    Rechargeable Mini Headphone Amplifier for Guitar - Acoustic

    As a musician you know you need to practice regularly to hone your skills and learn new songs. However, you can't always break out the amps and crank up the volume. For those times when quiet is required, you can both practice and hear the amplified output from your instrument using this Rechargeable Mini Headphone Amplifier for Guitar from Monoprice!

    This amplifier is designed to provide amplification to the output of instrument level devices, such as electric guitars and bass guitars. It features a 1/4" TS plug, which plugs directly into your instrument's output. It is powered by an internal, rechargeable battery and has a 3.5mm TRS output for listening with headphones.

    An additional 3.5mm TRS auxiliary input is provided for connecting another audio source, such as an mp3 player. The audio from the Aux jack is mixed with the audio from the guitar so you can play along to an existing recording.

    This amplifier produces a clean "Acoustic" sound reminiscent of an acoustic guitar performance. The amplifier includes analog Blend, Tone, and Volume controls.

    Pretty good

    Pros: Works well.
    Small problem easily fixed.

    Cons: Falls out of guitar easily.

    Works fine. Like others, I had trouble with it falling out of my guitar easily. I put a tiny piece of masking tape at the top of the plug (where it meets the plastic), and this gave it enough extra snugness to remedy this problem. Rock on.

    Great sounding practice amp

    Pros: Sound - Good volume, clean tone. Aux signal volume is not adjustable but you adjust that at the source.
    Features - Mixes your instrument signal with an external music source, a must-have for me.
    Build Quality - Solid build, all controls work and has been reliable for the four or five months I've used it.
    Compact - Lightweight, thin and doesn't look like the cheaper units out there.
    Rechargeable - I don't go through AA's anymore. Yes!
    Price - Can't beat it. For around $10, just buy it!

    Cons: Few issues here except for the too short 1/4 inch plug being the major drawback. Seems like this is a design issue which hopefully someone will address in future versions. Otherwise an excellent solution to practicing silently to an external source.
    USB connection is a mini USB, not micro which is more popular today, but that's not really an issue.
    Acoustic effect makes almost no difference. I honestly can't tell whether it's on or off. No matter to me anyway.
    Excessive hiss when turned up near max volume, but is very clean at usable volume levels. This is to be expected with a unit at this price and hasn't impacted my use of this item at all.
    Charge could last a little longer, but I don't practice all day anyway. If that turns into a real problem, I'll just buy another one and trade off.

    Nice little unit that I've been using consistently since I bought it a few months ago. I plug it into my bass and use it to learn songs and rehearse prior to band rehearsals and gigs. I like not running through batteries and the charge seems to last long enough (approx 2 hrs). When it dies, that tells me that I need a break anyway, so no problems there. To reduce cables, I've attached one of those thin square rechargeable bluetooth receivers to the back of it that pairs with my music source, so now I can walk around and practice my jumps, kicks and splits like a real rock star (JK). On the down side, I will echo others in saying that the 1/4" plug is a tad too short as I had problems with it regularly dropping out of my bass during normal use. That bugged me so much that I decided to open it up and do a little surgery (and I know, void the warranty) to move the plug out a little then glue it all back together. I was successful in doing that and now it stays in my bass. For the price it was worth taking the risk IMO. That issue aside, it sounds great and does a great job. The acoustic effect is not really prevalent, so don't buy it for this feature alone. I wanted a clean sound which is what this delivers. Overall I recommend it and will buy another when this wears out. Definitely worth buying one yourself, so what are you waiting for? Buy it!

    Works OK, some shortcomings

    • Doug Claar,

    Pros: Rechargeable. Inexpensive. Has more than enough volume (for me anyway). Sounds good.

    Cons: 1/4 jack is about .1" short, so it may not stay in. It stays in my uke, but not an extension cable.
    Headphone jack can be a bit fussy: It worked fine with two headsets, but the other one didn't stay in contact.
    Absolutely no documentation.

    I have a traveler uke with a piezo pickup. Because of the impedance of the pickup, a lot of things don't work too well, but this woks great with standard headphones or computer speakers. I don't really know what the FX position is for, or how well it worksthere's absolutely no documentationbut it sounds good in the regular position. (and anyway, heavily distorted ukes aren't really a thing, or at least not my thing).

    Pros: Sounds great for acoustic guitar and bass. Rechargeable with a standard usb cable. Haven't had any issues as of yet. Works great!

    Cons: Construction is fairly cheap feeling but what would you expect for the price.

    Great little practice headphone amp for the money! I personally use it mostly for bass and it works/sounds great!
