Moderator: modified the link to go directly to the Bajaman's schematic and added the schematic to this post. Make sure you check the article, though, it's a treasure trove of information regarding both Bajaman's schematic and active pickups.

This diode does nothing to the signal, it is only reverse power flow protection so you can use anyone.

Ex. 1N4148 ? Thanks

Yes, it'll work perfectly!

An option something better is to use an schottky diode, anyone. There is a little voltage drop (aprox. 0,6v) when 1N4148 is used in this way, it does not affect your tone when the battery is fully charged.

Another good Idea is to use it in parallel as it is used in pedals.

I found mmbd diode footprint and add it bit I cant understand one thing 4205 pin 4 ground and pin 7 to 9v+ is it ? Or something else ?
