New studio finished!

Big tones, Toronto studio, Peruvian ears.

What I do
What I do:

From pre-production, recording, tracking, mixing or mastering, I enjoy music and especially the process it takes to finalize it.

I believe each song and record deserves particular attention as it is a work of art on its own, which is why every project is treated in a very unique manner to get the best results.

If you're looking to make your albums sound organic, real and modern, let's chat.

As a multi-instrumentalist I'm happy to work with singer songwriters as well, being able to move the project along with the artist's vision, in collaboration as well with many amazing musicians I've used in multiple occasions. 

Based out of Toronto,  I'm available to mix projects from anywhere in the world, having had the luck to work extensively with bands from Canada, USA, Spain, Peru, Chile and Argentina, as well as tracking out of my studio in the Danforth, or in many other studios in the city. On top of that, my rig is fully mobile, so there's also the option of recording it in less conventional locations.

"I have been in and out of studios for over twenty years, as a player, as a producer, as a songwriter, and I know a great engineer when I see one…Guillermo made it easy for me to focus on the performance and the song without worrying about the technical side of the process.  I had complete trust in his ability to get the best sound and keep the whole session running smoothly. I also found his creative insights and decision-making valuable assets. I couldn't recommend him more highly."

"I am lucky for having worked with many talented sound engineers through the years, and sometimes, even with a few that are very VERY good. I believe that Guillermo is one of the best: 

 he is fast, precise, and he just has great ears!

I always enjoy his work"

I have 20 years of performing, producing, song writing, mixing albums, recording and  doing live sound around the world. 


I emerged from the Peruvian punk rock scene of the early 2000s, with a DIY approach that allowed me to play countless shows, organize festivals and work as a sound engineer for several bands at a local studio in Lima, as well as doing live sound.


After a 2 year period at The Banff Centre, where I worked alongside great artists and producers (Jane Bunnet, The Bad Plus, Joni Mitchell) at the state of the art facilities in the heart of the Canadian Rockies, I moved back to Peru where I toured as the Front of House engineer for Adammo (Latin Grammy nomination and MTV Latin America Award recipient), mixing shows with audiences of up to 120,000 people. 


At the same time I had the pleasure of mixing shows as a freelance Front of House engineer for artists like Joey Cape (Lagwagon), Mike Herrera (MXPX), Youth Of Today, and many more.

In December of 2010, I moved to Toronto, Canada where I started gaining a reputation as a mixing engineer and musician, sharing stage with Measha Brueggergosman, The Honeyrunners, Pat Robitaille and Cayley Thomas.

Before opening my own studio in the city, I was lucky to have taught at Recording Arts Canada, toured worldwide with The Sadies and engineered out of Revolution Recording for 2 years.

In 2014 I decided to continue as a freelancer and work now from my studio in Roncesvalles, where I keep having fun making records, songwriting for TV and Cinema, as well as mixing and recording for Youtube with credits including "Dallas and Robo" and "Dreaming of A Jewish Christmas". The new and improved location is now in the Danforth.

I have the luck to have a seat on the board for Literal Change. A non-for profit organization which focuses in reducing illiteracy numbers in detention centres and penitentiaries. Through social labour I believe we can make a better community for everyone.
