Was thinking it would be cool to incorporate a VU meter in a future build. I guess my questions are:
1) Could it even work? maybe as a LFO sort of visual feedback, clipping indicator, or a signal level meter.
2) Are there any small enough to fit on a 1590BB at least?
The Beavis Fuzz Lab has them (http://beavisaudio.com/projects/FuzzLab/), but I'm not sure what they're "measuring."
This one does too:

I have seen a fuzz face that had the voltage for the transistors somewhere.. Might have been here or FSB forum. Was pretty cool.
I saw one on diysb where someone bought a cheap meter with the vu on it and hooked it up to the dc jack

^^^I especially like this implementation.
Glad to know some people have done this. Guess I'm going to have to buy some and monkey around.
Can't wait to see how it turns out (and then try it).
Yeah, in my experience people mostly use them to measure voltage, when connecting a "Sag" or "Starve" pot to the DC Jack.
I was thinking a full on spectrum analyzer. Like this:

I just like lots of lights and switches. I may have been a trout in a previous life...

That would be awesome! Spendy though.
Cortex has a digital vu that shows bias voltage on one of his fuzz creations....pretty cool.

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

What do you hook up where, and do you need a resistor, etc? I don't know if it is possible to do what I want in a simple way...
(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!

ValveWizards GlassBlower "GTI" has a LM3916 based led VU meter that you might try.
http://www.valvewizard.co.uk/glassblower.html (http://www.valvewizard.co.uk/glassblower.html) (Bottom of page)
QuoteThe 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 (http://www.valvewizard.co.uk/glassblower.pdf)

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

Not that the tuner is important, it isn't. ;D But if your guitar player still doesn't have enough room, he can always Velcro new dirt pedals on top of existing dirt pedals. 8)

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

You could make hime get one of these,

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

That would be so cool on a amp build :o
