Just never have used one.. have never even TRIED one.. I'm not a big effects kind of guy.. right now all I run is a distortion pedal and echo.. I have a noise gate that I use on some songs, and an inline tuner.. I did just buy a harmonizer pedal, that creates a second guitar in harmony with you, but haven't learned how to use it properly yet.. its freakin' complicated!
I like to let the Marshall do the talking, so I put as little between me and it as possible..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
