Quite surprised with the sound. Although not so much with the perceived power. Anyway, satisfied with the purchase. Good price-quality ratio. Just one drawback: the equalization controls are not very useful. They could be improved, I think.
Very good.
Pretty good little 30watt amp. My krockit monitors are better than this but the usb power is kind of handy.
It's small in size so it's easy to move around. The advantage of being able to connect with a Type-C cable and battery for cordless use is also nice... Just don't expect too much output.
It is exactly identical to the description, very good finishes, and considering that it has a 4" cone, you can't ask for more. It's suitable for practicing at home and even for a small gathering of friends playing at a low volume.
Unfortunately a lot smaller than i thought and shipped with the incorrect power plug, i can not complain about the service but just wrong product for me
Good little practice amp with nice eq features and compression. I haven't tried the battery life yet. The sound us pretty good, better than the ba10. These little practice amps were what got me good, because i could play anywhere; at the beach: during my lunch break, waiting in the car park for a mate. Definitely recommended this for becoming a better player.
Good, mature sound from this small combo amplifier. The only issue is that the guitars get slightly electrically stinging, and all my basses are affected - not sure what the reason is.
Great little practice rig and full sounding travel amp. The tone is incredible for its size with the passive radiator rounding out the bottom end nicely. Does for bass practice amps what the mesa walkabout scout did for combo amps back in the day. A comparison that keeps coming with a mid range parametric eq and similarity in design. Pj bass, short scale and acoustic bass with piezo o/up tones are all easily dialled in from clean to a light overdrive with humbuckers or active p/ups. Has replaced my excellent yamaha thr-10c as my battery powered rig.for bass. Put simply the joyo ba-30 is louder and reproduces a full tone that sits perfectly with one or two acoustics and the yamaha thr-10c with a telecaster or strat. Can it “compete” with drums? If it’s a competition then absolutely not. If the drummer can play along to an acoustic rehearsal then the joyo-ba30 will make it the best acoustic jam you’ve ever had. Bluetooth practice on the couch to great jams anywhere anytime i love it.
Very satisfied. The sound quality is great for the size, and you can practice at low volume. I also appreciate that they sent a KR plug instead of an EU plug.
