I'm not sure if you my email, so here goes.

My advice is that you go to a local music store that allows you to sample the effects. That way you can get a feel for the tone you want to achieve and which stomp boxes you will need to achieve it.
Buying online is extremely convenient, but you don't always know what you are getting.
My personal opinion is to stay away from Rogue brand pedals. They are (I think) sub-standard and have lousy tone quality. All of my boxes are Boss brand and I have continued success with them. Excellent quality!
