TK Audio Transformer

Transformer is a flexible colour box built for tracking, mixing, and adding real analog attitude to in-the-box productions. It combines several harmonic stages with a transformer-coupled Class A output, letting you move from subtle warmth to obvious saturation, weight, and vintage character.

The first section offers three distinct flavour paths: transformer saturation for extra low-end harmonics and punch, a passive saturation circuit rich in odd and even harmonics, and an active germanium stage with a gritty vintage edge. A blend control makes it easy to dial in exactly how much colour you want, from gentle enhancement to full-on texture.

The second section adds a transformer-coupled Class A stage with a punchy British-voiced 70s feel. There’s also M/S processing for treating mid and side content separately, plus illuminated switches and detented controls for fast, repeatable recall.
