How to build an effects pedal for tremolo.

The Trill Tremolo pedal offers classic tremolo tones in an easy to build kit. The Speed knob provides a wide 
range from very slow to a rapid fire effect. The Depth knob varies the ratio between effected and dry signal. 
Using modern, low noise transistors makes operation of the Trill quiet with no signal drop when engaged as 
in some vintage style tremolo pedals.
