Alright, I have GNX3000 Multieffects pedal. My problem is when I start gigging, I fear I will break the plastic pedals and Matrix on stage. So, would it be in my best interest to switch to single pedals or is the GNX3000 (and other high-end effects pedals just as good)?

Also, if I go the single pedal route, which are the MUST-HAVE pedals (Please provide a small discription as to why, it'd help in purchasing) and what would be the best brand for each?

Finally, I have found several sources on making effects pedals and the schematics are so basic and easy I think I could make one pretty easily (at least the distortion and maybe a flanger or so), is this worth it and is it comparable?

Sorry for all the questions, I just want to have a good set-up for my pedals.
