Strymon Lex -Rotary Speaker Simulator $299

"Lex provides you with a complete, accurately reproduced rotary system: the low-frequency bass rotor, the rotating treble horn, the tube-driven amplifier, finely tuned microphone placement, and all the complex sonic interactions between these elements. Utilizing a ridiculously powerful SHARC DSP, every drop of processing power is harnessed to authentically represent these details.

You get eight parameters to tweak, allowing extensive control over the tonality and mechanics of the rotating speaker system. You can manipulate each element, from rotor speed, horn level, acceleration time, microphone distance, tube drive and saturation, and volume level. Go from a maelstrom of dramatic, up-close, sweeping and swirling sounds, all the way to mellow, tranquil and calming undulations. All of this without a giant cabinet, microphone setup, and costly motor maintenance."
