We include a standalone HTML file with each of our boards that helps show you what parts go where (find it in the “Build Docs & Extra Info” Tab)- just extract the zip file to a folder and open the .html file in your internet browser. You can use the table on the left to tick off the parts as you source them / add them to the board – we found its a very handy and a big shout out to Interactive HTML BOM Plugin which is a free plugin on GitHub used to generate these.

Vesuvius Fuzz - really loud fuzz. This board is a modded version of the EQD Erupter, using some easier to find transistors and extra trim pots for ease.

The main dial set at 12 o’clock gives you a slight volume boost and days of sustain. Turning it left and you get a more gated, lower output - turn it to the right and you get a louder, more refined.  Our board has an additional trim pot for output volume which can also be wired to a pot to give you additional control over the output. We've also added a trim pot to make it easier to adjust the feedback resistor - easier than swapping/changing resistors around aint it!
