Millenium bypass with low-battery indicator - working!

[idlefaction]

Hey all.  Here is a great circuit I just finished cooking up, it solves one of the most annoying things about commercial pedals.  did you ever read a Boss manual where it says that you can tell your battery needs replacing if your pedal won't switch reliably, or the sound quality may diminish?!!

if anyone figures out how to do this with less parts or lower current, please post!



the top bit is a combination reverse-polarity protector from RG's site, and an overvoltage cutout circuit that disconnects the power supply if more than 11V is hooked up (say someone hooks up a 12V wall adapter or something and fries your circuit) - i dunno if it works yet, waiting for some parts to test it out.

the bottom bit is damn cool, and works great.  if the battery voltage is above 7.2V, it works like a millenium 2 bypass.  if the battery is below 7.2V, it works like a millenium but instead of the LED turning on, the LED pulses.  

anyone feel free to redraw this and put it on your site, give me a credit somewhere.  :-)
