I've got a great sounding harmonic percolator... but...

[goldenmonkeycolor]

I built a harmonic percolator based on the vero layout at tagboard fx.  Used smallbear 2n404 and have tested a number of 2n3565's, nos 1n695 diodes... got the tantalum 47uf and silver mica 100pf and the whole nine yards.(the tantalum vs aluminum electrolytic is a noticeable difference in this circuit too!)

I have the clipping diode switch and I'm gonna put a switch in there to switch between two different 2n3565's- one reversed and the other normal (whatever way is normal i guess is up for debate right?)

my problem is... when i sustain a note I can hear this heavily fuzzed sound underneath my signal (way more heavily fuzzed- like big muff style sustain) when my note has decayed for a good few seconds.  I believe the circuit sounds as it should, but this noise is strange... I'm wondering if that level of fuzz is actually what i should be getting.  it sounds kinda like i'm getting bleed through from clipping diodes versus no clipping diodes... but i dont believe that is actually the case- just an example of the sound.  because i do get a pretty big difference switching in and out my clipping diodes.  and i get this underlying fuzz noise on both settings of the switch.

Is this just part of the circuit's noise?  its not incredibly noticeable, but its annoying me because the circuit sounds so good. Maybe boxing it will prevent it?  anyone experience this with a percolator clone? 

Thanks!

Not sure, but perhaps its low frequencys that are getting more easily distorted?

well i went and messed with the value of the 100pf cap just to see how it affected the tone through my rig and now I cant get it to work at all... wondering if i burned out my germ transistor...

sucks.

it actually seems like high frequencies that are giving the sustaining fuzz undertones

You didn't socket it? 

[goldenmonkeycolor]

i always originally socket transistors.  but the sockets i have dont hold stuff without thick leads very well.  i would not want to rely on transistor sockets.  I got mine from tayda, maybe those ones are just crap?  I've bought the expensive circular transistor sockets that take up a lot of space, but i didnt like those either

maybe i could get better inline sockets (they come in rows of like 40 and you break them off into whatever you need) would buying from a different source get me better quality that holds stuff better?

I got it working again... and ive made a sound demo of what i'm talking about.  ive been flipping around the 2n3565 because it sounds cool and unique going either way... i believe there is some argument over which way is correct isnt there?

so where i get the most of this fizz is the higher gain positioning of the 2n3565 with the diodes in the circuit (i have a diode lift) the soundcloud link explains the order, but the first setting showcases most of the fizz that i am talking about

any help would be greatly appreciated!
