Keeley Electronics says its new rotary speaker guitar pedal is so good “it’s knocking industry titans off pedalboards” thanks to the fact it offers “the finest tone we’ve ever achieved”.
So, what justifies such hype and hyperbole? Well, the Rotary is (shock horror) modeled on vintage rotary speaker cabinets and the magic of Leslie speakers first found in organs – think Jon Lord-era Deep Purple – which use rotation for a suitably spinning sound.
