Mad Professor announced an updated version of its Electric Blue Chorus, the Electric Blue II Chorus and Vibrato pedal, an all-analog modulation stompbox built on bucket brigade technology for a vintage effect¹². The original Electric Blue was just a chorus; the MkII adds a Tone knob and a newly designed vibrato effect, extending the functionality of the original¹².

The pedal is housed in a pedalboard-friendly package with a simple-to-use, yet versatile, control layout³. The enclosure features four knobs, Depth, Speed, Mix and Tone, plus a mini-toggle for switching between chorus and vibrato²⁴.

• Depth, Speed, Mix and Tone knobs for the core modulation settings²
• Mini-toggle for choosing between chorus and vibrato modes²⁴
• Tone knob for a range of colors from warm/vintage to bright/modern¹
• Mix knob to combine the wet and dry signals⁵

In chorus mode, the pedal is designed to deliver slow, traditional chorus effects and faster faux-Leslie type effects and everything in between, with the Speed knob affecting several parameters to optimize the delivery at fast and slow LFO settings¹. Guitar Player reported that the chorus mode looks to deliver Leslie-esque effects plus richer, more luscious chorus sounds⁵. The vibrato is a fully original design, described by the builder as "the most expressive vibrato with expanded vocabulary"¹. Gearnews noted that the dedicated vibrato circuit was designed from scratch rather than tacked on, and that it can function with distorted tones⁴¹.

Said designer Jyrki Rahkola, the Electric Blue II seeks to provide "analog modulation like never before"³. Delicious Audio described it as an "innovative and beautifully complex all analog bucket brigade design," with vintage technology and modern engineering for what the maker calls the most organic and purest analog tone and ultra-quiet performance¹.

The Electric Blue II was priced at €170 (approximately $205) and was due out in April 2021, with MusicRadar reporting it should be with dealers mid-April⁵². Delicious Audio added the pedal to its list of Best Chorus Pedals¹.
