GAGA lets you play the tubes you want
"...i am amazed at the tone tweaking ability...with the Headroom and Volume knobs and ability to change tubes (i used a combination of 6v6's, 6ca7, and el34), i could get just the perfect amount of 'diffusion' i look for, so the guitar either stands out or blends in with the band or mix). the portability is another sweet point, added to the tone tweaking i just described, your amp is primo. ... on to another day of fun playing [GAGA], here's to you for coming up with the best of my forty amps!" -- Sporad Buzzic, New York, Jan 2012

"Tube amps traditionally have a 'sound'. But musicians are individuals. Why let any amp homogenize you? GAGA lets you mix tubes to make your own tone." -- Michael Milbert
The output tubes operate in full-power, class AB1, linear push-pull manner but without any traditional magnetic saturations, roll-offs, phase effects or hysteresis lags. GAGA delivers the purest possible tube performance.
