Milbert Amplifiers GAGA 60-watt tube head
by Rich Maloof / Vintage Guitar, Jan 2014

PDF format   -or-   JPG format

Milbert Amplifiers has produced a genuinely revolutionary guitar amplifier in GAGA. Lightweight, exceptionally adaptable, and featuring an innovative transformerless design, GAGA may be unparalleled in matching versatility with supremely satisfying tube tone.

Under a hood of aircraft aluminum, GAGA has the capability to use any tubes, auto-match impedance to any speaker, adjust headroom, and provide phantom power for pedals. ...all players really need to know is that a transformerless amp allows pure, unfiltered tube response -- and that without a hunk of iron in the chassis, the head weighs just 12 pounds.

Any common power tubes can be used in any combination of two, three, or four tubes you like. Because the amp autobiases, you can even use mismatched tubes together to shape your tone. ... Without a transformer to drive, the distinctive qualities of different output tubes can be heard unimpeded. And because you can easily swap tubes after pulling off GAGA's top, the amp provides a singular opportunity to explore truly pure tube sounds. We exhausted only a handful of the hundreds of possible tube combinations...

Any speaker cab or cab pair can be connected to GAGA, regardless of load....

... well beyond the amp's capacity for emulation is an opportunity to discover entirely new timbres, and to nail a sound that otherwise exists only in a player's mind. ...touring musicians, session players, recording studios, and total tone hounds may find this amplifier undeniable.



Local Music Gear

"This amp is cool in so many ways! ...you build your tone and get to change it whenever and wherever you want. ...[Milbert offers] one amplifier that can perform as many different amplifiers -- and they did it correctly. ... you can get the sound of any amp you want with real tubes ... and [GAGA] weighs in at [12] lbs. Do I really need to say anything else?"


Performer Magazine, September 2014, pp. 46-47

GAGA, the Guitar Artists Guitar Amplifier ... uses advanced power conversion and other patented innovations ... to uniquely convey maximum tube tone and to attain what has previously been elusive: The verifiably purest-possible tube performance and a stunning "clarity of tone" that unleashes cleaner cleans, dirtier dirties, and a more natural, most-musical ecstasy...
