[sdiy] Leaving off a pot?

[Sam Ecoff]

Hi,

My first ever DIY project is nearing completion and I have a  
question. I'm building Ray Wilson's envelope generator (figured it  
was a pretty safe first project and I'm desperately short on ADSR  
generators in my rig).

I'm a firm believer that pots go on inputs but not outputs on  
modules, so I've decided I want to leave off the output pot of his  
design. So, my question is, is it just a simple matter of leaving it  
out and keeping the 1k resistor between the pcb and the output jack,  
or is there something more involved?

I'd also like to add an LED to indicate the EGs status. I know that  
an LED needs a resistor, but that's the extent of my knowledge. Would  
I just wire the LED in series with the 1k resistor that's already  
there? If so, would the resistor go before or after the LED? What  
(besides physical size) should I look for when sourcing an LED? I'd  
prefer not to go with the hot-melt mounting technique, so I'm hoping  
to find either a panel-mount LED or one that can sit in an enclosure.

Thanks as always for the help to the newbie.

Sam E.
