The parametric EQ on the Yamaha G100-212ii allows for highly customizable tone shaping, which users find superior to other amps with similar features.

The G100 series amps have a real spring reverb, which is praised for its quality, though the onboard tremolo is noted as excellent, particularly in the G50.

Owners report that the G100-212ii is particularly loud, with the clean channel often being too powerful for in-home use, even at 2-3 on the volume dial.

Despite its weight, the G100 is recommended as a reliable workhorse amp, especially for those seeking a solid clean platform for pedals.

The Yamaha G100-212ii is often compared to the Roland JC-120 for its solid-state clean tones, but with a more versatile EQ and reverb.

The first-gen G-series amps lean towards a trebly tone, differing from the more balanced cleans of the Jazz Chorus, and lack the built-in chorus feature.

Some users replace the stock Yamaha drivers with vintage alnico speakers for improved tone, as the original drivers may sound flat to some.

The amp is described as a great "pedal platform," especially when using pedals for metal or thrash, as the onboard overdrive may not suffice on its own.

Some owners mention that the distortion in the G50 amps is more akin to fuzz, especially at high volumes, which may not suit all musical styles.

Any latching 1/4” footswitch can be used for channel switching on the G100-212ii, as it doesn't require the original footswitch.

The parametric EQ's potentiometer is reportedly difficult or impossible to replace if it breaks, posing a potential maintenance challenge.

The G100-212ii is noted for its heavy build, and users recommend adding wheels for easier transport due to its significant weight.

In the U.S., $250-$300 is a reasonable price for the G100-212ii; $350 might be expected due to rarity in regions like the U.K. or Europe.
