Vesta Fire / Reagun / Nadine's Overdrive

Second post for today is the Overdrive from Manfred's trace (at FSB). This comes from the same series as it's distortion brother (see the earlier Vesta Fire Distortion post), but the design is slightly more obscure. Still, the inverting input filter path to ground gain pot method on a non-inverting gain stage is used. However, the clipping isn't your bog standard feedback loop diodes. The original diodes in series with 10K resistor are something that hasn't been identified (at least not yet), so i figured this would be a nice board to try on your stash of non-conventional diodes. Maybe some zeners? I'm fairly certain this circuit won't sound bad, no matter what diodes you put in there...

Vesta Fire / Reagun / Nadine's Distortion

Not that long ago, Manfred traced his Reagun Distortion unit and posted the results on FSB. These pedals were sold as Vesta Fire, Nadine's and Reagun brands around early to mid-eighties. All these were made by Shiino Vesta Fire Corporation (SVFC), which became Vestax back in 1987.

Designwise these are not bad at all. This one reminds me of OD250 with BMP style tone stack and a decent inverting amplifier as a recovery stage. Might be worth to try out. Sadly, i couldn't find any demos...
