Anyone add an LED to their Pic Wah? How did you do it?

With the effect switched on, none of the lugs on the switch show 9v.
Relays are beyond my knowledge.

That switch is unfamiliar to me, but check if there is continuity between the two unused legs (on the upper left in your picture) and so you can use it to switch the LED.

Or has the Teese RMC4 wah never been traced? As far as Google goes (you wanna buy? buy? buy?) there seems nothing to be found!

could be a firefox problem but link doesn't download the schem?

..just a blank page

Sorry. Works here in IE and Firefox. "Save as" doesn't work either?

nope.. but could certainly be the way my firefox is set up.. it just opens a blank page...

can confirm it's sweet as in chrome though

Question, when you write the value 472E or 10E on a resistor is it Ohm?
and when you write 10/25 or 100/25 on caps is it 10/100uF 25V ??
thanks

It is, yes.

And yes, it's capacitance / rating.

Thats 3 digit codes http://www.hobby-hour.com/electronics/3 ... istors.php

Thanks Dirk

When it's stamped on SMD resistors, it's the code indeed. But on the schematic above, 472E definitely means 472 ohms.

You meay see 100R too, R standing for ohms too.

edit : just remember this:

analogguru wrote:"E" is used in german countries to describe "Ohm". It is derived from the german word "Einheiten" which means: units.

"E" is used instead of the Omega-symbol to avoid confusion with 0 - which may occur especially on bad copies... e.g. "390" is this now 39 Ohm or 390 ? 39E instead gives a clear answer....

I never seen 472r value resistors bro. Dirk, clear it up please

sinner · Post by **sinner** » 27 Aug 2014, 16:18

Ok. I just looked on the schematic and it cant be 4k7 on emitter resistor. So I'm wrong

Indeed...

possibly a typo (supposed to be 471? = 470ohms)?

Intripped · Post by **Intripped** » 31 Dec 2014, 17:16

is C25 really supposed to be 47nF?
it's a bright cap on the volume trimmer/pot, isn't it?
i've a 47nF in my wha pedal at the moment and i can't adjust the volume properly
maybe 4,7nF or 470pF would be the correct value?

thanks (and happy new year!

)
