Mad Professor Deep Blue Delay Handwired Pedal

A handwired version of a modern delay classic

The Mad Professor Deep Blue Delay Handwired brings the beloved Deep Blue Delay circuit into a premium, handwired format built in Finland using high-quality through hole components, Alpha potentiometers, and Switchcraft jacks.

The Deep Blue Delay is known for its warm, natural repeats and simple, musical design. It keeps your dry signal fully analog and untouched, while the delay side delivers rich, organic echoes reminiscent of classic tape and analog units. There is no aggressive noise reduction or overly bright digital sheen. The repeats sit naturally behind your playing and decay in a smooth, musical way.

With its intuitive three-knob layout, the Deep Blue is easy to dial in. It covers everything from tight slapback to spacious ambient textures, and it works beautifully with both clean and driven tones. It can be placed in front of an amp or in an effects loop without losing clarity or feel.

This handwired version elevates the original design with premium construction and road-ready reliability, while preserving the straightforward character that made the Deep Blue a staple on so many pedalboards.
