So this is the combo version of the VH100r. This thing seriously has like 3 effects loops. So I've got myself a MXR 10 band and a Decimator, but they don't sound right in the effects loop. The decimator barely seems to be doing anything at all. The instructions said that it should be able to cut all the ambient noise from the amp, but it doesn't for some reason. Like I can hear a difference between when it is on and when it isn't, but it doesn't completely get rid of the noise. I connect the send part of the effects loop for channel B into the input of the decimator (leaving the 10 band out for the moment, not enough leads ) and the output to the return of channel B. Is there some other way I should be doing this?
