Here's a short video i made today to demo some pedal sounds from the digitech RP80 and my valve junior. I also threw in a couple of different cupping styles to show the effect on a vocal mic.
The amp is unmodified except for a different 12ax7 in the preamp..not a very good one...not much difference when i put it in there. The wireless is the $20 singing machine from Radio shack, modified to take a standard xlr vocal mic..a samson r21. Speakers are Jensen. Sound levels near the mic reached over 105 db while recording this with the speakers about four feet away and aimed directly at the business end of the mic. The amp volume is at 9:30. The pedal is just off the heel minimum for volume. The pedal setting was further modified from one of the richard hunter website freebies. There is a tremendous amount of additional volume available for live use in a more open room ( approximately 117db measured at 10 feet). It's just too loud to use it in here.
Please excuse the bad hair and exhausted look..I am as exhausted as the video makes me look.

I am bumping this in case Phogi is interested in it, considering his feedback question and for Joe l who also had questions. It was buried pretty rapidly in this afternoon's flurry.
the cord goes into the body pack, like a wireless headset rig. that's what it is when you buy one..headset dynamic unidirectional mic. I snipped the cord and wired an xlr connector, trying to get my extra cable length as close to the mic boom length as possible since the wire is also the antenna. The other end is a 1/8 inch mini plug, so you could wire another mic for a ring mic or something. I use a holster with this mic since I also play conga, hand percussion, bongo, trumpet and sing. The battery life is very long and the range is something in excess of 50 feet, i don't have a place to go any farther than that without going outside...lol.

Cool. I was reading an article about wired power. There are some gadgets now that can transmit power using radio waves. I think they get something in the ballpark of 70% efficiency at a few feet. I wonder if and when you won't need a battery for these things.
Is it digital or analog? Did you do any tests with different length chord antenna lengths to see if you needed all the length? I guess that could very depending on how much interference there is. ---------- Nate Facebook
It's analog. I just matched the total length of my cable to the total length of the original, including the wire in the boom to the mic. I have wandered all over the church we practice in with no dropouts. I'd say the farthest i've been is 50 feet or so from the receiver, but there is no noise or fade or dropout at all. For 20 bucks, I'm astonished!
Singing machine also makes one with a mic and trasmitter integrated into the mic body for a completely cordless unit. I have to say i'm tempted to try one with the ball flattened like I did to my samson. The whole thing runs on two 9v batteries and they last and last and last. The receiver has a 1/4 plug right on it and plugs into your amp or pedal.
I will add that this experiment has all but talked me out of getting a lady luck speaker and using that money for something else. I will probably try the other singing machine mic, since I have another use for it if it isn't good for harp. The rest is going into cables for my PA.
