    What is the warranty?
    Ryan C on May 3, 2018
    BEST ANSWER: Hi Ryan. Not sure on the warranty. I think it would state the details on their website. I hope you have fun with that amp. i don't use it on gigs , however , it is a great practice amp and so easy on the back.
    Could this be used for Bass Guitar, Guitar, and music from my phone?
    A shopper on Aug 28, 2017
    BEST ANSWER: Yes, I've connected both a Bass and a Guitar to this amp. I can't speak for the phone, but with the right connector I don't see why it wouldn't
    Could you please put the correct users manual in the box with the amp or on this page?

    BEST ANSWER: working on it.
    Does 'direct out' turn off/defeat the speaker? Or can you use this as a direct box and stage monitor simultaneously???
    A shopper on Feb 18, 2018
    BEST ANSWER: "Line Out" does *not* mute the amp's speaker, so it seems like it could be used as a simultaneous direct box/stage monitor (tho it wouldn't be a very loud monitor). The "Headphones" line out *does* mute the speaker, and the volume of headphones is controlled by the volume knobs on the amp.

    Won't let you slappa da' bass!
    Really wanted to like this amp (I really did), as I ordered the guitar amp from Monoprice and like it very much. This amp however is fine as long as you're play soft and evenly. If you get a bit more aggressive with your playing (I was doing a slap line) then it just cuts out. By that I mean no sound comes out of it, like nothing, like dead! Once you return to playing softly the sound returns. That is a problem as I occasionally like to "slappa da bass". It almost sounds like there's an internal compressor that won't let you get to loud. Hopefully Monoprice stands by their gear and lets me return it.

    PROS: the price

    CONS: cuts out if you do any slap bass or play above a certain volume.

    Great and well priced.
    I got this off of amazon for twice the price which I promptly returned.

    However, in my time using it, I tried to play it out pretty loud and aggressively to see if it would have the problems some other users stated, and I did not. It is pretty good sound quality for the price. In fact, for $44 or less, you're not going to beat the sound. It sounds like my $110 amp easily.

    Great little practice amp for a low price.
    I really like this amp primarily because it was 20Watts and cheaper than Fender's 15W Rumble Amp. And I really like Monoprice. They do a lot of great stuff. The only downside is that since its so small and cheap it gets overdriven fairly easily. Especially since I have a BC Rich bass with Active pickups. Active pickups are very high output so the signal is pretty powerful coming out overdriving the amp. So if it's loud, the sound is distorted, not smooth and clean. I have to turn my bass master volume control down so the sound is smooth and clean.

    Also, I just have to say that Monoprice customer service is fantastic. They responded quickly and are eager to fix any issues. I was having some problems with the amp cutting out and they did their best to help me out and were up for replacing it until I figured out it was my bass problem. (crummy battery driving the active pups.) DOI!!!!

    PROS: Small. Cheap. Great Starter Amp. Portable. Sounds pretty good.

    CONS: Amp gets overdriven easily.

    Quality build.. For the price, can't be beat.. Very satisfied

    PROS: clean sound

    Sturdy construction

    2 inputs / outputs

    Good volume/ tone controls

    CONS: None really

    Great beginners practice amp.
    We bought this for our daughters for Christmas. One has been playing bass electric guitar, the other is going to start lessons in a month on a regular electric guitar. They can share this amp, and if they ever decide to play a duet, the dual input / dual volume will be great. Or if their instructor wants to play along with them they can plug in for practice or for a jam session.

    PROS: Inexpensive, dual inputs and volume controls, thick felt covering, weight is nice but not too light.

    CONS: The headphone jack is 1/4", I wish they had put in a 1/8" jack so we didn't have to purchase an adapter.

    nice unit
    i haven't tried to notify the neighbors of the amp's arrival, but for steady volume and practice, i'm pleased with this amp.

    Nice practice amp
    This is my second Monoprice amp and I really like it. The price is unbelievable for what you get. The felt cover over the whole things looks very neat and tight, not sloppy like some cheap amps I've seen. The sound output is more than sufficient for a practice amp. I'd bet this could be used in small venues and/or as an on stage monitor. There are no real bells and whistles, it just works well and doesn't cost much. What more could you ask for?

    Nice little bass amp
    I use this little amp for my electronic drum kit. It works great. Feels and looks well-made, and produces a nice, high quality sound. Would recommend.

    Good Practice Amp
    This thing sounds very clean. I was surprised by the soft sides and the gain which must be new. There is only one guitar input but they added gain and an iPod input. It is Stage Right brand not Monoprice brand.
