The original Crunch Box was a modified (and updated) version of the old Marshall The Gov’nor , which was meant as an amp-in-a-box simulator of the Marshall JCM800 stack. There are very many pedals out there attempting to sound like one vintage Marshall or another, but the Crunch Box is considered extremely well done even among a crowded field, with the Super version expanding to encapsulate virtually all Marshall tones to the extent it’s possible. It’s so good, in fact, that the higher-profile JHS Angry Charlie is reportedly a part-for-part ripoff with no modification made to MI’s circuit whatsoever. Oh, and it’s more expensive. Naturally, this is contested, but that’s the story around the internet water cooler. It shouldn’t dissuade you if you prefer the JHS, but it won’t have been the first time they’ve been accused of such a thing. Anyway, back to the pedal at hand.
The upper gallery shows a movie of the combined BPs from all networks with sufficient data. The array response function is also shown which is generated using the same processing techniques and stations, except the raw data are replaced with synthetic seismograms with 5 s wide point-source triangle functions. The first and last frames show cumulative time integrated results. Results are affected by radiation pattern, Greens functions variations and array geometry. Warmer colors indicate greater beam power. A small cross shows the location of the peak beam power when absolute beam powers are low.
