 Although the band produced the album, Pekka stated that Antti was the main producer since he was present at every step of the production, including mixing and mastering. Because they were comfortable self-producing on all their previous albums, they refused to bring in an outside record producer for 12 Gauge. "This concept has worked for us since the beginning and we just want to trust it. Everything goes easy with this setup and we don ’ t want any extra risk factors". Mastering for the disc took place at the Cutting Room in Stockholm, Sweden.
