Mad Professor re-launches Handwired Series with three pedals

August 26, 2025 · 2 sources

Mad Professor has re-launched its Handwired Series with the Deep Blue Delay, Royal Blue Overdrive and Sweet Honey Overdrive, all available for pre-order from the Mad Professor Webstore, with new artwork and shipping planned for early October¹.

The Royal Blue is a Blues Breaker style overdrive, the Sweet Honey is an overdrive and the Deep Blue is a digital delay¹. The Sky Blue Overdrive has yet to be re-issued, Guitar Pedal X reported¹.

A later listing for the Deep Blue Delay describes it as the same natural-sounding digital delay with an analog direct path, with no filtering on the dry signal and no noise reduction circuits on the decay². Its controls are Level, Delay and Repeat, with delay time from 25 to 450 milliseconds, one repeat at minimum feedback and infinite oscillation at maximum². The pedal is handwired with through-hole components, Alpha pots and Switchcraft jacks, in a custom sheet metal box with top-mounted jacks, built in Finland and covered by a lifetime warranty, according to that listing². It states that a factory-built, non-handwired version is available at about one third of the price².
