Hej guys,

Because I was tired of opening up my ESP with active pickups, to check if the 9V battery voltage still was OK, I developed a small pcb which is easily mounted inside my guitar.

It will make a LED blink when the battery voltage drops below 7.7V, works like a charm...

I made a couple of them and have put them for sale on ebay.
Should you be interested, more info and demo stuff can be found here:
