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…
