Title: Frank Clarke's Hot Harmonics
Post by: Aharon on September 09, 2007, 12:07:46 AM
Does anybody have a link that works to frank's schems?..........if not maybe somebody can PM me the schem?
Thanks

there's a version and a link to the source on gaussmarkov.net:  hot harmonics (http://gaussmarkov.net/wordpress/circuits/hot-harmonics/)

all the best, gm  :icon_biggrin:

Title: Re: Frank Clarke's Hot Harmonics -- here's a vero layout
Post by: twangquack on September 10, 2007, 03:42:57 AM
Here's a vero layout for anyone interested in building a vero-based "Hot Harmonics."

http://www.geocities.com/twangquack/Hot_Harmonics.html

Bear in mind this is obviously not verified and I'm only about half-way through my build ... but I triple-checked against two schematics of the same circuit so I think this should be OK. I'll let everyone know once I have it up and cranking.

I still have to sand, prime, paint, and overcoat the enclosure, though. And this is also a "2-fer" project where it will share space in a plenty big box (total of 6 knobs, 2 footswitches and one or two toggles) -- I'll be running it in series (true bypass footswitching for both circuits) with a TS-808 clone that'll have many of the usual deluxe mods so I can be completely insane ... or perhaps only partially insane. I love multiple gain stages where no one stage or pedal is maxed out. After hitting my Red Llama clone in the butt with the recent AMZ Mosfet Boost build, I'm really liking the fun of this type of pedal usage. And after taking my Keeley-modded Sparkle Drive and changing out the clipping diodes for various combos of Mosfet, JFET, red LED and SI stuff, I have a pretty good idea of what I want to do with the TS-808 part of the pedal.

I think much of the toggle-switchdom will involve selection of clipping diodes (you know it had to rear it's ugly head: more diode clipper discussion!); I happen to have grown quite fond of using the softer-kneed stuff. I have some various MOSFETs, some LEDs (I tend to like red, though some like yellow), and I also have some 1N34A's to try in series to boost the clipping threshold as opposed to using one on a side against, say, a red LED. But I also have some old standbys (4148's and 4001's) so I'll try all sorts of symmetry and asymmetry and decide what I like best. But all in all, the TS-808 is certainly not the most adventurous part of this project.

I'm excited to see how the Hot Harmonics half of this shenanigan sounds ... I know I LOVE the Red Llama clone, so the CD4049UBE is plenty dandy in my book! Sounds so great played loud I'm not even worried how much the neighbors hate me.

This is a link to Frank Clark's site as of Feb 06th 2002:

If you go to the Hot Harmonics page fortunately you can still find three versions of the circuit:

Only slightly OT:

The hunt for Frank Clarke is a recurring theme, and so is what I am trying to find: a schematic that Frank once posted for wiring a split coil humbucker is a strange and wonderful way, that I can neither remember nor find. Anybody got a clue?

Thanks,
Ben

What way are we talking about? I know a decent amount about pickup wiring to have a go at anything you can throw at me  :P

Best I can recall, it was something like using one coil as an inducter, but I really son't remember more, except that I wanted to try it.

That's very interesting... I'll have a bit of a think/look around and see what I can come up with. Do you mean using the coil as part of a tone circuit?

Anybody still have the "Clean Face" schem around?

Um... I think so? :/

i just build a hot harmonics, but the octave control acts as another gain control, i hear no octave effect going on...

is the way it it or am i wrong??

please help
