I’ve had this one sitting around far too long! Here’s a look at the very affordable Joyo Mjolnir all tube mini guitar head. It’s 15 watts & we measured the output at 120db!! That’s REALLY freakin’ loud. Loud enough to keep up with a drummer. We measured 120 db coming out of this 15 watt amp. That means it’s really freakin’ loud. How does it sound? Check it out for yourself! I love the concept of the “lunchbox amp” small, lightweight and portable. Perfect for the gigiing musician! But it has to be able to deliver the goods in terms of tone…. Watch the video and decide for yourself on the sound!
