Whilst the Katana has a wide range of advanced features, It's clear and simple control layout makes it easy to dial in your tone by ear, just as you would on a standard tube amp. And with upgraded version 2 software, you have a whole new selection of added effects types and tone settings. The Katana is packed with loads of cool effects based on famous Boss pedals, as well as programmable presets and a few different amp styles, allowing you to really experiment with your sound without the need for a pedal board. The Boss Katana KTN-50 is a bedroom practice amp that you can take to a gig! Its power scaling function (from 50w to 25w to 0.5w) allows you to turn right down to 0.5W so that you can get a great sound at low volumes, but turn it back up to the full 50W and you've got enough power to compete with your heavy handed drummer!
