Hey I just got my Decimator G string and was advised i could use this directly in front,

i.e. guitar -> decimator -> amp.

I havent got enough cables for the fx loop at the moment, but realistically all i wanted it for was to get rid of heavy feedback.

How do i connect the thing?

If i follow the instructions:

Guitar -> guitar in -> Decimator -> dec out -> amp input, then it's significantly filters out my signal and there is no bypass.

How would I set this up?
