So, exactly what is an OD-308? It is an Overdrive/Distortion that possesses all the qualities I've always wanted in an Overdrive/Distortion. It's based on a RAT2 circuit but with lots of changes. I've taken all the great qualities of the RAT (smooth FAT Cutting Gain with Rich Harmonics) and enhanced them. And I removed all the things I didn't like (fuzziness, mushy and bassy gain when distortion knob is maxxed, unfocused gain structure).
The OD-308 is really three pedals in one. The 3-way toggle switch gives you 3 very different options. FAT Mode — triggers an LED for a FAT, Smooth, Harmonically Rich Gain. FINE Mode — triggers 2 1N4002 Diodes for a Super Rich, FAT and Smooth Gain that is unbelievable for Pinched Harmonics. BOOST Mode — the middle position of the toggle switch, is perfect for creating a Silky Smooth Clean Boost. BOOST Mode is also great for crunch and that Famous “Marshall Brown Sound”.
But I didn't stop there; I recently created a Mod for the OD-308. The standard OD-308 has a pronounced mid boost to help you stand out in a mix. My recently created “OD-308 Vintage Mod” (Instructions for this Mod are available for free to all OD-308 users). This Mod gets the OD-308 closer to the Famous Vintage RAT2 vibe. It flattens the EQ and replaces the 1N4002 diodes in the clipping circuit with 1N914 diodes that were used in the original Vintage RAT.
This is, by far, the best OD/Distortion pedal I have ever played. It is “The Sound” I've always heard in my head but was unable to achieve until now! If you're unhappy with your tone or maybe you are happy and just want another great OD Pedal to add to your arsenal, the OD-308 is definitely for You!
