Here at Noisegate we went deep to compare 3 different battery-powered, micro, mini, portable, mobile, coffee table or whatever you’d like to call those small handy little battery powered guitar amps. These amps are great for those who need a portable guitar sound on the go. We brought in a crack team of audio and acoustic engineers and spared no expense in setting up our studio, so we could best compare the tone of these 3 popular battery powered amps. In our video we check out the Marshall MS-2, Blackstar Fly 3 and the IK Multimedia iRig Micro Amp. Which one had the best tone – watch to see our verdict!
Tech details:
Andy plugs straight into the amp, with sound recorded via an AKG C414 condenser through a Universal Audio Apollo X8 audio interface. Effectively you’re hearing the tone straight out of these amps. What do you reckon, let us know.
