Acoustic Amplification

While the brand name is Acoustic, this is actually designed for electric guitars, with a button that lets you switch between two channels – Lead and Rhythm.

Acoustic is a lesser known brand that build good quality amps, one of which is the Lead Guitar Series G20, a 20W 1 x 10″ solid state combo amp rated highly for its tone and simplicity.

The Lead channel comes with a gain knob for adding overdrive, while both channels have dedicated volume controls.

Tone shaping is done through its 3-band EQ, with the addition of a “mid-shift” button that transforms the way the mids behave. This mid-shift button expands the sonic flavors that you can get out of this seemingly simple amp.

Other features include aux input and headphones out.


  • 20 Watts
  • 10″ Speaker
  • 3-Band EQ with Mid-Shift
  • 2 Channel Lead and Rhythm
  • Aux Input and Headphones Output

This amp continues to get five stars for its ease of use and great tone. Many are impressed with its overdrive, exceeding the expectations of many given the amp’s price. Many are also pleased with how the amp does high-gain tones via the Mid-Shift button.

There are a few users who feel that the amp is not as loud as they want it to be, but since it only has a 20W amplifier, it’s more of an actual limitation than an issue.

If you’re looking for a budget-friendly solid state amp, then check out the Acoustic Lead Guitar Series G20 amplifier.
