A press-and-hold option on the second (FX Select) footswitch toggles between chorus and flanging, and you know where you are because the flanger legend is backlit in flanger mode.

Speed and Depth knobs adjust the effect, while an Intensity knob adjusts the dry/wet balance between the input signal and the effect, but also acts to increase the feedback in flanger mode for more of a classic metallic flanging sound.

Both effects exude quality and are clear, detailed and sparkly. And should you choose to use the stereo outputs, there's a wide stereo effect with some panning movement in it.

If you add an Aero to the mix, apart from instant remote switching from a chorus to a flanger sound, there's plenty of opportunity for some animated effects, such as ramping up the flanger speed for a ray-gun effect - limited musical use, perhaps, but some will like it.

Trevor Curwen has played guitar for several decades – he's also mimed it on the UK's Top of the Pops. Much of his working life, though, has been spent behind the mixing desk, during which time he has built up a solid collection of the guitars, amps and pedals needed to cover just about any studio session. He writes pedal reviews for Guitarist and has contributed to Total Guitar, MusicRadar and Future Music among others.
