Yamaha G100 1970’s - Black half stack

These solid-state amps were Yamaha’s take on Fender’s Twin Reverb, the reigning heavy-weight combo king of the late 1970’s. Their 50 and 100 watt versions are as loud as comparable 50 and 100 watt tube amps; this was far before the days of inflated solid-state output ratings. Yamaha was, and is, a great Japanese company that takes quality seriously. Designed with help from Paul Rivera, they are built well and can fill a big stage.

The Yamaha G100 series amps are built like tanks, and last even longer. 100 watts, solid state. The clean sound is unbeatable IMO for jazz styles. If you open it up you'll see the board is full of JRC4558 op amps, which is why the thing sounds so warm.
