Just received my noise gate, and I've noticed that when it's on, theres a very slight delay between picking a note and it reaching the amp, or so it seems anyway. Why is that?
Its called "latency" - its caused when a signal has to be converted from analog to digital or vice versa.

What pedal did you buy?
Probably because your gate is still cutting off when you pick a note.

Do you have anything in your chain that is digital?

Erm, I have a cheapo delay, and a digitech whammy also in my rig?
Try just running the pedal alone with out the other pedals on your board and see if you still have the problem.
