt som rör rockmusik, och vill du ha något Robert inte kan så lär han sig det utan att knota. Noggrann, lyhörd och punktlig!

Jakob Ljungberg
Second Sun

Robert är gudomlig på det han gör! Mitt band Eternal Evil spelade in sin debut platta hos honom och allt gick utmärkt Dom flesta som jobbar i studios som jag har jobbat med är oftast "Aa cool låt, vi tar den andra". Men Robert är verkligen 100% fokuserad, pluggar sig in i låtarna och ger verkligen bra tips! Efter det här tror jag inte att jag kommer välja någon annan studio för att Robert is the man

Eternal Evil

We hired Robert Pehrsson for mixing our entire new album with Serpent Omega! To be honest the result is beyond all expectations and we are more than happy to recommend the services offered by Studio Humbucker.

Seiðr Jonsson
Serpent Omega

Den Tunga Döden recorded the drums for the debut album in Humbucker. Everything went smoothly and with very good service! Obviously good sound according to what we wanted! Smaller but the nicer studio with the right equipment. Recommended! We'll come back!

Den Tunga Döden

Robert är riktigt duktig och vet vad han håller på med. Proffsigt bemötande och är väldigt mån om att göra ett bra jobb! Rekommenderar honom varmt.

Martin Gut

Rekommenderar starkt! Robert är grymt proffsig och lyhörd.

Joseph Tholl
VOJD, ex Enforcer, Joseph Tholl

Väldigt bra studio. Robert är mycket noggrann och lämnar inget åt slumpen. Mycket engagerad, kunnig, ärlig och mån om att resultatet ska bli så bra. Toppbetyg från mig!

Stefan Rodin

Proffsig, noggrann och trevligt bemötande. Rekommenderas!

Johan Bäckman
Heavy Death, Den Tunga Döden

We recorded our debut album ”Fast Times” with Rokets in Studio Humbucker and the outcome is totally awesome! Robert is a really fun guy to work with, he had really good ideas during the recordings and he was working in a very professional way. We highly recommend Studio Humbucker for everyone who wants to make a great sounding record!

Jaani Kaukonen
The Rokets

Recorded an EP with Hilli & His Henchmen early 2020. Professional and fast service by a very responsive technician who is not uncomfortable recording within a new genre. Studio Humbucker also has a very friendly atmosphere and switching from production talk to just shooting the breeze in general goes seamlessly. Would very much recommend for a personal and professional recording experience.

Tomas Hilli
Hilli & His Henchmen

Robert är grym på alla möjliga vis. Trevlig, snabbjobbad och så blir det ju fantastiskt megabra!

Gustav Wremer
Grande Royale

Vi mixade vår första singel hos Studio Humbucker och vi är väldigt nöjda med resultatet. Vi kände från första stund att vi förstod varandra och att vi kom fram till ett bra Sound snabbt och smidigt.
