The vintage style Leslie Half Moon switch redone with new technology. Easy to mount, sturdy (inside is made of metal) and with that vintage style that is uncompared to other brands. With this you can control the digital Leslie in the new Hammond organs and stage keyboards (like sk models) or a real new Leslie connected to these keyboards, with a 3 mode switch (chorale, stop, tremolo). Obviously the outer shell is made of plastic so take care if you have to move the keyboard wich is connected to. It's the real thing. For those purists that accept no sobstitutes.
