Harmonic Fusion Engine
« on: November 27, 2012, 04:48:37 AM »
Thought I'd give it a thread here too..

Here's something I threw together. It's called the Harmonic Fusion Engine and it's a marriage between two great effects with Harmonic in their name.. The Systech Harmonic Energizer and the Harmonic Jerkulator (By out pal Tim Escobedo). It also incorporates Jack Ormans SWTC. What I did was removing the gain stage from the energizer and use the free opamp as an input buffer. Also I Fixed the bandwith pot at max. Finally I blended in some of the clean signal into the jerkulator to keep some bottom end when the frequency is set high.  I used 2N209 and 2N3404's for the jerkulator. The schematic misses two 220pF caps from B-to-C on both transistors for noise reduction. They are on the vero.

Schematic:  https://dl.dropbox.com/u/1849818/hfe-fixed.png (ignore the comment on the range pot.. it's fine)
Vero:          https://dl.dropbox.com/u/1849818/hfe-verified.png VERFIED  ;D

Tight fit:


If you lower the footswitch you can even squeeze in a battery.

BUILD IT!

Just wanted to say thanks for designing and sharing this one. I got it together today and absolutely love it!! Some really great fuzz wah type sounds in there. I used 2n5089 for the NPN, 1n270 diodes and removed the 22k to the volume (in the hope of giving it a bit more volume). Cheers!

Remove the diodes for volume.. Watch out though it's LOUD

Cool, I hope you like it. You can always tweak the jerkulator side to taste.
