The fact that my mate had the "departmental" one in his drawer and I had just bought 3 for 93p each (inc postage) from China meant that I could just take it home and now it is mine.
Using it to change pitch on my G and D on my DB means that I can set up "clouds" of harmonics in the correct keys using my Neunaber reverb on infinite hold. The Neunaber holds the tails after it is turned off so I can just set up shimmery goodness. Of course, the real problem is that I now need a Strymon Big Sky
