Is there any way I can output from my Session 400 into headphones so I don't annoy the neighbours if I want to play late at night ?
Failing that - do I need to go through the Session at all ? I have a Behringer PB100 premap booster (which I bought for something else and never use anymore) if that helps ... |

Two solutions I use. I've got a "Rolls Personal Monitor" amp. Actually its a headphone amp. I plug that ito the line out on the back of my NV-1000.
I also bought a Zoom G2 unit that I use to practice with and take to jam sessions. That way you don't need an amp at all. It's got reverb delay and all that built in. It also runs on batteries so its extremely portable. I find the sound to be acceptable for headphone use. You can find them on the web.
I use AKG 240 phones. They cost mor than others bit IMO they're the best. You can wear them a long time without getting cauliflauer ear. |

Thanks Tom.
I don't think the Session 400 has a line out (can't see one on mine anyway). I'll look up those devices you mention. |

There is a booster output that is taken off the final output stages. Just unplug the speaker and use that to drive the headphone amp. The output is less than 10,000 ohms and close to 1 volt RMS.
A transistor amp will tolerate a "no load" situation. It cannot tolerate a direct short! Output transistors can self destruct in as little as 50 milli-seconds when they are shorted out.
Just a not, a tube amp is just the opposite, it can not tolerate a no speaker load, that can destroy the output transformer. Fender used a shorting jack on the speaker output to cause a direct speaker short when the speakers were unplugged. That saves the transformer. |

| Ken, I have often plugged headphones into a stereo to mono adaptor, and plugged that straight into the speaker jack of an amp. The phone spec. impedance seems to match a 4 to 16 ohm speaker jack. I have the volume off on the amp when I do this, then I bring up the volume to a listenable level in the phones. It seems to work and has never damaged an amp or phones. Is there a reason not to do this? |

| I do it in the shop all the time while testing for low level noise problems. Just keep in mind a nice loud bass note can burn out the small speakers in the headphones very easily. |

Just took a look on Ebay, and there are loads of cheap "headphone amps" designed for you to plug an electric guitar in one socket and headphones in the other (e.g. Danelectro EStudio).
Ken - just so I get this right & don't end up blowing my head off - am I right that you are saying its better to take a lead from the booster socket of the Session as input to the headphone amp rather than plug the steel directly into the headphone amp ? |

| A 200 watt amp running headphones can be bad for both hearing and the little speakers (probably rated around a watt or less) in the headphones. A headphone amp will be much better suited to protect both yours ears and the headphones. |
