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!

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.

Everything I expected I got. Excellent effects . Great sound for an acoustic slide guitar set up with pick up. Enough power to run with my one man band drum kit.
