Hi,
First, let me way that you have
way too much time on your hands.

lol
Second, I did a similar thing back in the late 70's using a Pignose amp, a funnel and some plastic tubing. It worked quite well. Actually I still have it though I haven't had the desire to
get funkified lately.
Seriously, it took a lot of ingenuity to put together your custom Talk Bucket. Have fun with it!
