Since this is a new pedal and no one else has done a review, I thought I'd give it a go. A little background to get you started: I've tried many different chorus pedals over the years, in search of the perfect chorus for me. What really bugged me for a long time was the constant warble going up-and-down all the time. I loved the sound but hated the movement. Last year I stumbled across the Neunaber ChromaChorus, and Neunaber had a different approach to the traditional chorus sound - a slight static pitch shift. I bought it in a heartbeat and never looked back. Until Taylor whipped out his magic wand and.... Presto! Iron Ether Polytope! A quad-voice detuner pedal with an LFO, high-pass filter and separate volume controls. At first this pedal looks daunting with 6 knobs and 2 switches, but it really is quite intuitive. The clean knob controls the volume of the clean signal. The voice vol controls the volume of the effected signal. The detune knob controls how much the signal is detuned. The range switch affects how much the signal can be detuned, thus widening the range of the detune knob. The Mod switch turns the LFO on/off and when the LFO is on, the detune knob controls the depth of the pitch sweep. The voices knob controls how many 'voices' are added to the detuned signal. Initially it's one voice up, then it gradually adds one voice down, the one more up and lastly another one down. The filter knob is basically a high-pass filter, which controls how much of the low-end is effected. The Polytope is a very interesting animal, capable of extremely weird sounds, massive detuning and a fantastic shimmering chorus type sound. I've had this pedal about a week now and I'm kinda getting to terms with the fact that I'll never use it to it's full potential. The massive detuning and the LFO is, for me, just too far out to be usable in a musical context. I know a lot of you guys out there are far more radical in your approach to music than I am, and for those of you, listen very carefully to Excanes demo, as it shows the full potential of the Polytope. Aside from the sonic annihilation that this pedal is capable of, it also can make a bass line come to life. By detuning it ever so gently, with a single voice added and the filter set high, a quiet solo line in the upper frets sounds like a slice of heaven . Adding more voices intensifies the 'chorus' sound, making it deeper and more lush, but still it maintains a very strong fundamental. The range of the detuning knob is very wide even in it's narrow mode, turn the knob after 1 o'clock and it detunes far beyond reason IMO. But in between 9 and 1 o'clock there is pure gold to be found. I love the fact that this pedal has separate volume controls, thus making it far more useful even on more hardcore settings. All in all, the Polytope fulfills classic modulation needs with great flexibility, and still has truck loads of sounds left to spare. The sound quality of this thing is as all Iron Ether, amazing. I don't know how he does it, but nothing sounds just like this, the ChromaChorus gets close, but Taylor made this just a liiiitle bit better. I e-mailed him last week to give my feedback and I'll tell you what I told him: An Iron Ether pedal has never disappointed me in any way and this is no exception. As long as he keeps making pedals like this, I'll keep buying them.
