VU meters for pedals?

[angrykoko]

ValveWizards GlassBlower "GTI" has a LM3916 based led VU meter that you might try.

The VU meter is done in the usual way by sending the audio to a peak level detector and then to an LM3916 audio-taper LED driver. Although this chip is designed to drive 10 LEDs, it is not easy to get the full scale out of it with only 9V available, so I used six LEDs.

It's the last one in his build pdf and the full schematic is there toohttp://www.valvewizard.co.uk/glassblower.pdf

That guy always has amazing stuff.  As soon as I have time I'm building an engineers thumb.

I'm also very interested in this curious how you'd hook something like this up to a pedal, to show output

(I'm not even remotely interested in it being properly calibrated, I just want to see the meter move when I play. )

Hell yeah! Guitar players are the coolest. My guitar player took his tuner off his board so he could have room for another dirt pedal!

Not that the tuner is important, it isn't.  But if your guitar player still doesn't have enough room, he can always Velcro new dirt pedals on top of existing dirt pedals.

right he just tunes to me after I tune, I suggested a bigger pedal board.

If you get enough dirt pedals turned on nobody will know you're out of tune anyway.

I was thinking a full on spectrum analyzer.  Like this:

That would be so cool on a amp build
