Hey guys,
Just finished my first original pedal.
I'll post a demo video later to but in short, here's what the pedal does:
Delay:
At the heart of the "Icky Thump" is a PT2399 driven delay, with about 800ms max time.
Fuzz:
An LM386-based Fuzz provides some non-traditional Fuzz Face/Factory tones.
A "glitch" control reduces the voltage to get some icky gated sounds.
The fuzz is activated with the bottom-left toggle switch.
Modulation: here's where things get interesting... ?
The center toggle selects either Envelope or LFO driven modulation or none at all.
"Modulation" wiggles the pitch producing the chorus/vibrato sound.
Envelope modulation is controlled by the "sensitivity" knob and is driven by harsh/softness of your picking.
LFO modulation is controlled by "depth" and "speed".
Setting the delay to min, you get a lush chorus sound.
It's still the prototype and needs some tweaking but I'm quite happy with how it turned out.
I certainly didn't reinvent the wheel, and to give credit where credit is due:
The Delay filtering values used are the same as in the Mad Professor Deep Blue Delay.
The Fuzz/Envelope circuit is based on from the Mid Fi Clari(not).
The LFO is a tweaked version of the Tremulus Lune tremolo.
Regards,
Matt.
