I like that easy answer to the "line out jack" subject. How many times have we been on a gig and wished we could plug in a set of headphones to hear how our guitar sounds regardless of what the tuner says? ...without the whole room hearing what we're doing? I have a Rockman that will do this but it has to run thru my effects and it needs its power supply plugged in to work. Too much to hook up and fiddle with. I know some amps have this built in but how could one do this with other amps? Is there some magic box that will do it? --JR |

Peavey makes a small headphone amplifier that works nicely for this. It accepts input from a line out jack on your amp and has its own volume control. If you use a stereo preamp of effects unit, it will accept stereo inputs as well. I think the model number is the HD-1.------------------

I use a zoom 505 guitar stompbox that i carry in my pacseat for this. I have a TTfex but hardly ever use it now, i'm back to the basic "less is more" guitar/amp thing. you can pick up a used zoom505 on ebay for fifty bucks or less, sounds great with headphones and not to bad for other effects if thats what you like.

John,
This is rarely implemented on guitar amps because of reliability. A standard stereo headphone jack has a built in switch so that when you plug the headphones in - it switches off the speakers. The contact ratings of the best Switchcraft switching jacks are usually less that what you need for speaker current in a high power amp. They are Ok for most stereo systems.Also that large amount of available current needs to have limiting resistors in series with it. Not because it will blow your ears out, but for inadvertent shorts. When you insert a stereo plug you short across the contacts. The only way I would recommend this would be to add a non-switching jack with a 100 ohm resistor from each channel (L and R) and tie them together to the normal speaker jack output. You will need to unplug the speaker to silence it (if you amp has a speaker jack and plug). ------------------
