I thought that was the solution too, until I tried it today. It doesn't 
help. When you overdub a sustained sound over the startpoint boundary of 
the loop the repeater gets a pop in the loop at that point. This is after 
you have recorded the loop and you are just overdubbing sustained sounds 
across the loop startpoint when this pop happens. I guess this is the 
"bump 
issue" people are talking about. Kind of a strange problem really, I guess 
it might have something to do with the padding they add before and after 
the loop in memory.

Like you, I first thought Simeon below and others meant a different 
problem, where you get a little noise in the initial recording at the 
startpoint caused by the waveform at the end of the loop not matching 
exactly to the waveform at the beginning. Both the repeater and the edp 
deal with this by using crossfade techniques, which improve it a lot but 
are not always perfect. (other loopers don't do anything, so you get 
little 
pops.)  that can usually be further improved by the technique of going 
directly into overdub from record as is easy to do on the edp. Since 
repeater doesn't have the ability to do that direct into overdub function, 
I figured that was what people were having trouble with. Recording a blank 
loop first and then starting your loop with overdub would be a workaround 
for that (although an awkward one), but now I see that doesn't work either.
