Hello, I just got my new Spider iv 30 watt and wanted to know if it is safe to use a Wah pedal- Digitech RP300- and a BOSS mega metal pedal with it? i know the onboard effects are wonderful. bUT limited I do not want to damage any components. I have some great presets that I have designed on my Digitech RP 300. If I do use it I am sure I would want to use it through a clean channel. I am not willing to take a chance until I have spoken to "The CommunitY" ON THIS MATTER. I am also curious if a wieless system will funcrtion without any noise or causing any component problems.....Please Help...THank You so very much....Dennison
