The WA 300 Bass Head is a workhorse that includes a 10 band graphic equalizer, bass and treble controls, adjustable compressors and passive and active inputs for all your tonal needs. This amplifier provides a classic sound with modern performance. Manufacturing techniques and component quality has improved drastically over the last couple of decades, so noise and hum are no longer an unavoidable issue that comes with high volume! The WA 300 Bass Head features low noise Class A gain stages throughout the amp which provide us with a very warm sound with natural, unrestrained response. Unlike Class A/B and Class B amplifiers, with a Class A designs, crossover distortion is not an issue, in fact - there is none! A really cool feature of this amp is the dynamic distortion limiting circuitry, which automatically kicks in when the amp is pushed to its limits. This kind of technology dynamically removes unwanted distortion in the power amp, keeping the THD level of the amp always under 0.3%. That means, when we say 300W, you really get 300W of natural, clean, undistorted power.
