I love the blooming harmonics of the Super-Fuzz circuit, yet a lot of those originals are a little underpowered on the output. I prefer vintage-inspired but slightly modernised circuits which have a significantly improved output profile.
This will be my own 25th Super-Fuzz - that’s how much I like the format. And Vitalii has really pulled out all the stops for his version. The original 1968 Super-Fuzz essentially had 3 controls :
Balance (Volume), Expander (Fuzz Amount), Tone Switch : Flat / Scooped.
Vitalii then makes the Tone options fully granular - so you have an additional independent Mids Scoop control, as well as classic Tone control to more finely shape the output.
Controls - Balance, Tone, Scoop, Expander.
The circuit is very much a Univox Super Fuzz at its core. The transistor gain stage is OpAmp-based instead of using typical transistors for that circuit - kind of a mix of Rat & FZ-2. The Tone control blends filtered/unfiltered modes that are represented as a switch on the original Super-Fuzz.
SCOOP controls how deep a Mids Cut is applied on the filtered path. The output stage has increased impedance and 2x more recovery voltage gain.
Volnovakha’s Transistors are : 2SC1815 in splitter/gain recovery, and 2SC2458. Then there are Ge AAP-153 Diodes and the OpAamp selected is the UD1408.
The Volnovakha Super Fuzz is available right now on the Drunk Beaver Rocks Webstore, where 30 units will be available @ $150. I’m really looking forward to this one!
As a rapid prototyping project - there is no time to do a demo - so I will select an appropriate adjacent sound sample - as below!
