[sdiy] spring reverb.......

[Terrence McWee]

The PAiA Hot Springs sounds terrific-- provided you're looking for the 
"I'm sealed in a dumpster at the bottom of the sea" effect (which, 
incidentally, I am.)  Unfortunately (or, from a 
creative-experimental-soldering-iron-in-hand perspective, perhaps 
fortunately) it's a very barebones affair-- *NO* controls to speak of, 
save the internal "tuning" trimpot.  Basically it's just 
input-->MAGIC-->output.
