We continue „effective-ly“ with a third article written by Bernd Meiser, this time looking at the MXR Distortion+ device. I remember well how, when it became available and known here in Germany in the mid-1970’s, it was the go-to distortion device. Personally, I did not like it a lot, preferring the pre-amp overdrive of my, at the time, Fender Twin Reverb in conjunction with a Compact Phasing A that could be abused to get a 20 dB boost. Still, there is no denying the Distortion+ represented a kind of breakthrough – it is a most important stomp box.
