Quote To say FURNACE is hot would be cliché’, but damn – this little plugin delivers beautiful warmth and overdrive across three killer analogue flavours: Tape, Transformer or tube. Crank the input, switch modes and instantly dial body, colour and crunch into instruments, vocals or full mixes.

Quote Furnace is now a permanent fixture in my mix templates, living on my instruments, vocals and mix busses. It is a versatile, yet super quick and easy way to add harmonic density, character and life to a mix. Highly recommended! Plus, the presets kick ass!

Designed in collaboration with

The Audio Firm

Mix and Mastering engineer Sean J Vincent has collaborated with Fazertone to create his ideal saturation plugin.

From subtle warmth and gentle compression to rich harmonics and aggressive drive, Furnace lets you add cohesion to your mixes, enhance individual tracks with analogue character, or creatively shape your sounds with these three classic saturation flavours.
