Cordless practice amp/headphones.

Postby maxx england » Fri Nov 25, 2005 12:18 pm

If you can think of it, somebody sells it. I need info on some sort of cordless set up for a passive pickup guitar to transmit, in as direct a route as possible, to cordless headphones.

Your mission, should you choose to accept it, is to find me the information.

[updated:LAST EDITED ON Nov-25-05 AT 11:11 AM (EST)]I don't know of anything like that, but I guess you have most of what you need lying about around the house (in my case I just miss the wireless headphones)

guitar --> wireless --> preamp (or an OD pedal ) --> transmitter of headphones

if the wireless output is hot enough you may even be able to skip this step, I'd put a GT-3 or similar in this place, so I can give some reverb and speaker sim

Old timey radio headphones had high impedance electromagnets, on the order of 10K ohms. Bet they'd work directly from the pickups. I've got a set in the basement. I'm going to have to rig up an adapter and try it.

Haven't tried it yet. I'll holler when I get a round tuit. I think it'll work, but be aware that those headphones are the antithesis of hi-fi. They should be pretty close in impedance to a good hot humbucker or P-90, so the power transfer should be good. I think mine are 10K ohms. They worked well with crystal radios that simply rectified and filtered the AM radio energy coming from a 50' or so piece of suspended wire, and a guitar pickup will surely put out more voltage than that.

No, I've been busying myself with old Turkish Mauser rifles lately, cleaning enormous amounts of cosmoline off and out of them and most of my crafting's been making and installing leather slings.

I did discover the other day that surplus WWII era U.S. military communications headphones are not only high impedance, high sensitivity phones with a magnetodynamic armature design (not just the simple old coil and diaphragm of the amateur headphones I'm used to (that sounds like birth control devices, come to think of it), but they also have 1/4" mono jacks on them already! Experimenters may wish to hunt up a set.
