NAMM 2015 – Electro Harmonix introduces the Deluxe Electric Mistress XO

The classic Mach1 jet flanger

Electro Harmonix’ popular Deluxe Electric Mistress Flanger is now available in the XO version, including several improvements to make it more easy to use for today’s pedalboards. While the inner circuit is still true to the original design, the Deluxe Electric Mistress comes with a EHX9.6-200mA power supply and runs with a 9 volt battery alternatively.

The True Bypass makes sure that your signal chain is not affected when the Flanger is inactive, while Electro Harmonix added a bright LED to the new die-case housing.

The special feature about the Deluxe Electric Mistress is its unique Filter Matrix. When active, it disconnects the waveform modulation from the effect and freezes it to create a matrix of filters, which then adds a special chime to every note in unison.
