Not for me -

Not a criticism of the product, it's actually a good amp but saving settings and having an app on my phone to jump between settings is not my style and quite frustrating. Do we really need 8 channel settings?

Seriously blown away by the sound and power of this amp. Anyone in the market for anything that Artist guitars sell do yourself a favor and buy it. I've ordered and received many items over the last month and even with the post office congestion due to the pandemic everything has been delivered in a timely manner.

A mighty fine little amp

Well to be fair, I had some doubts whether this 20 watt light weight amp with an 8 inch speaker would really have the muscle to rehearse with a full band, so I had an option to swap it for the 40 watt model if it didn't measure up. And I'm delighted to say that it surpassed any expectations I had. It sounds great, and my mate (the lead guitarist) actually asked me to turn down! He was playing through a much more powerful valve amp with a 2 x 12inch speaker enclosure, as well. I also love the idea that I can run the 20BT with a readily available 12 volt dc adaptor, which means that I can practice almost anywhere my car is! I was so impressed, I am planning to try it out at my next full gig.

So glad I decided to get this amp. I was borrowing a mate’s 10amp Vox and was about to get one for me, then I stumbled across this on Artist website ( that I visit often). Never even heard of a modelling amp before ( noob here). Great sound, lots of variety to get them”right “ sound and app is a great feature for us geeks. Gonna pair it with a TC59 soon, hopefully

Artist, you’ve done it again!!! Bought this little amp along with Artists TC59. Great sounding combo. Huge bonus for me is it sounds great with my electric acoustic guitar too. More features than you can poke a stick at. The built in tuner is spot on too. Can’t beat it for the price!

An excellent practice amp which punches well above its weight. A host of features, all of which are good. You can get just about any sound out of this unit. An excellent speaker for its size. I bought it for my son but he had a helluva job getting me off it! Beats anything else in this price range ($200-$400) on the market.
