Hello all! So i wanted to know what is the difference between a Palmer pdi-03 or 05? From what I can tell the only difference is the 4 1/4 inch out puts for effects. And running 2 amps at once. Is that the only difference? Also what the difference on each between the originals and the resissue as I have read the re issues are not nearly as good. And why were at it what did you use if you used one and how did you use it and do you still use it?
