The Trill Tremolo

The Trill's speed knob provides a wide range from a very slow to 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. The Trill uses true bypass foot switching so it is out of the signal path when not engaged.

The 1ML depth control doesn't seem to reduce the intensity of the effect very much, is there a fix for this?

Yes. We have provided a schematic showing how to connect a 1MA pot acting as a variable voltage divider (instead of a 1ML pot acting as a variable resistor) for a more dramatic "intensity" control effect.
