Sea Bed Delay Dirt Mod?

[EisengesisFX]

One of the first things I built in this DIY pedal journey was the Fuzz Dog Deep Blue Delay/equivalent of the PPCB Sea Bed Delay, the Echo Blue Delay.


I'm now building a Sea Bed for a friend but it's ultimately gonna be one-knob feedback machine more than any sort of traditional delay whatsoever. So I'm looking to add the dirt mod that Lee of Fuzzdog includes as an option in his layout:



Since the optional pot and cap in his layout have solder points, I just want to make sure this correctly to allow the Dirt Mod to be easily incorporated. As best I can tell, C23 Fuzzdog = C10 PPCB:



So where do I go from there to replicate the mod on the Sea Bed? This will definitely be a lesson in schematic comprehension to me, but am I correct in thinking that
1) I connect one leg of the 100n cap to the middle leg of the Dirt pot, then
2) Connect the right leg of the Dirt pot to PT2399 legs 11, 12 and 13?
3) Also, Where do I connect the first leg of the Dirt pot to?

Thanks to all in advance
