Beginner or pro, if you’re looking for a small, versatile combo that doesn’t break the bank then you may like to check out the new $139 G25 (opens in new tab) and $199 G50 (opens in new tab) guitar amps from Acoustic Amplification (opens in new tab)’s new Gamma series.

Rated at 25 watts and 50 watts, respectively, the all-analog Gamma G25 and G50 both feature twin channels for an expanded range of available tone (toggled via an optional footswitch or a button located on the front panel.)

While channel 1 (the “blue channel”) provides the kind of clean, responsive ‘blank canvas’ sound so often required for use with pedalboards, channel 2 features a selection of 4 different voices including Clean, Blues, Rock and Metal and is further augmented by a Drive control.

Though separate Volume controls have been included, both channels share the same EQ array comprising Bass, Mid and Treble knobs.

Whether practicing, writing, or recording these gig-worthy combos are both powerful and portable.

Weighing in at around 18 lbs, the Gamma G25 is some 7 lbs lighter than the G50 and measures a little under 3 inches less in width. This is due to its smaller 1x10-inch speaker configuration vis-à-vis the 1x12-inch layout of its beefier counterpart.

The G25 and G50’s custom-designed True Blue speakers are the Gamma amps' most obvious USP.

Boasting large magnets for maximum headroom and efficiency these drivers provide enhanced clarity, projection and response.

Aside from a regular input jack, the front panel of the new Gamma amps also houses a convenient line-level auxiliary input for hooking up external equipment. A headphone output has also been included.

Alternatively, you can always go cable free and take advantage of the G25 and G50’s simple Bluetooth funtion.
