Joyo AC40

By: on 26 December 2021
I have only had the amp for about a week and haven't used it outdoors as yet, but probably enough to say that I pulled it out of the box and two hours later was still playing. It's great. Love the three effects being mixable and I'm having heaps of fun playing to the delay. Great sound when you've got the timing together. The mic input having independant volume and reverb is excellent. The hiss that some people have mentioned is just not an issue. I can't see why it would bother anyone who wasn't looking to nit-pick. Super prompt delivery. And all so affordable. I bought it because I had busked at a market the week before with a borrowed battery-powered amp that was very poor in comparison. Thankyou very much. I love it.

I bought one and the noisy hiss is very noticeable. People comment on it. I wouldn't have bought it if I had known it would be so loud. It's not a fault just bad design. Avoid

I am getting a great sound from this amp with my Cole Clark Angel acoustic guitar. The fx are all I need and I am looking forward to experimenting further to get the most from this amazing little amp.

I purchased this amp to use with a double bass in situations where power is not available. What I have found with other battery amps of a similar size (not to mention price!) is the output level just doesn't cut it. With addition of a pedal graphic eq, the sound is very good and cuts through with a full band while still retaining an authentic acoustic bass sound. Played for 5-6 hours before I charged the battery again just in case. And as a bonus it sounds great with my hollow body 6-string jazzbox. Great purchase!

Acoustic Guitar Amplifier

I've now bought a few instruments through Artist and have been well pleased each time. A couple of acoustic guitars - nylon and steel string. Both perfectly fit for purpose. Excellent value for money. The latest experience is no exception. I had a small modelling amp which I was using with the guitars but was never delighted by the sound - too harsh and brittle. Plus I liked the idea of something that didn't have to be plugged into the mains. The Joyo AC40 is that amp. Very simple to use. And a nice, warm sound when used with the two Artist guitars. Again, excellent value for money.
