The 2020 version of the RabbitHole is an updated version of the previous circuit. The default BOM for this version is the Ram’s Head, which is a popular choice and represents the sound of the BM. However, there are other varieties that can be built using different BOMs provided in the zip file. It is recommended to check out the Kitrae Big Muff pages for more information and additional BOM options.

1. VOL – This control adjusts the total output volume of the effect.

2. SUS – This control adjusts the total amount of distortion produced by the effect.

3. TONE – This control has a wide range of options. When turned counterclockwise, it acts as a high-pass filter. When turned clockwise, it acts as a low-pass filter. There are many options in between these extremes.
