Joyo MA-10A

I was hoping for better sound.
Maybe a faulty speaker, or loose screws inside.
Nicely finished with comprehensive controlls, plenty loud enough for a small placky box.
An hour trying different guitars and settings, but the mushy sound is not good for acoustic guitar.
Re: a week later the replacement MA 10 a arrived. I sat down again with the 3 same guitars and 2 different hook up guitar/amp wires, plugged in, switched on.
The sound of this replacement (a new ma 10 a) is far sweeter, a little more chimney than my first ma 10a & takes almost full volume & almost full gain before the dreaded 'mushy sound' syndrome begins.
Exactly what I was wanting, a nice clean sound at 3/4 gain & 3/4 volume.
A perfect stage monitor on a separate mic stand with a line in 6.3m jack, doubling as a rehearsal guitar amp.
Joyo is pretty good music gear, with a 3 year warranty, what more is needed.
