Happy Fuzz Friday, everyone! Hope everyone is having a good end of the year and holiday season.
Here's the Suhr Rufus Fuzz. If you ever wanted a Fuzz Face with an input buffer and big ol' ton stack at the end, this would be right up your alley. Here's the schematic for reference. Should be able to squeeze it into a 1590B.
