A couple of questions for the sake of good will!
1) Mikko, or anyone at all, does anyone out there know where to put the pots
on the AS-1 project?? And what values??
2) The same for the ARP-filter (the patent) what resistor-values, or where
could I find them??
3) Also, I've worked out a distortion stomp box. Just schematics, nothing
fancy yet and I need a couple of things. First of all could someone check
it. I currently have two versions. The first one is a very simple one. It
looks a bit like this: ASCIIIIIIIIIiiiiiihhhhhh

The same thing here only with negative voltage applied.
The working is ridiculous actually: it just shift the signal up when voltage
is positive and down when it's negative.
That's just fine. But even noise could get pretty messed up. So there has
got to be some voltage control. I thought something like an envelope
follower feeding a NPN-transistor between R3 and R2 (not exactly but you
know what I mean!)
Any help????
Thanks!
Erik
PS: The last one is the second one
