Original Prototype 432k
Original 432k Distortion Box prototype
Sorry, this item has sold.
Price: $389 (with b-stock meter)
Sn# 417 Up for grabs. The original proof of concept build of the 432k distortion box. To make it official I recently etched a top panel and gave it a b-stock meter. The box finish is a little rough around the edges. The internal board was built for testing before the first commercial version was sent out. Figured it would be best to send this out into the world instead of sitting on a shelf in the shop.
I’ve also etched “432k Original Prototype” across the bottom so there is no mistake that it is the first one.
The 432k Distortion box is all about signal routing. One distortion circuit with an active hybrid diode/transistor ladder filter (with resonant feedback) for tone control. Another with a clean pass signal. Both signals are merged together and “glued” through a transistor drive and op amp style fuzz. A feedback noise circuit is added in for fun. Also equipped with CV in for filter control. ***Use CV to control the filter.
This model has an additional mod that switches the distortion fuzz from a sharp more mid range silicon fuzz to a softer germanium fuzz.
Things I enjoy about this pedal:
- Hyper Fuzz tone
- Hybrid Diode/Transistor ladder filter.
- Enhanced resonant feedback for more expressive tones
- Clean pass lets you bring a quality signal back into the compressed distortion
- Op Amp style fuzz at end of signal chain. Dial in harsh tones and smooth them out.
- Great for guitars and keyboards
- CV filter control. Use CV in to control filter with modular gear, synth or CV pedal.
- Low cut toggle for guitar use.
- True Bypass
• Knob controls:
Distortion: Volume of Distortion
Filter: Filter Frequency
Resonance: Active resonant feedback
Clean: Clean signal
Low Cut: low end roll off
Transistor: Transistor gain/drive
Op Amp: Op Amp Fuzz
Feedback: Noise loop (works best with sequenced sounds)
**Requires a regulate 18volt DC Supply. Standard negative tip with a min of 150ma. (not included) Will run on 12volts for a dirtier sound. Lower voltage will affect the smoothness of the filter.
***All purchases done through Paypal. Units are always shipped ASAP. Please note when purchasing from eBay shipping charges may be vary.
****International shipping can vary. Typically I will credit back any difference when your unit is ready and I am able to verify exact shipping to your specific location.
