Hi all,
Just received a 1.5v DC meter to put in my amp project just to look cool. Opened the box and DC leapt out at me - of course my guitar puts out AC!
Not to be outdone by my own self I found this thread about converting ammeters from DC to AC.

Can I construct a wheatstone bridge (my first ever - whoah!) to change this to measure AC guitar output as a signal strength meter?
Are 1N4148 diodes sufficient or is the Forward voltage at 1v too little?
I have other diodes like 1N4001 at my disposal.
Its just a bit of fun so accuracy is less important than 'look'.
Thanks
