Massive thanks to @phi1 for his original schematic (https://forum.pedalpcb.com/threads/arachnid-dual-eeprom.1818/) and to @Moltenmetalburn for designing the PCB from this thread.
This was probably my hardest build to date. The off board wiring was the trickiest bit with the mods that I wanted. It was a PITA to wire and took ages to get all the built parts into the enclosure. Then it didn't work first time due to a short from one of the LEDs so had to remove it and used insulation tape to get it sorted.
I had the FV-1 pre-soldered. I added a switch to keep the dry signal in all of the time and the wet signal to be added on top which is the little switch that I superglued to the side of the OUT jack.
I wanted to access the internal patches from the FV-1 which I actually really like on the toggle switch near the foot switches.
At the moment, the left foot switch alternates the EEPROM which is signalled by a bicolour red/blue LED. I am using the Octagon and Module8 EEPROMs at the moment but I might do a custom EEPROM. Also MAS Effects sell a customisable EEPROM for FV-1 builds which I might try out as well at some point. The faceplate looks great but I made a few errors with number placement and font size but its not big deal. If it bothers me in a while I could order an updated version.
There are some great sounds available in this pedal. It would be cool to have even more EEPROMs accessible. It would be great to have 4(+) EEPROM accessible from this mod - I would love an EEPROM each dedicated to reverb/delay/modulation/weird stuff (ring mod etc.).
