Re: Been a while since we had a HARMONIC PERCOLATOR thread,
I just recorded a demo yesterday of a build on my latest PCB. Looks incredible and sounds so big and doomy. Voltage starve is super useful to tame it down a notch but overall, wow. Really picks up anything this is going on with the guitar, if you tap it you can hear it through the pickups. Also picks up subtle picking technique even at full bore.
This is just riding the volume knob up so you can get an idea of clean up.

I'll get some photos up in a few minutes.

If anyone wants one before I start getting enclosures with labels printed let me know. I would love to hook up a ILF'er. I plan to retail these at $229 for those who are curious. I have one ready to ship now and will have a couple more come next week.

It looks really great D. I hope you sell them all quickly. I'm sure you will. What Ge's did you use there?

Re: Been a while since we had a HARMONIC PERCOLATOR thread,
Here are a couple recycled parts Perc cicrcuits. The first substitutes an NPN Germanium transistor for the NPN silicon,
so it is an all Germanium circuit and a little lower gain than usual. The second is a Perc circuit with the addition of a special fun knob.[youtube]http://www.youtube.com/watch?v=9OhlLmuCY2A[/youtube][youtube]http://www.youtube.com/watch?v=tWAXxTGx8V8[/youtube]

I think this may've been the first SoaringTortoise video I watched:

Re: Been a while since we had a HARMONIC PERCOLATOR thread,
Thanks!! I used the russian military equivalent of a 2n404. It's a MP16B. You can find silver cans pretty cheap but I prefer the look and sound of the black military spec. In reality each transistor sounds a little different so I test every one on the breadboard at different voltages before soldering them to the PCB.BetterOffShred wrote:It looks really great D.

Nice man, I got some 16's, but yeah I agree even 2 from the same lot with similar gains sound different. I have used 42's in my last 2 percs. Thanks for sharing.

Borrowin' lordgalvar's and runnin' it into The Accountant.
Hopin' to convince skully to build me a purple one.

Gonna need clips of that.
Why Accountant after it?

Re: Been a while since we had a HARMONIC PERCOLATOR thread,
I need to get a new SD card for my camera.
Using The Accountant as a limiter of sorts. Also, adds some nice squash.
I usually run the Fredric Utility Perk cranked into The Accountant. Way too loud otherwise. Full up the Fredric has more gain than the Dirge. I like the Even Anguish better for lower gain sounds though. Has a nice ring to it. Doesn't really need to be limited at lower gain, but The Accountant makes it better for that chicken pickin'.
