Overview
The 2020 version of the RabbitHole is the exact same circuit as the previous version. The PCB has
been re-designed to conform to the more recent style of 1590A layouts on mbp.
I’ve adopted the Ram’s Head as the “default” BOM for this version, as it is very popular and a good
representative of what the BM sounds like. However, there are many varieties you can build. In the
zip file for this project I have included the old spreadsheet that has different BOMs for a few versions.
Also, I highly suggest you check out the Kitrae Big Muff pages: not only for a complete history of the
effect, but for additional possible BOMS.

Technical assistance
