Our best and easiest EA Tremolo circuit new for 2021.
Description
One of the easiest and best sounding Tremolo circuits available. The excellent buffer associated with this circuit also enhances your guitar tone while using it. The LED will blink in time with the SPEED potentiometer. This can easily be done in one of two ways. Use a Bi–color LED so it is always blinking and you know the SPEED of the Tremolo before activating it or use a Standard LED and it will only blink when the circuit is activated.
