At the core of Eve’s mastering studio is the incredible BBC ‘Kingswood Warren’ Type B valve mixing console — also known as the Enigma Machine.
What is the Kingswood Warren?
Originally built by the BBC in the early 1960s to test loudspeakers, the Kingswood Warren is a seven-channel vertical valve mixing console. It has been lovingly restored and is now the only one of its kind in the world.

What can the ‘Enigma Machine’ do for you?
“The sound it gives is perfect for the digital age. It smooths sharp high-end frequencies without losing clarity, and adds a vibrancy to the mix. You get masters with more depth and richness — more cohesion, more three-dimensional space. Plus, using gear once handled by Radiophonic Workshop pioneers? That’s a real buzz.”
— Jim Spencer.
Jim sees mastering with the Kingswood Warren as a mix of secret weapon and living history.
