From the post

This appears to be Rockett's take on the Marshall Guv'nor, but with a few modifications. The tone control of the Guv'nor has been replaced with a Baxandall EQ tone stack and the output is boosted with a JFET gain stage (much like Rockett Flex Drive). Should fit nicely in a 1590B with board mounted pots.
