[sdiy] very newbish attenuation question . . .

[Terrence McWee]

Hey Kids,

Thanks much for your patience with a question that is very, very basic.

I built a PAiA Hot Springs Reverb (which I love!  gives everything a 
"sealed in a dead sub at the bottom of the Bering Sea" sort of sound.)  
The HSR is pretty simple, interface wise:  you have a 1/4 inch for 
sending the signal in, and a 1/4 for it to come out, with no dry signal 
mixed in, just all wet.  Now, based on my decidedly simplistic 
understanding of electronics, it seems to me that if I ran a wire 
directly between the tip of the IN jack and the tip of the OUT, I'd end 
up with the full strength effect mixed with a full strength straight 
signal-- which, really, isn't much better than just having the effect 
full strength, with no dry.  So, I'd want to add a pot (at least, 
that's what my electronics spidey-sense tells me), with one leg 
attached to a lead going to the IN's tip, and the middle leg going to 
the OUT's tip.

Questions:

1) is my understanding (about the results of simply connecting the 
tips, and then adding a pot between them) correct?
2) would I need any other parts for this (a little non-variable 
resister to buffer the output, maybe?) or is this really just a "two 
scraps of wire and a pot" job?
3) what value pot is preferable?

Lastly, if I wanted to be able to control the mix of the wet signal, as 
well as the dry, would I simply add a pot between the effect circuit 
and the tip of OUT?  Would this pot have the same value as the other 
(as per question #3)?

Again, thanks much for your help; much of electronics is still a divine 
mystery to me, and I need every little info-scrap I can get.

P.S.  Thanks for keeping this list up and running-- I've learned a 
helluva lot just by lurking.
