Is there any danger in mixing up say a VooDoo PP Plus 2 power supply 3-prong cord with an amp 3-prong power cord? Are those all the same?
Do the ratings/specs match on each cord? If they do, great... if not, I wouldn't. Check both the Voodoo and the amp specs to see what they draw, amp wise... it may work one way, but things are going to get hot, the other...
The same with caveats. You do want a power cord that can stand what an amp can put out without burning up, but if it works for your amp, it'll work for the PP.
