The Skreddy Echo is designed to supply unity gain without any change in tone. Depending on the capacitance in the cables and switches in your signal chain, though, you may experience a slight brightening of your dry tone when your Echo is engaged. The Echo's mix control goes from 100% dry to 100% wet. At half way, you should get equal volumes of both dry and wet signals. The Skreddy Echo does tend to get a strong wet signal fairly early in the rotation of the mix control. Turn the mix down if you want a strong dry signal and a subtle wet signal. It does go all the way to zero; that's what the knob is for. If you need more wiggle room for subtle adjustments, you can always turn down the delay line's effect-loop volume trimpot, too.
