The Mooer Trelicopter is a tiny but powerful optical tremolo! There's even a bias control that lets you alter the shape of the tremolo to create a non-symmetrical wave just like a vintage valve amp! Control over speed and depth too allow you to tailor your sound even further, whether you want sublime or ridiculous.
We'll let you decide for yourselves what you think the inspiration behind this thing is but suffice to say it sounds great! Just check the Youtube demos!
