    Does this need power/battery?
    Lau N on Feb 3, 2017
    BEST ANSWER: Yes, it uses two AAA batteries. They last a pretty long time. There is not a way to power it from another source.
    Do you have a phone number that you can email me so I can talk with someone about ordering a bulk supply of headphone amps?
    thank you,

    I want to use this with an acoustic-electric violin that has a passive piezo pick up. Does this support high impedance output from the violin pickup such as 1 Ohm?
    A shopper on Jan 24, 2018
    BEST ANSWER: Yes, you may have to adjust the volumes on the instrument and the amp if there are any noise issues.

    Works for bass, too
    I bought this at about a third the price of some of the equivalent devices from "name" amp manufacturers. It delivers! It would be perfect for me if it included some base metronome functions and connected less directly to my instrument.

    PROS: I am happy with the battery life and volume of this little practice tool. I am able to hear the difference between the pickup configurations and tone settings on my bass, and that is all I hoped for!

    CONS: Put a strap clip on this and a couple feet of cable and you could better keep this little amp out of harm's way. Sound adjustments have to be done blind if your guitar's jack socket is on the bottom instead of the face of the instrument. The aux in jack does not seem to be stereoI cannot therefore hear aux input through both earphone jacks (nor is it loud enough to be practical).

    Good value for the price
    I bought this to noodle with my bass while watching TV. Pots are reasonably clean. This is not a Vox but is is also not $40.

    PROS: Inexpensive
    sounds good with both bass and guitar

    CONS: Plastic

    Cheap way to play guitar through headphones, nice product!
    This gadget is a must-have if you have a teenager that likes to fill your house with loud guitar music. Confine all that noise to a pair of headphones for under $25? Yes please! It fits right into the amp port on a guitar and doesn't interfere with the strumming area at all. There are three controls (gain, tone, and volume) and an on/off switch. I haven't played with the aux in port, but I assume it works as advertised.

    PROS: Cheap, clever way to play guitar through headphones without having to use a large amp

    CONS: None yet, product is awesome!

    Just fine
    Decent clean sound. Easy to use.

    Has a "drive" knob that wasn't advertised so you can get some overdrive distortion if you want it. I don't and don't use it. It was hard to find an amp like this that just delivered a clean sound so I'm happy to find it.

    PROS: Works fine, as advertised

    CONS: None

    Great little device now I can play anywhere when I'm not at home.

    Great Practice Tool
    See "Pros".

    PROS: This device is my sole practice tool. The sound quality is perfect, it doesn't disturb anybody, and with the aux input, I can plug it right into my smartphone if I need to play along to a song or click track. Any pro musician should have this. It replaced my Pandora and it cost one tenth of the price.

    CONS: None.

    Headphone (clean) amp- delivers as advertised, works for bass too!
    Used this gem for about a month. Primary use is for bass guitars.
    No problem with pots / controls, or hiss. I've used on several basses as well as a Strat.
    'Clean' sound is true. A prior reviewer suggested a short cable and a clip to keep it out of harm's way a good idea! or be VERY careful, after all,it's plastic and inexpensive. That being said, I've shared it with my bandmates. They liked it as well. Happiness! Now I can practice at whatever time.

    PROS: Nice unit, works well on basses as too! mp3 audio plugin a nice plus.
    Under 15 bucks- great

    CONS: All things made of plastic will eventually break. Without abuse this should last a long time.
    Great little unit
    Great sound, and well built. Does exactly what I wanted it to do.

    Excellent With Slight Modification

    PROS: "Clean" sound version is the best of the three. Works very well.

    CONS: The 1/4" jack is not stable stuck in the guitar body and can easily be broken off BUT by adding a female to male 1/4" ext cord you can solve that issue. Once you've done that it's PERFECT!
