apologies if this reaches you twice, it seems to have been 
swallowed by that big black hole in the center of the net.

That sounds pretty good. The attack sounds a bit muted to me though, is
that deliberate or should it have more bite? 
it could do with a little more bite, yes. it's the neck pickup 
with the tone pot at the guitar closed slightly, that's the way 
i usually play the super 60. this way, it stress-tests our setup's
capability of generating higher-order harmonics during attack.

   Yeah, fix the rectifier. I had a quick look at it and
it looks like I did
something fairly obvious (its basicly a compressor, but with a waveshaper
instead of a linear gain).  
 the shaper code looks familiar. admit i'm hoping for a performance 
 and quality gain. 
Yup, I adapted what I had around ;) I think something symmetric and harder
might be better though, I'l see what I can do. Maybe it should just be a
peak following compressor... my original though was that the power supply
sag would cause a distortion, but maybe it wont. 
whatever it does, it helps. ;) probably because it adds more
distortion in the attack phase. so it may not do exactly what
is intended on the smaller scale, but what is intended to be 
modeled overall.

...
 I think the speed will go up dramatically when its
bolted into one plugin.
I want to get the ordering right first though. OTOH there is still mic
effects to be added in :( 
speaking for my selfish self, i'm just glad i don't have to
care about mic placement at all anymore.

i'll be happy to create more iir 'convolvers' or extend 
'unmatched' for more impulses though, as long as they can be 
made to converge.
