The "Slap" knob is the amount of delay time. As you turn the knob up, you will get longer delay times. Keep in mind, this pedal is designed for shorter vintage slap-back delay times.
The "Mix" knob is the effect level. Full counter clockwise is all dry and full clockwise is full wet/effect. The "Repeat" knob controls how many echoes or repeats you get. The minimum is one and maximum is around 4.5 repeats.
"Repeat" knob lets you fine tune how many delays you will get. Lastly is the "EQ" knob. This control only affects the repeat delay signal so that you can perfectly adjust the brightness or darkness of your echo. When fully counter clockwise the repeats are at their darkest much like an old BBD analog delay. When fully clockwise the repeats are the brightest they will be with more grit, this is much like a classic tape delay machine.
The longest echo/delay time on the Milkman is about 240ms. The footswitching is our typical 2 in 1 arrangement where either effect can be used separately or together.The foot switch on the left, the switch will turn the delay on/off and the footswitch on the right will turn the boost on/off. The Milkman uses standard 9v DC Negative power only. This item is in the category "Musical Instruments & Gear\Guitars & Basses\Parts & Accessories\Effects Pedals\Delay, Echo & Reverb".
