The Electro Harmonix Neo Mistress is simply a compact, professional flanger. It is impressively simple to operate, versatile, and it has some very powerful features. The two knobs on the front provide Rate (the speed of the LFO sweep controlling the flange) and Feedback (the width and intensity of the effect), while the traditional stomp switch alternates between true-bypass and effect mode. There is a status LED too, which not only lights up when effect mode is on but goes from green (high) to amber (mid) to red (low) to show where the flanger is at in its cycle.

If you set the Rate control below 11 o'clock (shown by the star symbol beside the knob) you access the 'Filter Matrix mode', which gives you manual control of the flange, you can then go between 11 o'clock and all the way anti-clockwise to manipulate the effect manually. If you push the Feedback control beyond 3 o'clock you start getting lots of extra harmonics, almost as if the flanger is generating its own sounds, which is perfect when you want to take your flange to the next level.

While on Filter Matrix mode, you can also leave it at a single setting and manipulate the feedback knob to get some amazingly unusual sounds. EHX suggest trying to find resonant bell tones and steel drum like tones, but there is a huge scope for experimentation beyond that. The Electro-Harmonix Neo Mistress is exactly the kind of pedal EHX are famous for, featuring subtle and high quality effect sounds through a simple interface, while simultaneously giving you that bit of extra control and creative freedom that most other effect manufactures seem to ignore.

Power it with either a 9V battery, or a 9V power supply. This compact pedal will easily fit into your pedal board and it is definitely worth having in your arsenal, especially if you want both classic 'go-to' effects plus a bit more scope to experiment with.
