So these are the easiest effect pedals to master but there are many out there who never touch either of these.
At 0.08 i bring in the delay effect pedal. Essential what a delay does is it takes the incoming signal and repeats it a few times.
The first knob to look at will be the Level knob. this controls how loud the delayed sound will be compared to the original signal. Below 50% means it will be quiter than the original signal. above 50% means it will be louder. 100% completely mutes the orignal signal and only plays the delayed signal (useful for ping pong delay which i will do later).
Feedback control how many times the signal will be repeated, 0% means the signal will be repeated only once (this can be used for a HAAS effect - which i may talk about in the future).
The 2 delay time knobs control the speed at which the original sound is repeated. Eg - 1/16 at 3 steps. Meaning every 3 steps it will repeat the signal at a rate of 1/16ths.
At 0.20 i mute the delay and demonstrate the reverb. The reverb works in much the same way albeit a bit more complex. Like the delay a reverb repeats the original signal over and over, but instead of 1/16ths it repeats it a couple of hundred times in very quick succession, creating this kinda "echo-y hall" effect.
The feedback knob controls how fast the repetitions will be, changing the overall tone of the reverb.
Room size controls how long the reverb "tail" lasts for. And predelay controls how long after the incoming signal that the reverb begins to repeat the sounds, also changing the tone and character of the sound.
Damping, like the name suggests, dampens the sound. So instead of it sounding like its echoing in a hall it could sound like an almost underwater style echo.
Level controls how much of the sound is "drowned" in the reverb. Meaning 2% is very subtle and 100% completely drowns it.
