I'm pretty sure most small combos come with HP jacks. Might have to get a 1/4 adapter unless yours already has it.
I got a Korg Pandora Mini to practice around the house so I don't disturb others. Only problem is that the headphone output is pretty whimpy.
Have you tried amPlug from Vox? VOX | amPlug | Headphone portable guitar amp AUX in jack lets you play along with your cd's / mp3s player.
+1 on the Vox bass amplug. It is plenty loud, has aux input for cd player or iPod, and you can plug it into the output side of an effects pedal. With 2 kids in the house I use it way more than my combo amp.
Our dorm apparently doesn't follow that rule too strictly. Smaller amp and headphones works well for me though, as I did follow the rules. Not exactly the most musician friendly environment all the time.
do what i do. cheap four or two channel mixer, headphones. you're not electronically amplified anymore, since there's no speaker involved. works very well.
I use my Fender Rumble 15 practice amp in my apartment (kind of the same scenario). It has a headphone jack and does the trick to allow me to play without totally pissing off the people around me. Just get some quality sounding headphones though.
I used a $50 behringer mixer and a good set of phones. It worked great and you could mix in whatever you wanted.
I've definitely been through this. For your dorm room, a headphone amp will be the way to go. As for other prospects, see if your school has any kind of rehearsal rooms. If there's any kind of a music / arts program, there are likely to be some rehearsal rooms that you might be able to use. My school had some of these. They might be kind of small, and getting an amp there can be a little tricky. But it might be one of the few locations on campus where you can play through your amp.
I was just at GC Danvers asking about this exact product when someone called and asked about it too...I figured it must be someone from here...what are the odds The guy tried to sell me the guitar one...I'll wait and get the one for bass online. I think it will be good for my kid's camps/traveling this summer. Thanks for the tip Handaer!!
I live in the dorms too and I use my bass, into my EQ pedal, into an M-Audio Fast Track with studio headphones for my practice sessions. I've been amazed with how good it sounds, and using the Fast Track I can balance the level of the bass with any song/backing track I'm playing over.
I'm gunna third on the Korg Pandora, you can even use the USB for laptop recording stuff too and it sounds great. It also has a crap load of drum loops and effects.
I use a small 2/4 channel mixer. That way I can practice with a 2nd musician and we can put an mp3 player in the mix as well and just split the headphone signal. I use this: Mackie - 402-VLZ3 But, I do that because I have sleeping kids in the house, not because I live in a dorm.
