Can a Joyo MA-10B keep up with a single acoustic guitar?

    Title says it all. The amp is powered by AA batteries and is supposed to be 10 watt. At $35 if it is even remotely useful as an outdoor campfire amp it'd be great. Opinions please.

    I'd be shocked, but subbed to find out. :)
  3. Blowed if I know either but AA batteries give me the pip at the best of time. Bang a couple of rocks together instead?

    Hard nut to crack, that.....

    At the moment, decent bass with no electric, for much time, is expensive.

    Any good ones? All I know of are the Roland, the Pignose and now this. They all seem to have major issues, be it QC or volume. Do you know of an amp that is useful with a couple of acoustic instruments?
  6. You have to be willing to cart a battery and a speaker or you're whistling in the wind.

    Most compact effective is actual overkill v acoustic guitars indoors and you won't like the price. AER.

    For jamming with acoustic guitars I’ve found the Roland bass micro cube to be just fine. Long as the guitars are not plugged into an amp. YMMV.
    The Roland uses 6xAA batteries, nothing inherently wrong with that. I would be surprised though if a $35 amp would give you equivalent sound.

    I've always heard that the Roland is too quiet. I'm glad to hear otherwise

    If I were you. I’d get a Pignose 30. Do a search on these, great reviews for a battery powered amp. I did see your quote about issues with them, I have not seen this.

    My concern isn't that there are a lot of bad reviews, it's just that many of them are for the same reason. Which is battery failure. And many claims that you never actually get the full 30 watt volume. I will definitely consider your positive review though. Always nice to get a perspective from someone who has owned the product awhile.

    I was kinda tempted to get this one...
    Where did you see it for $35?

    Reviving this...
    Has anyone actually purchased this amp for $35? All the press releases read "$35", while all the retailers list it at $59, on the low end...
    Just curious...

  14. Honestly I can't say I'd be very confident of that one. An amp powered by AA batteries probably won't pump much juice very long, at 1.5 volts a piece and I'm not sure how many ampere hours, I'd just as soon get a used car battery and stone pawn shop car amp or maybe a circuit from whatever I could MacGyver. Either that or just rock an abg.

    I bought one to try for just that. I'll be flying to Brazil where my family plays acoustic and do sing alongs on the patio, so the small size and weight plus the battery power were all selling points for me. I also picked up an awesome, super padded camera bag insert with carry handle that fits the unit perfectly. Crazy that I can get this easily in my carry-on.

    The thing actually sounds decent in my living room which is pretty open, sounds great in a smaller room. It's a little quiet as can be expected, but I'm surprised by how loud it can get before farting out. We'll see how it does outside with an acoustic.

    I didn't notice any difference in output between the various power options; AA batteries, wall wart and using a 20Ah USB battery pack with a cheap 5V>9V converter. With the USB battery pack I can get hours of play time, probably over 8 hours. I also think the play time on AA is conservatively rated at 3 hours. I've done a bunch of little 20-30 minute sessions and it's still going on a pair of rechargeable Eneloops. Will do a proper endurance test when I'm down there but honestly the USB battery option will keep it going all day if needed.

    If the volume is enough for your needs I would say this paired with something like a Zoom b1four would be the perfect off-grid or travel rig.

    PS. I did try running both the Zoom and the amp off of the same USB battery pack (it has dual outputs) and it didn't like that, lots of hum/squealing.

    Hey folks, happy to report that yes, the Joyo MA-10B certainly can keep up with an acoustic outside. I set the amp in the corner and it projected wonderfully without farting out. Sounded great with a jumbo Takamine with moderately loud playing and fully inebriated singers. Good times had by all!

    This amp is perfect for being heard among acoustic instruments, sing-alongs, etc. I use either rechargeables (which last at least a few hours) or I run it off a power bank velcro'd to the back with a 5v to 9v converter (this is a fantastic option).

  18. Has anyone compared this to the Blackstar Fly3? I have the Blackstar with the extension and it farts out so easily.

    I should have mentioned this in my prior post. I got both, and returned the Blackstar (no extention cab). Neither of these products can stand next to a real amp even at low volumes. I was looking for something would bring a slab bass up to a volume with unamplified acoustic guitars (played reasonably). The Joyo did a much better job.
