Question: do you have to use headphones? can i use it as a portable mini amp ?
Document: Either get a standard eighth inch to quarter inch adapter for headphones, or even better get a portable mini amp that emits sound that doesn't require headphones.
This thing is all right for what it does, but either way I wouldn't buy it again. If you are REALLY dead set on using headphones, then just buy an eighth inch to quarter inch cord adapter. It's cheaper and not as bulky. Personally, I hate headphones when playing - I like to hear myself rock out. They make a lot of great, inexpensive products similar in size to this one that actually emit sound and act like a mini, portable amp.
Totally new to guitar, and just needed something to use for practicing in my apartment without having to pull out the amp and headphones and plug everything in and la di da. In other words, I needed something quick and easy. Plus this is the mini equivalent of the amp Brian May of Queen uses. (It is my mission to play Tie Your Mother Down at SOME point in the near future. )Anyway, it works, it sounds good, it's easy to set up, it's lightweight.
Bought this to use with my Traveler UltraLight guitar. Does what it's supposed to--renders electric guitar sounds for headphones without taking up much space in my suitcase. Batteries have lasted several weeks. Limited in the variety of sounds produced, but certainly enough for practice and laying down new sounds in conjunction with a portable recording device (I use a ZOOM H1). Seems rugged enough. Made in Japan--haven't seen any electronics from there in awhile.
I really like this little headphone amp. It has great sound, a few different effects and doesn't cost an arm and a leg. When I was looking around I was trying to find a portable with a little built in speaker. This does NOT have a speaker. Headphone use. It does have an aux on it which is fairly neat. The batteries it came with actually worked fine for me.
For me, that's around 4-5 Volume= whatever's comfortable.There's also an aux port. Now some people use this to pump an mp3 player though it. And that's perfect - but I have a secret - You can also use this to pump this puppy through a speaker. Connect a 1/8 stereo audio cable into the headphone port on this thing, and connect the other end to either:1 Your PC's Mic input2. An external speaker system's input socket.Viola- instant mini amp.
I also like the fact that it uses easy to get AAA batteries instead of expensive 9V batteries that almost all of the other portable amps use, nice. And the battery life is also good, with around 15 or so hours between changes if using Duracell.All told, this is a great little practice amp, with great sound, good battery life, and ease of use all bundled into a neat, compact package. Highly recommended!
I don't have to use my amp to play my electric guitars. I have been a big user of headphones for years. to be able play my guitars without using some bulky, clunky unit to play with.
I've read all kinds of reviews here, and made my purchase. This product is barely OK and it's over rated.To start with, I don't think it compares with the real amp. Bends cannot be heard clearly, too little clean headroom and sounds nothing like the real thing except the tone. I pretty much dislike the sound because when I use headphones I would expect more details. However, this thing doesn't do details.
very easy to use and take with you on the road for some jamming. I even bought the optional 1x8 portable cabinent for some jamming with friends where i want others to hear. great little combo and easier to transport than even my Orange micro.
Answer: Well, it doesn't have its own speaker so it can't work by itself. But if you have a portable computer speaker that is self-powered, you should be able to connect that to the amPlug and hear what you're playing. But since there's no speaker, you either need a speaker or a pair of headphones for it to work :)
