feedback looper help

[bogey]

Hi all,

I built myself a feedback looper from the Beavis site and "hacked in a mute stomp and volume control".

Now the volume and mute work and so does the bypass but I'm not getting the desired feeding back effect when the feed back stomp is engaged and the feedback pot is just acting as a volume control.(I've tried it with and without lugs 2 and 3 linked).

So if anyone can take a look and see where I may have gone wrong I would really appreciate it.
