Harmonic Percolator

[Stomptown]

Here is my finished harmonic percolator. I really like the germanium diode clipping in this one. Definitely a unique fuzz. I was going to etch the faceplate but I like the way it looks as is with the toner transferred from PnP blue. It seems pretty durable too! If anyone is interested in one of the pcb's let me know!

Please tell me that paint job came from a rattle can, I want it!

Ia m not a fan of those knobs but with that face plate it looks perfect. Great job.

Unfortunately, it's not out of a rattle can! It's a gloss black/cherry topcoat enclosure from Pedal Parts Plus. It looks nothing like the picture on the website but that's a good thing; it looks better. 

Thanks for the kink words as well! Those are some of my favorite knobs for some reason (other than the fancy/expensive aluminum ones).

Very nicely executed sir! I am a fan of your work.

I will definitely check em out. Thanks

Your builds just keep getting better...looks great.

I definitely like that color better on your build than on their site! Almost thought it was purple starlight.

Let me vouch for these boards--I did the "stock" specs on one of them and it sounds great. This build here looks to be an Albini version judging by the resistor values. Comparing Albini to stock is quite interesting by the way. Both sound awesome but they're pretty different.

Can you describe tge differences? I'm interested in building a stock  version and would love to hear more...

[Bret608]

No problem!

I think the stock specs are a bit brighter tone-wise and offer more gain than the Albini. To me, it's more a full-on fuzz whereas the Albini is this off-kilter fuzzy overdrive/distortion sound. With the stock I can get smooth, MkII-like sustain on single notes and the volume knob cleanup is excellent. The subtle octave stuff going on as you play up the neck is very tasteful. The "diodes off" setting makes more sense with these specs, but I can't hear the differences between germanium and silicon diodes as clearly as I can with the Albini.

So it's definitely worth a build. Full disclosure--I used tantalums for the 47uf and 1uf caps, and this may make a difference in the results. I guess the Albini still has the edge for me, but this version is on my must-box list for the new year. You could have both on your board and not have them doing double-duty due to the different sounds you can get.

Sorry for bringing up an old topic but I'm looking for some shared experience.  I built the percolator from a layout at tagboard effects and I'm getting some weird results.  First i can tell a huge difference between diodes in and out (not the problem, just something i saw above someone said they couldnt tell a big difference)  anyways, the pedal sounds killer.  but with the diodes switched in the circuit i'm getting this weird static'y noise that only occurs between noon and like 3 o clock on my "harmonics" pot.  with the dioes out i dont get this static'y stuff.  I"ve quadruple checked everything, changed out diodes, etc etc.  But I cant figure it out.  My first thought would be the transistor, but since it sounds fine with the diodes out of teh circuit I dont think it is the transistor. 

anyone else notice this noise?  Its not standard "oh its a fuzz" noise.  if not, could the transistor be the culprit when its just a problem with diodes in the circuit?

Thanks a bunch!

here's the layout

You will get more traction if you start a separate topic in the tech help section.

PCB ??
hello, do tell.

[Stomptown]

They are currently out of stock but I will be reordering very soon.  I will hit you up when they come in.

Dumb question - on the 3pdt board, how come both sets of power holes are used? 

I just got my first package of stomptown 3pdt boards last week - they're great, and pretty small too

If I remember correctly, I accidentally got solder on the extra power pad so I just added solder to the gnd as well so it looked better.
