The Guitologist | 2 years ago

In this video, we'll look at a 1971 Hiwatt Custom 50 in need of some service attention. We'll also set the bias and talk about the pros and cons of setting the bias according to onset of crossover distortion on the oscilloscope vs the 70% plate dissipation rule. In the end, we'll demonstrate the tone in a band setting, complete with bass and drums!
